TEMPERATURE REGULATION in the HUMAN BODY by Professor Fink 

the man, the legend, the prodigy best known as, The Professor.

i cant imagine having that projector shine me in the eyes like that! great video, thank you.

Best teacher I’ve ever come across

I always loved ur vedios ,,lots of thanks from indian occupied kashmir

extremally thankful for your videos!!!

Thank you

Great source of information. Since moving down to New Orleans, I struggle in the high humidity. My heart pounds, my skin is flushed and my hands swell up every time I go outside. Now I believe it's because I don't sweat. My body is having trouble with heat loss I guess. What controls sweating?

Wow u the best!

Please doctor in hypothermia which branch of autonomic nervous system is stimulated? And what is do to blood vessels and sweat glands???

Why do we have high probability of sneezing when we feel cold? Is there any explanation to it or under which discipline is this?

Hey Dr fink! When you talk about acclimatization. In theory would working out in the cold make you lose any significant more weight? People always like to train when its hot for this effect, but the increase in thyroxin and epinepherine make me think the opposite. Further I am in nursing school. Im trying to wrap my mind around how vital signs are effected in hypothermic conditions. They say all your vital signs go down. I would think because of the vasoconstriction BP would be higher, Heart rate would be faster, and Lungs would be slower to generate the most heat. they actually say your meabolic rate decreases because you move less.....What i am thinking is it all depends on the degree of your temp. Sorry i know this is a potentially long answer but i really appreciate how you explain things. You should make textbooks! People would be so much smarter if they were written in a spoken word type of format.

Great video Professor Fink! One question though, as far as I know, the nervous and endocrine systems acting together to maintain homeostasis. But is it true that homeostasis always involves the interaction between these two systems? It seems to me that regulating blood CO2 level and maintaining a normal body temperature do not require hormones... Thank you!

If my room is cold because is not heated and my temperature is 35.7 what can you say about this

Could you please tell me the name of the book that you were talking about?

Sir i want the clear notes of what you take a seminar ..plz sir

How can i get access to the animation you show? Thank you.

Did you see that? "We open up our Physiology book... And we start sleeping" LOL.

While the information on physiological responses was quite valuable, you have misrepresented the fundamental heat transfer phenomena quite a few times. Radiative heat loss is not to the air itself, but rather an electromagnetic dissipation of heat "light" (in the IR spectrum). This phenomena is why you can feel the heat of a fire in a fireplace, even if the energy in the air itself is carried up the chimney. Also, humans can still dissipate heat in an environment over 100F, as the evaporation that results from perspiration will allow the local temperature to go below that of the ambient environment. As you note around 14min in, it takes a great deal of energy to more liquid water (1000 kg/m^3) to vapor (~1 kg/m^3), and this can drop the local temperature all the way down to the "dew point", which is below ambient temperature (so long as you are below 100% relative humidity). This same energy goes to creating vapor in your exhalation, which accounts for the majority of energy lost through respiration undermost conditions. I appreciate the great physiological background, but I hope you can include the appropriate definitions of the heat transfer phenomena in future lectures to ensure your student aren't misled.

Hello sir,Can you please explain if temperature regulation is a negative feedback mechanism or is it a feedforward mechanism..confused a lot

‘Anaesthesia, Amnesi Death-or more precisely, our own death-falls outside the scope of our experience and as such remains unknowable. We can only confirm our intuition that we are alive ‘for ourselves’ through the lived experience of our existence. And the one thing that allows us to establish this sense of ourselves as living beings is the fact of our boundedness. None of the many attempts to establish in generic terms what it is to be alive are ever wholly satisfactory. Reproduction, homeostasis, and self-preservation are commonly cited as invariant properties of living organisms, but these functions only make sense in terms of the interiority of an organism. The integrity of a living being immediately implies its circumscription in space. For no organism can sustain itself without a boundary that gives it a form and allows it to interface with the world outside of it. This boundary, this spatial limit, is something I simultaneously incarnate and grasp through my body; it is effectively all that I am. But this bodily limit is also something I must consign to secrecy each time it reveals itself, plunging it over and over again into obscurity so that a dream of my infinite existence can be perpetuated and expanded. Nevertheless, at some point I must reconcile myself to the fact that the first thing I am conscious of, as a living being, is the fact that I have limits. The limit of the surface of a skin that brings me pleasure and pain; the limits of my growth, my flexibility, my reach; the limits of my strength, my abilities, and my energy; the limits of my senses.’

Adrenaline is released when body temperature is low, or blood volume is reduced eg. in shock This causes peripheral vasoconstriction to maintain blood flow to vital organs and muscles. But adrenaline also triggers sweating, and sweat glands are controlled by the sympathetic nervous system. This seems counterproductive.

Why dont you cover NCLEX professor? I think you should think about including NCLEX in your lectures.

Didn't mention the use of conscious control over body temp.
