The parts of the cardiovascular system include the heart, which is the organ that pumps the blood, and a network of blood vessels:
Arteries: The blood vessels that take blood away from the heart
Veins: Blood vessels that return blood to the heart
Capillaries: Very small vessels that lie between the arteries and veins
The portal vein and its tributaries carry blood from parts of the digestive system to the liver before reaching the heart.
The heart is a muscular pump with four chambers inside: the right and left atria and the right and left ventricles. Those four chambers allow the heart to pump blood through the following two circulatory pathways:
Systemic circulation: Takes oxygen-rich blood to the tissues and organs of the body
Pulmonary circulation: Takes oxygen-depleted blood to the lungs and oxygen-rich blood back to the heart again.
1. The left ventricle of the heart receives oxygenated blood from the left atrium.
2. Blood is ejected from the left ventricle into the aorta, a large artery.
The ascending aorta sends blood to the upper thorax, upper extremities, neck, and head.
The descending aorta sends blood to the lower thorax, the abdomen, the pelvis, and the lower extremities.
3. The blood leaves the ascending and descending parts of the aorta and enters a network of systemic arteries that run to all places of the body.
4. Blood passes from the smallest arteries (called arterioles) into the
