2023年10月30日 · 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!

2024年12月9日 · 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.

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 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.

2022年9月19日 · 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.

2023年8月26日 · The pulmonary circulation carries deoxygenated blood away from the heart to the alveoli to undergo gas exchange and returns oxygenated blood back to the heart. This article considers the functions of both the bronchial and pulmonary …

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.

2023年5月1日 · 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 primary function of pulmonary circulation is to facilitate gas exchange between the blood and the lungs. As blood passes through the pulmonary capillaries, it picks up oxygen from the alveoli and releases carbon dioxide.

During fetal life, the pulmonary circulation is a low flow, high-resistance circuit. With transition to postnatal life, the pulmonary vasculature dilates, accommodating the entire cardiac output (CO), with high blood flow maintained at low intravascular pulmonary arterial pressure (P PA).
