What is a difference between systemic and pulmonary circulation

The difference between systemic and pulmonary circulation is the Systemic circulation carries the blood between to the heart and body and the pulmonary circulation carries blood between the lungs and the heart.

Explanation:

Circulation of blood is of two types:

The systemic circulation and The pulmonary circulation.

The Systemic circulation carries the oxygenated blood from heart to the body through the arteries (aorta) and also carries back the deoxygenated blood from the body to the heart through veins (superior vena cava) and pulmonary circulation carries deoxygenated blood to the lungs from the heart and from the lungs to the heart.

In Pulmonary circulation the pulmonary artery is used to carry the deoxygenated blood to the lungs and the pulmonary vein is used to carry oxygenated blood to the heart from the lungs.
