Study Notes
Definition of Physiology
- Physiology focuses on the normal biological function of living organisms.
Levels of Structural Organization in the Human Body
- Organized hierarchically from simple to complex:
- Chemicals: Atoms form molecules.
- Cells: Fundamental units that perform life functions.
- Tissues: Groups of similar cells working together.
- Organs: Structures composed of different tissues.
- Organ Systems: Groups of organs that perform related functions.
The Chemical Level
- The human body is built from atoms that combine to form molecules.
- Chemical reactions occur among atoms and molecules, which are regulated by physiological processes.
Cells
- Cells are the most basic living units capable of performing all essential life activities.
Tissues
- Tissues consist of organized groups of similar cells.
- Collaboration among cells is crucial, as individual cells cannot efficiently accomplish tasks alone.
