What Is Pneumonia? 

I swear if you guys were around while I was in College, I would've gone on to medical school. You make anatomy so interesting.

Laying in an Australian hospital bed & hooked up to oxygen to treat my pneumonia that I seemingly came down with over night, and your video has provided me with more info on how this has happened than any of the doctors/nurses/medical staff here have managed to explain. Non smoker, I don’t drink, I didn’t have any known infection before the pneumonia. Literally woke up with it and went downhill from there, which then lead to sepsis. No doctor has been able to adequately explain what the hell happened to me - I had to find that info here. Thank you!

6 years ago, i guess on 1st of December i was admitted to hospital for the same disease... When doctor saw my x-ray he said "one week more without treatment and u are dead"... They inserted a tube in my lungs, i saw a green colour liquid coming from it. But as i was too late, they said liquid has hardened so they need to perform surgery instantly. Thankfully I've got time...

It's left because it has 2 lobes. The right has 3. I've never taken an anatomy course in my life.. not even a biology course in high school. I just found your channel a couple days ago and watched 3 of your videos so far. I really enjoy them and I learn so much. Thank you!!

As an OLD Respiratory Therapist (30 plus years 67- 2001) this was a very good explanation .

I am not a student of biology but you described pneumonia in such a way that it is clearly understood to me, great video

You are an amazing lecturer. The wealth of knowledge you have is incredible. Your presentation is smooth and easy to understand. Thank you so much.

I’m 30 yrs old, just got diagnosed with pneumonia after struggling with some other illness, and this is just the video I needed to see. I’m ultimately in good health, I couldn’t wrap my mind around how I came down with this, but you made it make sense. Thanks for being super thorough !

My mom was hospitalized with this for a few weeks and got out almost a month ago, she would’ve died if my dad didn’t take her to the hospital She’s currently recovering now and is doing well :)

I think the Lung Institute's motto is, "When you can't breathe nothing else matters" and OMG that is soooooo true.

This is one of the best sites on RU-vid, where have you been all these yrs. This man does a excellent job explaining everything, the other man too. I just love everything they talk about concerning the Human body. Now, I better understand why a relative died from pneumonia (due to aspiration fr. feeding tube) 8 yrs. ago this video explained it very well. Jonathan, I love the way you explain everything that's a true talent.

I've had pneumonia many times, my health kind of sucks and I always get sick (first year in my life I haven't been sick at all, because of the coronavirus). I never realised how dangerous it might be, because my mother always notices the changes in the sound of my coughs. It's nice to know what is happening in me when I have those. Thanks.

Left side= 2 lobes, right side = 3 lobes , one lobe of the right is missing . Love this channel so much.

Thank you. I've been having serious asthma problems that has hospitalized me twice in the last 1 1/2-2yrs. In Dec 2019 for pneumonia and I thoroughly enjoyed your video. Hopefully when my insurance finally kicks in I can be fully treated for my breathing problems. I liked how you presented and explained your information. Great job. :)

Thank you for posting content about the respiratory system. I'm a Respiratory Therapist, I've been doing this for 10 years, and I still enjoy watching content like this. I would like to see more on the internet, but thank you for taking the time. I appreciate it. Good luck guys!

I’m not a Med student but a massage therapist, I’d definitely like to see sciatica video. Or frozen shoulder, the shoulder girdle is a very interesting area that people hold a lot of tension. But I definitely love the videos!!!

This guy got some Owen Wilson in him.

This is interesting to me bc I had pneumonia as a child and was hospitalized, never really understood what happened to me until now. I kinda see my body as a badass now to have dealt with that when I was so small. Thank you for the video!

Another great video! Your channel is educating more people than the Discovery Channel! ☺️ All information relevant and elegant in the simplicity of how is explained. 👏🏼👏🏼👏🏼

It's a left lung cause it has 2 lobes, not 3. Makes space for the heart.

"We shouldn't be eating 24 hours a day 7 days a week" Stop judging me.

His explanation is amazing. It feels good to know about your body anatomically and even functionally. Keep up the good work.

It's really helpful for me, that the keywords are on screen. I'm not a native speaker and listening to you and see the words written down is a good training :) really great work. Thanks

This guy knows more about anatomy than most MDs I've met. Great video Jonathan!

Exceptional presentation, clear and easy to understand. Thank you for taking the time to make these terrific videos.

Love your channel, I learn so much. Been married to medical doctor for more than 40 years and I finally understand so much from you. Thank you.

Fantastic segment! As a patient with leukemia who just had a bout with pneumonia in the hospital, you enlightened me about my experience! Thank you!

Great explanation - really helps me (nursing student) put all the information together and understand it. Keep the videos coming and thank you!

