Overview
This lecture introduces the basics of Anatomy and Physiology (A&P), outlining its importance, key themes, and foundational terminology.
Isotopes are elements with the same atomic number but different mass number
What is Anatomy & Physiology?
- Anatomy is the study of body structure and the relationships among body parts.
- Physiology examines how the body parts function and work together to maintain life.
- A&P are interrelated fields essential for understanding how the human body works.
Levels of Organization in the Body
- The body is organized into levels: chemical, cellular, tissue, organ, system, and organism.
- Each level builds upon the previous one for increasing complexity and function.
Major Themes in A&P
- Homeostasis is the process by which the body maintains a stable internal environment.
- Structure determines function: the shape of a body part influences how it works.
Scientific Approach in A&P
- The scientific method is used to study A&P through observation, hypothesis, experimentation, and conclusion.
- Evidence-based practice applies scientific findings to healthcare and medicine.
Key Terms & Definitions
- Anatomy — the study of body structures
- Physiology — the study of body functions
- Homeostasis — maintenance of stable internal conditions
- Organism — an individual living entity
Action Items / Next Steps
- Review definitions of anatomy and physiology.
- Study the levels of body organization and examples of each.
- Prepare for questions on homeostasis principles.
