Name the upper chambers of the heart and their functions.
RIGHT ATRIUM: Receives oxygen-poor blood from the veins of the body.
LEFT ATRIUM: Receives oxygen-rich blood from the lungs via the pulmonary veins.
Name the lower chambers of the heart and their functions.
RIGHT VENTRICLE: Pumps oxygen-poor blood to the lungs.
LEFT VENTRICLE: Pumps oxygen-rich blood to the body.

Blood vessels which carry blood to the heart.
Blood vessels which connect arteries and veins.
Blood is composed of four different parts, each having its own function.
Name the four parts and their functions.
1. Red Blood Cells: Carry oxygen to organs, carbon dioxide away from organs, and gives blood its color.
2. White Blood Cells: Combat infection.
3. Platelets: Clot formation.

1. Sensory: Nerves which carry information from the body to the spinal cord and brain.
2. Motor: Nerves which carry information from the brain and spinal cord to the body.
Three functions of the Skeletal System.
1. Gives the body shape.
2. Protects the vital internal organs.
3. Provides for body movement.
Name the five sections of the Spinal Column.
1. Cervical(neck)
2. Thoracic(upper back)
3. Lumbar(lower back)
4. Sacral(back wall of the pelvis)
5. Coccyx(tailbone)
Three types of muscles.
1. Voluntary(skeletal)
2. Involuntary(smooth)
3. Cardiac
Three layers of skin.
1. Epidermis
2. Dermis
3. Subcutaneous Layer
Three functions of the skin.
1. Protection from the environment, bacteria and other organisms.
2. Temperature regulation.
