Answer»

The circulatory system is made up of theheart,bloodandblood vesselsknown asarteries,capillariesandveins.

The heart pumps blood throughout your body through the blood vessels. Blood delivers oxygen and nutrients to cells and carries away carbon dioxide and other waste materials.

Pulmonary circulation: This part of the cycle carries oxygen-depleted blood away from the heart, to the lungs, and back to the heart.

Systemic circulation: This is the part that carries oxygenated blood away from the heart and to other parts of the body.

Coronary circulation: This type of circulation provides the heart with oxygenated blood so it can function properly.
