Which Concept is the Defining Feature of the Discipline of Physiology

Question

Which concept is the defining feature of the discipline of physiology?
A)Descent with modification
B)Homeostasis
C)Evolution
D)Equilibrium
E)Differentiation

Accepted Answer

Homeostasis is the defining feature of physiology, as it is the study of the processes and mechanisms by which organisms maintain a stable internal environment in the face of changing external conditions. This involves understanding the functioning of various organ systems, as well as the interactions between them, and how they work to regulate key physiological variables such as temperature, pH, and fluid balance. While concepts such as descent with modification, evolution, equilibrium, and differentiation may be relevant to physiology in certain contexts, homeostasis is the central organizing principle that underlies the discipline as a whole.
