Chemoreceptors in the aortic arch, the carotid bifurcation and the brainstem send information about the partial pressures of oxygen and carbon dioxide and the pH of the blood (and therefore of the tissues of the body) to the respiratory centres in the brainstem. The respiratory centres regulate the movements of the diaphragm, the intercostal muscles and accessory muscles of ventilation to drive inspiration and expiration. The chemoreceptor reflex describes how changes to the composition of the blood lead to changes in ventilation.

Honestly. I havent been in school since hs 10 years ago and I still catch his videos because of how good he is at teaching and explaining the full picture 😅

Excellent breath sounds to demonstrate the role of the chatelier's principle, carbonic anhydrase and blowing off CO2 in the chemoreceptor reflex. Well done Sam the physiologist.

These reflexes are so interesting. So much on autopilot in the body.

Your videos are a blessing! I'm studying behavioral neuroscience and it's extremely difficult trying to make sense of it all with only a textbook. Your videos really help to give a more complete picture of what's going on. Thank you a thousand times, please keep making these excellent vids!

I feel like a complete ignoramus....but captivated by your classes...we are without dought amazing Sam....such a mind blowing great job you do, so inspiring for all of us, and our young medics....all the best to students...we sure are complicated .....❤

Just started the neuro block in school so this video was perfect timing, thanks Sam for elaborating on the these reflexes during my dinner break. Hope the Baldur's Gate 3 run is going well too!

Excellent Review!

Brainstem : "Ph and CO2 within acceptable range. Everything a-okay.". Cerebrum : "Feeling a bit tired here. Better lay down for a moment.". *dies of carbon monoxide poisoning* Post-mortem Cerebrum : "I need a more modern alarm system...".

Sir, I have a question... "All reflex actions are involuntary in nature but all involuntary actions are not reflexes". Is it correct? When does an 'involuntary' action become a 'reflex' action? Hope you mention it in your upcoming videos as well!!
