Introduction to Anatomy and Physiology

2. Anatomy Examines the morphology (or structures) of the body.
Form and organization of organisms.

3. Physiology Examines the functions of the body. What do structures do?
Why do structures do the things they do?

4. Anatomy and Physiology
Anatomy and physiology are interconnected and depend on one another for life to exist. (Structure is related to function.)

5. Examining Organisms as Parts to Whole
Atoms
Building blocks of matter.
Composed of subatomic particles.
Form molecules which group together to form macromolecules.

6. Examining Organisms as Parts to Whole
Cells
Basic units of structure and function in organisms.
Vary in characteristics such as size and shape.
All cells contain organelles that carry out specific functions.
Remember that organelles are made out of large molecules such as proteins, carbohydrates, lipids, and nucleic acids.
Most cells have a complete set of genetic instructions but only use a subset of the instructions, which allows the cell develop specialized functions.

7. Examining Organisms as Parts to Whole
Tissues
Masses or layers of cells that all have similar functions.

8. Examining Organisms as Parts to Whole
Organs
Groups of similarly functioning tissues.

9. Examining Organisms as Parts to Whole
Organ Systems
Groups of organs working together to perform specific functions.

10. Examining Organisms as Parts to Whole
Groups of interacting organ systems.
