In the pulmonary loop, deoxygenated blood exits the right ventricle of the heart and passes through the pulmonary trunk. The pulmonary trunk splits into the right and left pulmonary arteries. These arteries transport the deoxygenated blood to arterioles and capillary beds in the lungs.

Oct 30, 2023 · Two pulmonary veins emerge from the hilus of each lung, and each pulmonary vein receives blood from 3-4 bronchial veins apiece before draining into the left atrium. The pulmonary veins are fixed to the pericardium travel alongside the pulmonary arteries.

Figure 20.5.2 – Pulmonary Circuit: Blood exiting from the right ventricle flows into the pulmonary trunk, which bifurcates into the two pulmonary arteries. These vessels branch to supply blood to the pulmonary capillaries, where gas exchange occurs within the lung alveoli.

Oct 30, 2023 · The pulmonary veins are large valveless vessels that carry oxygen-rich blood from the lungs to the left atrium of the heart. These veins are unique in that, unlike other veins of the body which transport deoxygenated blood, the pulmonary veins carry oxygenated blood.

Arteries. From the right ventricle, blood is pumped through the semilunar pulmonary valve into the left and right main pulmonary artery (one for each lung), which branch into smaller pulmonary arteries that spread throughout the lungs. [3][6] Development. The pulmonary circulation loop is virtually bypassed in fetal circulation. [7] .
Jun 2, 2020 · The now oxygen-rich blood flows from the lungs back to the heart through the pulmonary veins, flooding into the left atrium. Each lung has two large pulmonary veins, where all four lead directly into the left atrium.
Sep 19, 2022 · Once fully saturated with oxygen, the blood is transported via the pulmonary vein into the left atrium, which pumps blood through the mitral valve and into the left ventricle. With a powerful contraction, the left ventricle expels oxygen-rich blood through the aortic valve and into the aorta.
