Pulmonary circulation
The pulmonary circulation is a circuit of blood circulation in the cardiovascular system, serving exclusively the lungs, where red blood cells pick up oxygen and release carbon dioxide during respiration.
Deoxygenated blood is pumped out of the right ventricle of the heart into the pulmonary trunk, then to the pulmonary arteries and into the lungs. Via pulmonary veins, oxygenated blood is then drained into the left atrium. Blood is then circulated in the systemic circulation.
