Study Notes
Physiologists' Approach
- Physiologists explain how the body works.
- They view the body as a machine whose mechanisms of action are explained in terms of cause-and-effect sequences of physical and chemical processes.
Cellular Functions
- Most cells can reproduce, except for nerve cells and muscle cells.
- Homeostasis is the maintenance of a relatively stable internal environment, which is essential for the survival of each cell.
Contributions to Homeostasis
- Each cell, through its specialized activities, contributes to the maintenance of the internal environment shared by all cells as part of a body system.
Endocrine System Function
- The endocrine system regulates activities that require duration rather than speed.
Integrated Body Function
- The body is a coordinated whole, with each system providing its own special contributions.
- The functioning whole is greater than the sum of its separate parts.
