The ---- is above the heart and carries de- oxygenated blood from the head and arms to the right atrium of the heart.

Superior vena cava

Inferior vena cava

The ---- is the largest vein of the body. It carries de- oxygenated blood back from the lower part of the body to the right atrium of the heart. This blood is carrying carbon dioxide.

Mitral bicuspid valve

Mitral valve

---- is the process of inhaling oxygen into the lungs, and exhaling carbon dioxide. That process includes the ventilation of the lungs and the exchange of air in the lungs and blood within the capillaries of the alveoli of the lungs.

External Respiration

Internal Respiration

The ---- artery leads downward through the diaphragm and chest, and into the abdomen. About 1/5 to 1/3 of the blood passes through the ---- into the kidney. The kidney is a filter, and takes some water and waste products out of the blood.

Aorta

Alveoli

Arteries

The peak pressure occurs during the heart's contraction is called ---- While the minimum pressure occurs between contractions when the heart expands and refills is called ---- This pressure variation within the artery produces a pulse.
