Identify how anatomical left is different from you left.
Anatomical left is on the right side of the body because the body is facing forward.
List and define the major planes that are used to divide the body into parts.

A helpful diagram of the planes & direction of the body
Discuss how a person's body type might influence their their health risks.
The knowledge of physique can provide professionals w/ vital info useful in such areas as disease screening procedures, programs designed to identify individuals at risk for certain diseases.
List the basic components of every feedback control system.
Integrating or control center
Effector mechanism
Explain the mechanism of action of negative & positive control systems.
Negative feedback control system are inhibitory, while positive feedback systems are stimulatory & does not help the body maintain a stable condition????
Specific chemical messengers.
The name used to describe the study of the body that consider groups of organs that have a common function.
Systemic anatomy.
Combinations of atoms forming larger chemical aggregates.