I really wish i could have you as my teacher in med school... The way you explain is so clear...👏

In school , we are taught all these things but I was never able to imagine these things and how they are but thanks to you now I know what's inside of human body. Thanks 😊

Love everything about this video. With COVID going on this is a very clear and informative video. Thanks for making it.

This is my first video from this channel, but I already love it! The visual aids are great, and the information is well-explained and presented. Thank you for these videos!

Really great explanation! Hope the non medical professionals also enjoy this!

Thanks! Learned a lot. Just recovered from pneumonia and wanted to know the ins and outs of it. Thank you again for your great work. Very informative and yet easy to grasp.

Fantastic teaching. I get pneumonia most of the times and hearing the teaching had made me realise how.

I had pneumonia February of 2019. I was sick for about 2 weeks.. I have never felt so terrible before in my life. I couldn't keep ANYTHING down, so I developed a food phobia for a couple of days after I started feeling better. All I could eat was raspberry sorbet for those couple or few days.

I was trying to pay attention but kept thinking about how close he was putting his hands to his face ... the hands that had just touched cadaver lungs. 😂

I've had double Pneumonia about 3 years ago. I was in the hospital for 9 days. I was in a bad way. Respect to our NHS here in the Northern Ireland. UK. ☘🇬🇧💙😇🙏🏻 they done a great job. 🙏🏻💙

He makes this so understandable! Wish my lecturers were like this

Thank you for being so clear. My husband is at end stage COPD and for the last 2 years has been declining. I have struggled to understand the difference between bronchitis, pneumonia, and "chest infections". I'm off to hunt down your bronchitis video now.

Great video, I had pneumonia in 2018 it’s horrible and I was unresponsive when I got to the hospital. Luckily I had a great doctor and amazing nurses.

You two are just great!!! I practiced massage therapy for 26 years and from the very beginning anatomy and physiology has been my passion! Learning from you two is simple, entertaining, and effective!!! You simply are THE BEST! Thank you with my whole self💫 How about a video about IPF?

These discourses are absolutely wonderful. You make it so easy. Thank you very much, please keep them coming. Kathleen

I've had pneumonia. I would describe it as like trying to breathe though a blocked straw

I love this channel. Always, always informative. Thank you.

Perfect explanation and good for the general public to know given the new confusion trying to stir in news media and social media...AGAIN! Thanks for the video!!

I love watching all your tetorial illistration and I'm a visual learner and yourself by step of explain the functios of the anatomy along with disease that would or could take place, gives me a thoroughly understanding of our bodies function of organs along side of how they correlate with the assistance of our own bodily fluids muscles, tenants and soo much more.this provides me with a point of action of how our body can heal itself with proper care apart from medical interventions and how it works for us to better heal the sick in different many cases. Thank you very much for the thorough explanations that break it down into layman's terms for us. I very much enjoy all your videos, cuz we all know someone or another that deal with disease and illnesses and I have an a better understanding as to why our bodies go array at timesand why it does but know I have an educational knowing of why it takes place and how it develops illnesses and disease. Thank yiu keep bring your videos on. Josie S

I had an opportunity to hold a “plasticized” lung. It was totally fascinating, a true honor and another reason to love my lungs!

This video was educational and interesting all at the same time. Your instructor breaks things down really well to help simple people (myself) understand the anatomy of the human body as it fights viruses, bacteria, and infection. Thank you for creating this content.

Thk you so much for this great video. I'm one of those patients just now recovering from this and your presentation helps me to understand what Pneumonia is and how it affected me

Awesome explanation, i came on to this video with a causal browsing and never expected you will show a real lungs!!! It blowed my mind!. Good job there to the person on the video.

Your videos are absolutely the BEST! Thank you.

This is my 3rd time with pneumonia so interesting to understand my body truly isn’t secreting or creating anything to fight off infections. Nice job body

These videos are fascinating. I’m a homeschooling mom and love these for my kids to watch!! You’re so much more interesting than I am!!😉

Very interesting and informative video presented in a clear manner with cadaver examples.

Since I've been watching you, I'm more aware of my gut and other organs. I'm kinder to them , but breathing deep breaths more often then I did, ( Shallow breathing) .I also visualize the food and liquid's going down to my gut. You both are amazing. Keep on doing what you are doing , we are listening and need this kind of information.. Your both are Blessed... Thanks again. Iv had pneumonia years ago so this yellow green stuff sometimes comes up every now and then I don't know if that's connected I kind of don't think it is.

