This course covers general physiological concepts such as homeostasis, control theory, and system analysis. It also takes a detailed view of how these general principles apply specifically to various physiological systems in humans and other mammals in some cases. Systems such as respiration, circulation, digestion, metabolism, thermoregulation, and excretion are studied at cellular, tissue and whole system levels. In cases where form is especially critical to function, anatomy is also covered, although there is no human dissection. This course cannot be taken for credit if the student has already received credit for BIOL 314. Prerequisite: BIOL 233 and (CHEM 120 or CHEM 150).
