Study Notes
Introduction to Human Physiology
- Physiology is the study of the functions of the human body at different levels, from cells to organs and systems.
- Metabolism encompasses all the chemical processes occurring in the organelles of cells.
- Anabolism involves the use of energy to produce chemical substances, while catabolism is the breaking down phase of metabolism, yielding energy.
- Examples of anabolism include glycogenesis (synthesis of glycogen) and gluconeogenesis (synthesis of glucose), while glycolysis represents catabolism (glucose breakdown).
- Homeostasis refers to the state of steady internal conditions maintained by living systems, such as body temperature and blood glucose levels.
- Key elements in physiology include blood glucose level homeostasis and body temperature homeostasis (thermoregulation).
- Feedback mechanisms, such as negative feedback, play a crucial role in maintaining homeostasis by opposing and reversing changes in the body, such as temperature or blood pressure.
