Gross anatomy
Study of structures that can be seen with the naked eye
Microscopic anatomy
deals with structures too small to be seen with the naked eye
Relationship between anatomy and physiology
structure determines function
Necessary Life Functions
1. Maintaining boundaries
2. Movement
3. Responsiveness
4. Digestion
5. Metabolism
6. Excretion
7. Reproduction
8. Growth
Survival needs
nutrients, oxygen, water, normal body temperature, appropriate atmospheric pressure
Homeostasis
A tendency to maintain a balanced or constant internal state
How homeostasis is maintained
1. Receptor responds to change
2. Control center decides what to do
3. Effector provides response to stimulus
Negative feedback systems
reverses a change in a controlled condition
positive feedback system
1.Childbirth
2. Lactation
3. Blood clotting
Diaphragm
Large, flat muscle that separates the thoracic and abdominopelvic cavities
anatomical position
erect, feet forward, arms at side with palms facing forward, head facing forward
