Study Notes
Introduction to Physiology
- Physiology is the study of how different body systems function, their mechanisms, and factors affecting these functions.
Structure of the Human Body
- The human body is organized into systems, organs, tissues, and cells.
- Cells are the basic structural unit.
- Tissues are groups of similar cells.
- Organs are groups of different tissues working together.
- Systems are groups of different organs that work together to perform a specific function.
The Cell
- A cell is composed of a cell membrane and cytoplasm.
- Inside the cytoplasm are:
- Nucleus: Contains the genetic material (DNA).
- Mitochondria: Responsible for energy production within the cell.
- Golgi apparatus:
- Lysosomes: Contain proteolytic enzymes.
- Ribosomes: Responsible for protein synthesis.
- Centrosome: Responsible for cell division.
- Rough and smooth endoplasmic reticulum.