Thanks for a great explanation of the lungs and pneumonia! I really enjoyed it.

i love these videos, just cam across this channel tonight and i love how its very educational (love it)

You guys have a talent of explaining everything it's very easy to understand ....your gift to the world it teaching...👍

Almost died from pneumonia caused by swine flu yrs back!!! Was a healthy 18 yr old single mother when I got it. Went shopping earlier in the day for an early (19th) bday present with my mother. Came home and took a nap because I was feeling fatigued and woke up not being able to breathe. Was in ICU, out of it, with life support next to my bed for a couple days..... within 12 hrs of taking a nap. No doctor or nurse thought I was going to make it. I still remember the day I came to in ICU and nurses and doctors were RUSHING to my bedside. It took almost a year to figure out what it was because it was such an early case. Happened at the end of 2008 but Swine flu wasnt considered a pandemic until 2009. Stayed in the hospital for a month. As soon as I got out of ICU they put me in the ward with heart patients because the infection had taken such a toll on my heart, i had to wear a heart monitor the rest of my stay. Will never forget getting all those blood thinner shots in my stomach until i had enough strength to start walking again. Viruses SUCK sometimes.

My Grandpa died from acute pneumonia last February so this video had a special touch for me. It's amazing to see what might have been happening with his lungs at that time

Really enjoyed your video. Made it so easy to understand. I have Lupus with lung involvement so I've had my share of pneumonia.Going into my blood stream and very ill. So glad I came across your video. Love it.🤔🤔

Thank you for showing and explaining Human Anatomy so clear for everybody to understand.

Can you show organs with cancer? I think people need to be aware about this illness. Amazing content!

When a bacterium that is part of the normal microbiome of the lung becomes invasive and causes a lung infection, that is called an *opportunistic* infection. The bacteria of the microbiome are normally held in check by the immune system *and* the mechanical barrier formed by the endothelial cells which line the respiratory tract. When an organism of the microbiome exploits a weakness in one of those defense system, it is exploiting an opportunity, hence the name “opportunistic infection.” In addition to bacteria, viruses (e.g. influenza, RSV, SARS-CoV-1, SARS-CoV-2, etc) and fungi (e.g. Coccidiomycosis, Histoplasmosis) can also cause pneumonia. When viruses attack the respiratory tract, they damage the endothelial cells that line the respiratory tract and thereby create an opportunity for other pathogens (bacteria or fungi) to breach the defense and cause a secondary pneumonia. This is another example of an opportunistic infection. Antibiotics are useful drugs to treat *bacterial* infections. Anti-fungal drugs also exist to treat *fungal* infections. But there are (as yet) no drugs that reliably work against respiratory tract viruses. At this time, only a functioning immune system can clear a viral respiratory tract infection. But patients with viral pneumonias are sometimes given antibiotics which do not work on viruses. Why? Because a secondary bacterial pneumonia might be occurring. The virus creates an opportunity for the bacteria which has to be treated. Patients with secondary bacterial pneumonias are often very sick and often require hospitalization.

Great content, super clear explaination! Would love to see one regarding aneurysms or atherosclerosis!

Thank you...I have recently found this page and enjoy watching,..and, find it very informative ✌

My dad passed away because of pneumocystis pneumonia. He was on cyclosporine so he could received the hemoglobin he needed because his kidneys weren’t working. I’ve always been interested in learning more about pneumonia since then.

Very specific explanation for us, non medical students/professionals/individuals. Please continue to make videos and show us what’s our organ looks like. I had an acute bronchitis before, it developed as an asthma. Now, I am not sick or anything. But sometimes, I feel like my left body is a little bit heavy. I mean my left lung is kinda heavy and it feels pain sometimes in that area. Is there a connection with this pneumonia? Or am I just paranoid. Haha. Hopefully you can discuss more about respiratory diseases next time. Peace out ✌🏻 cheers 🥂

Your guys are GREAT! I have watched other videos you have made and they are very informative. Good to know. Thanks! I have subscribed.

Just got out of the hospital with double pneumonia. Very informative video . Good to be home I was in the hospital for the past 2 weeks.

My wife had asthma, and unfortunately, she smoked. She contracted bronchitis, then it turned into pneumonia. They put her on aa ventilator, then put her out somehow, then they took a biopsy of her lungs. She passed away in hospital 27 November 2014. They said the cause of death was COPD, pneumonia, and sepsis. We were married 18 years 39 days. She was my Uber-BFF, my soulmate, the mother of my children. I miss her. JA

Who else suddenly became very aware of their breathing

my father passed away because of pneumonia , I found your video really helpful understanding how such a serious infection can cost lives of your loved ones , I still remember every moment till his last breath right underneath my eyes, what killed me the most was the non-caring medical staff that let him die without doing anything to help him even if there was time to put him under O2, and the really bad health care system here in Morocco, anyway thank you a lot for this video .

