Structure and function of the heart

Cardiac output is a measure of the rate of blood flow through the heart and its associated blood vessels. Changes of pressure allow the blood to flow through the cardiac cycle. This is controlled by the cardiac conducting system and regulated by the medulla via the autonomic nervous system.

Blood vessels leading into and out of the heart

There are four main blood vessels that take blood into and out of the heart.

  1. the aorta is the largest artery in the body. It carries oxygenated blood away from the left ventricle to the body
  2. the vena cava is the largest vein in the body. It carries deoxygenated blood from the body back to the heart
  3. the pulmonary artery carries deoxygenated blood away from the right ventricle to the lungs
  4. the pulmonary vein returns oxygenated blood from the lungs to the heart
Arteries carry blood away from the heart (except for the pulmonary artery).

Arteries carry oxygenated blood away from the heart (except for the pulmonary artery which carries deoxygenated blood away from the right ventricle to the lungs).

The main artery is the aorta.

The main vein is the vena cava.

Which is the only artery that carry deoxygenated blood?

The pulmonary arteries are a pair of blood vessels that transport deoxygenated blood from the heart to the lungs. The pulmonary arteries are considered ''great vessels'' and are unique because they are the only arteries in the body that carry deoxygenated blood.

What carries deoxygenated blood except?

All the veins carry deoxygenated blood except the pulmonary vein. It carries oxygenated blood from lungs to the heart.
