where does blood go when it leaves the pulmonary artery?
the pulmonary vein
in an anatomically correct heart the right atrium and right ventricle are working together to supply blood to the pulmonary artery, similarly to how the left atrium and the left ventricle work simultaneously to supply blood to the aorta. during the process of the heart contracting and releasing the right atrium and left atrium contract at the same time, while the left ventricle and right ventricle relax. in opposition, when the left atrium and right atrium are relaxed the left ventricle and right ventricle contract pushing blood to either the aorta or pulmonary artery. in an anatomically correct heart the atria are smaller than the ventricles. the ventricles include more muscle in order to push high quantities of blood throughout the body. normal blood flow throughout the heart begins at the superior vena cava coming from the upper half of the body and the inferior vena cava coming from the lower half of the body. next blood will be in the right atrium and will flow uninterrupted through the tricuspid valve through to the right ventricle. the blood from the right ventricle should go to the pulmonary artery via the pulmonary valve.the blood from the pulmonary vein enters the left atrium, then flows through the mitral valve to the left ventricle. after the left ventricle is filled with blood the aortic valve opens allowing blood to go through, which the blood then enters the aorta and goes to the rest of the body.

pulmonary artery









































a pulmonary artery is an artery in the pulmonary circulation that carries deoxygenated blood from the right side of the heart to the lungs. the largest pulmonary artery is the "main pulmonary artery" or "pulmonary trunk" from the heart, and the smallest ones are the arterioles, which lead to the capillaries that surround the pulmonary alveoli.

in order of blood flow, the pulmonary arteries start as the pulmonary trunk or main pulmonary artery. the main pulmonary artery begins at the base of the right ventricle. it is short and wide—approximately in length and in diameter.
