The physical form of an organ or tissue is inextricably linked to its physiological role. For example, the thin walls of lung alveoli facilitate rapid gas exchange. 2. Major Physiological Systems Nervous System:
Unlike comparative anatomy (which focuses on structure), physiology emphasizes : how systems operate, regulate, and adapt to maintain life. fisiologia animal
