Introduction to Physiology and Homeostasis - Concept of Homeostasis

3 important questions on Introduction to Physiology and Homeostasis - Concept of Homeostasis

What is the internal environment and another term for it?

a watery fluid that surrounds the cells that through which they make life-sustaining exchanges
extracellular environment

What is homeostasis and why is it important?

homeostasis is the maintenance of the dynaminc state of the internal environment within a range that supports the body cells sustain life. It means controlling the chemical composition and physical state of this watery medium through compensatory physiological responses.


its important because body cells can live and function only when the ECF/IE is compatible with their survival; thus, the chemical composition and
physical state of this internal environment must be maintained
within narrow limits.

What is the special relationship between homeostasis and body cells/systems?

Homeostasis is essential for the survival of each cell, and each cell, through its specialized activities as part of a body system, helps maintain the internal environment shared by all cells
