Human Anatomy and Physiology: Core Framework
- Anatomy is the study of the structure, shape and arrangement of body parts.
- Physiology is the study of how those body parts work.
- The human body is organised as:
Cells → Tissues → Organs → Organ systems → Organism
- Different organ systems work together to maintain homeostasis, meaning a stable internal environment such as normal body temperature, blood glucose, water balance, pH and blood pressure.
