On the left side. Oxygen-rich blood travels from your lungs to your left atrium through large veins called pulmonary veins. These veins directly empty the blood into your left atrium. Your mitral valve opens to send blood from your left atrium to your left ventricle.
The right ventricle pumps oxygen-depleted blood into the pulmonary trunk and right and left pulmonary arteries, which carry it to the right and left lungs for gas exchange. Oxygen-rich blood is transported by pulmonary veins to the left atrium. The left ventricle pumps this blood into the aorta.

Apr 13, 2024 · The short answer is that deoxygenated blood from the body enters the right atrium of the heart and the right ventricle pumps it to the lungs. The oxygenated blood returns to the heart, entering the left atrium, while the left ventricle pumps it to the body.
Oct 30, 2023 · Oxygenated blood from the lungs is circulated back to the heart through the pulmonary veins that drain into the left atrium. Once blood is pumped from the left atrium through the mitral valve into the left ventricle, this oxygenated blood will then be pumped from the left ventricle through the aortic valve to the rest of the body’s organs and ...

Nov 3, 2024 · 1. Blood Enters the Right Atrium. The journey of blood flow through the heart begins as deoxygenated blood, rich in carbon dioxide, enters the right atrium. This blood arrives from the upper part of the body via the superior vena cava and from the lower part of the body via the inferior vena cava. 2.
Oct 30, 2023 · Oxygen-rich blood is then returned to the left side of the heart, specifically the left atrium, via the pulmonary veins. The cycle then repeats itself. In contrast to systemic circulation, the vessels within the pulmonary circulation are fairly short, given the close relation of the heart and lungs.
Blood from the lungs, which is now oxygen-rich, flows through the pulmonary veins into the left atrium. When the left ventricle relaxes, the blood in the left atrium pours through the mitral valve into the left ventricle.
