Definition of Physiology
- Physiology is the complement to anatomy and is concerned with the function, rather than the form, of structures in the body.
- It is the study of the physics and chemistry of structures, as well as how they work together to provide a specific function.
- Homeostasis is the steady internal state which the body maintains.
- Physiology is concerned with how structures in the body function to maintain homeostasis.
Relationship with Anatomy
- Anatomy and physiology cannot be studied in isolation.
- Instead, they must be taken together, as two parts of the same puzzle.
- For example:
- To understand how the spine functions, we must look at the structure of the bones.
- But to understand the structure of the bones, we must look at how it functions.
