Blood is pumped to the various places of the body by a process known as the cardiac cycle. Oxygen depleted blood returns from the body to the right atrium of the heart by two large veins called vena cavae.
Written By: Pulmonary circulation, system of blood vessels that forms a closed circuit between the heart and the lungs, as distinguished from the systemic circulation between the heart and all other body tissues.
Pulmonary circulation. The pulmonary circulation becomes totally separate in crocodilians, birds, and mammals, when the ventricle is divided into two chambers, producing a four-chambered heart. In these forms the pulmonary circuit begins with the right ventricle, which pumps deoxygenated blood through the pulmonary artery.Pulmonary Circuit Diagram Image Diagram - Chart - diagrams and charts with labels.
