The circulatory system is an organ system that permits blood and lymph circulation to transport nutrients, compound for blood vessels.

The blood vessels are the part of the circulatory system that transports blood throughout the body. There are three major types of blood vessels: the arteries, the capillaries and the veins.

Blood vessels that carry blood away from the heart. Most arteries carry oxygenated blood.

This are the smallest of the blood vessels and serve as the connection between the arterial and venal systems.

Blood vessels that carry blood toward the heart. Most veins carry deoxygenated blood from the tissues back to the heart; except by the pulmonary and umbilical veins, both of them carry oxygenated blood to the heart.

Consist of plasma, red blood cells, white blood cells, and platelets.

The hemoglobin is the protein in the blood that carries oxygen from the respiratory organs to the rest of the body.
The hemoglobin molecule is the primary transporter of oxygen, also is the hemoglobin that makes blood red.

Pumps oxygenated blood to the body and deoxygenated blood to the lungs. In the human heart there is one atrium and one ventricle for each circulation, and with both a systemic and a pulmonary circulation there are four chambers in total: left atrium, left ventricle, right atrium and right ventricle.

Coronary circulatory system provides a blood supply to the myocardium (the heart muscle). It arises from the aorta by two coronary arteries, the left and the right, and after nourishing the myocardium blood returns through the coronary veins into the coronary sinus and from this one into the right atrium.

Systemic circulation is the circulation of the blood to all parts of the body except the lungs.

The pulmonary circulatory system is the portion of the cardiovascular system in which oxygen-depleted blood is pumped away from the heart, via the pulmonary artery, to the lungs and returned, oxygenated, to the heart via the pulmonary vein.
