Study Notes
What is physiology?
- Physiology is the study of how the human body works
- It describes the chemistry and physics behind basic body functions, from how molecules behave in cells to how systems of organs work together
- Helps understand what happens in a healthy body in everyday life and what goes wrong when someone gets sick
Types of physiology
- Medical physiology: Focuses on human physiology
- Animal physiology: Covers animals' functions
- Plant physiology: Studies plant functions
- Cell physiology: Focuses on cell functions
- Comparative physiology: Compares functions across different species
Definition of physiology
- Physics + Biology + Chemistry = Physiology
- The branch of science dealing with the basic functions of living organisms
- Science of "function"
- Physiological: "Normal"; not pathological; properties belonging to normal functions of tissues, organs or body
5 subdivisions of physiology
- Neurophysiology - functional properties of nerve cells
- Endocrinology - hormones and how they control functions
- Cardiovascular physiology - how the heart and blood vessels function
- Respiratory physiology - how the lungs function
- Renal physiology - how the kidneys function
