The pulmonary circulation pumps blood from the heart to the lungs for oxygenation and back to the heart. Learn about its anatomy and function at Kenhub!
The pulmonary circulation is a division of the circulatory system in all vertebrates. The circuit begins with deoxygenated blood returned from the body to the right atrium of the heart where it is pumped out from the right ventricle to the lungs.
Pulmonary circulation is the system of transportation that shunts de-oxygenated blood from the heart to the lungs to be re-saturated with oxygen before being dispersed into the systemic circulation. Deoxygenated blood from the lower half of the body enters the heart from the inferior vena cava. In contrast, deoxygenated blood from the upper body is delivered to the heart via the superior vena ...
Pulmonary circulation moves blood between the heart and the lungs. It transports deoxygenated blood to the lungs to absorb oxygen and release carbon dioxide. The oxygenated blood then flows back to the heart. Systemic circulation moves blood between the heart and the rest of the body.
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. Learn more about pulmonary circulation in this article.
Pulmonary Circulation is a peer-reviewed open access journal which focuses on increasing survival rates for pulmonary hypertension and other pulmonary vascular diseases worldwide, and developing new therapeutic approaches for the diseases.
Pulmonary circulation is the movement of blood from the heart to the lungs for oxygenation, then back to the heart again. Oxygen-depleted blood from the body leaves the systemic circulation when it enters the right atrium through the superior and inferior venae cavae. The blood is then pumped through the tricuspid valve into the right ventricle.
Pulmonary circulation includes a vast network of arteries, veins, and lymphatics that function to exchange blood and other tissue fluids between the heart, the lungs, and back. They are designed to perform certain specific functions that are unique to the pulmonary circulation, such as ventilation and gas exchange.
The pulmonary circulation accommodates the entire cardiac output, maintaining high blood flow at low intravascular arterial pressure. As compared with the systemic circulation, pulmonary arteries have thinner walls with much less vascular smooth muscle and a relative lack of basal tone.
The pulmonary arteries and the pulmonary veins are the vessels of the pulmonary circulation; which means they are responsible for carrying the oxygenated blood to the heart from the lungs and carrying the deoxygenated blood from the heart to the lungs.
