Anatomy and Physiology

Two important Concepts in Anatomy and Physiology

Structure underlies function Homeostasis

Structure Underlies Function

It is important to note that the design of the structures of the anatomy and physiology of the body are designed with purpose and not by accident.The structures are designed in such a way as to maximise the efficiency of the function the structure is designed to do.

Homeostasis

Homeostasis is the maintenance of a relatively stable internal environment, despite external changes.
