1. Anatomy is the study of the structure and shape of the body and it's parts; Physiology is the study of how the body parts and its function; anatomy studies the shapes of muscles and physiology studies how they work together to make you smile.

2.Atoms-Oxygen; Cells- skin; tissue- epithelial in skin; organ- stomach; organ system- digestive system; organism- a person.

3.Integumentary- protects deeper tissue from injury- skin, hair, nails and sweat glands.

4.Organization; metabolism and excretion; movement and response to stimuli; developement; reproduction; homeostasis.

5. Nutrients; Oxygen; Water; Heat to maintain body temperature; Pressure for breathing and filtering blood.

6. The tendency of an organism to maintain a stable internal environment: all life processes and metabolic reactions maintain homeostasis; homeostasic mechanisms ar regulated...
