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 away from the heart.

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.
4. Plasma: The fluid portion, carries blood cells, nutrients and waste products. - Two primary components of the nervous system.
-
1. Central Nervous System
2. Peripheral Nervous System - Two primary components of the Central Nervous System(CNS).
-
1. Brain
2. Spinal Cord - Two main types of nerves that comprise the Peripheral Nervous System.
-
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.
3. Sensing touch, pressure, pain, Heat and cold.
