The blood vessels of the pulmonary circulation are the pulmonary arteries and the pulmonary veins. A separate circulatory circuit known as the bronchial circulation supplies oxygenated blood to the tissue of the larger airways of the lung.
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.
1 maj 2023 · Three zones of pulmonary blood flow can be delineated based on the pulmonary capillary pressure (Pcp)and the pulmonary alveolar air pressure (Ppac). Zone 1 : The Pcp is always less than the Ppac here, and there is no blood flow in the pulmonary capillary bed during any phase of the cardiac cycle.
19 wrz 2022 · 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.
26 sie 2023 · 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 circulation and their special adaptations.
pulmonary circulation: The part of blood circulation which carries oxygen-depleted blood away from the heart, to the lungs, and returns oxygenated blood back to the heart. systemic circulation: The part of blood circulation that carries oxygenated blood away from the heart, to the body, and returns deoxygenated blood back to the heart.
