Hey guys ! Today we're looking at gas exchange in humans. Most of the topic is straight forward except for the section about how we breath in and out. For some it may be quite easy, but for some others it may be rather confusing. I've tried my best to explain to you how it works but if you still have further questions please comment below. Best of luck guys !
