BIOD33H3 Lecture Notes - Lecture 1: August Krogh, Comparative Physiology, Torpor
Comparative meaning using comparison animals that aren"t rats or mice when comparing it with a human. August krogh principle: for every question in biology, there is an ideal model system. 3 types of comparative physiology: mechanistic physiology understand how anatomy, cell components work to give bodily functions. Evolutionary physiology compare evolution with different animals by using similar anatomy features. Environmental physiology trying to understand how environment, climate, habitat affect animal function. We tend to think that any characteristic an animal has because it gives them some sort of adaptive significance. Mostly, this is the case, but not always. Example: when people go to high altitude high altitude = low oxygen breathing increases. This happens to all animals, and not just humans. Other examples can be high salt-concentrated places or hot places: other one is development change as an organism develops throughout its life, it"s physiological parts change as well.