This man is great. I finally understand pneumonia...and so much more. So grateful to find someone who I can learn from. And he's cute. Looks like my son. Thank you.

Once I had a burning ‘’lump’’ in my chest for a couple of weeks. I can’t remember the rest, but at the end I coughed up a porcelain white object, that looked like cauliflower. I suspect it was white blood cells encasing whatever caused me soooo much discomfort. It looked like cauliflower because it was jello moulded from the sacks etc. it was like a snowflake and ‘’melted’’ away to a shapeless blob. The relief was instant. A miracle of nature. Didn’t have a cellphone camera back then. I suspect it was bronchial but ‘’caulifloweresque’’ seems the most apt description.

I’m finding these fascinating. Thank you! Any chance of an in-depth look on a) the larynx / vocal folds and tough etc? As a singing teacher it would be great to understand it better and be able to show my students if they wished. Also, I’m type 1 diabetic so an in-depth look at the pancreas and is mine completely useless or does it still do something?

I have subscribed to these video's.........fascinating!! I love anatomy.......good job explaining!

This is so well explained amazing how the body has a defense system

i had pneumonia in my left lung about 11 years ago, so bad, that i ended up with loculated fluid that had to be surgically removed. my left shoulder was cut open, the fluid broken up, and the subsequent protective "rind" (like an orange - and about as thick) removed. took 5 months to get over. i've also had 3X bypass, but the lung surgery was far worse.

this video in particular catches my eyes cause i have suffered from pneumonia a few different times in my life at least 3 from what i remember but thankfully its been a few years since then without coming down with it i dont know if its normal but my first time having it was the worst and i was down for about a week i remember getting really cold and shivering then soon after be really hot and sweaty and the first time was during winter i remember sitting in the hospital definetly pre covid by a few years and i had to get a blanket cause of how cold i felt as well as it being winter back then

I love these videos, clear and interesting information. Thank you guys!!

I'd be interested in a video on asthma, in addition to that video on bronchitis you mentioned and are hopefully doing :)

This is really interesting to me. I had pneumonia last year in my right lung all three sections of it. 🤷🏻‍♀️ no idea what type because my doctor at the time didn’t send me to get imaging but antibiotics was what got rid of it. Almost ended up in hospital though and took so long to get over. So it’s really interesting watching this video and knowing more about it.

I developed pneumonia 7 years ago after a personal loss within three days of the first symptoms my right lung shut down completely and was non functioning. Absolutely terrifying . I had both a bacterial infection and a viral pneumonia which was why it was so bad. I coughed blood for around three or four months after and six months after the hospitalization I developed a blood clot in the exact same spot so it was a pretty rough year. Thankfully I got through it . I’m 37 now and even though I’ll be on meds for the rest of my life it could have been so much worse and i know how lucky I am to be here.

Great video, you answered a lot of questions and gave me a great basic education of the subject, thank you

I learned so much about the lungs and pneumonia! Thank you.

Very informative as usual. Thanks for this too. Can you do one on PCP - Pneumocystis pneumonia ?

I was a firefighter paramedic, this helps understand why you are giving meds, what is actually happening during there crisis. Thanks

I really liked the way you explain things along with showing the real part.

I had severe phneumonia when I got covid.. it was pretty scary.. I thought I will never be able to run again because I was gasping for air from simple tasks even after being discharged. I remember they gave me blood thinners and tucilizumab

Very cool description! I've always been interested in how the human body works and your series are a great way to understand the processes. I want to learn about the amazing complexity of DNA and how it works someday, I know a little bit but it's a bit heavy and hurts my brain.

you're videos are great. thank you for what you do.

Wow, you have a great way of explaining, I understood it all. Thank you.

Me: Starts watching the video Also me: Coughs immediatly everytime they mention anything going down into the lungs.

I still remember my anat lab days,we were not supposed to use gloves while touching the cadavers and then the whole day our fingers had that pungent formalin odour.Nostalgic😊

I am learning so much from you, I wish you were around when I was younger too. Last night at the dinner table a pop song came on the tv and my daughter said, this would be a great song to do CPR to. so we got chatting about it and I found myself telling her about your video on the speed at which you should do chest compressions, even my husband listened with interest. so thankyou you might well have given us the knowledge to save a life.

I'm a nurse for 20 years and I find u very informative 👌😊 thank u

12 years ago, Rhode Island Hospital let me sit in their waiting room for 8 hours with pneumonia, bleeding from the throat due to coughing. Sat there for 8 hours until I gave up seeing a doctor and went home. Lungs were damaged and now I weeze when on my back making sleeping impossible for the rest of my life. THANK YOU RHODE ISLAND HOSPITAL!
