Through what does blood pass after leaving the right ventricle during contraction of the heart?

After leaving the right ventricle during contraction, blood is directed into the pulmonary artery. This is a crucial part of the cardiac cycle, specifically during the phase known as systole, when the heart pumps blood.

The right ventricle's contraction forces blood into the pulmonary artery, which carries deoxygenated blood away from the heart towards the lungs. In the lungs, blood is oxygenated before returning to the heart through the pulmonary veins. This process is essential because it allows for the removal of carbon dioxide from the blood and replenishing it with oxygen.

The aorta, on the other hand, carries oxygenated blood from the left ventricle to the rest of the body. The vena cava serves as a large vein that returns deoxygenated blood to the right atrium of the heart from the body. The mitral valve, meanwhile, ensures one-way blood flow between the left atrium and the left ventricle and is not involved in the flow of blood out of the right ventricle. Hence, the pathway of blood from the right ventricle during contraction is specifically through the pulmonary artery.
