13 Απρ 2024 · The left side of the heart receives oxygenated blood from the lungs and pumps it to the body. This is a big task, which is why the left ventricle is the largest and strongest heart chamber. The valves between the chambers control the flow of blood and prevent it from flowing backwards.
Blood flows through your heart, lungs and body in a series of steps. After delivering oxygen and nutrients to all your organs and tissues, your blood enters your heart and flows to your lungs to gain oxygen and get rid of waste.
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.
16 Ιουλ 2024 · Blood flow through the heart involves contractions of the heart muscle to move blood from the right chambers of the heart to the lungs—where it receives oxygen—and then to the left chambers of the heart where it is pumped to the rest of the body through a network of blood vessels.
24 Μαρ 2022 · Oxygen-poor blood from the body enters your heart through two large veins called the superior and inferior vena cava. The blood enters the heart's right atrium and is pumped to your right ventricle, which in turn pumps the blood to your lungs.
The cardiovascular system is composed of two circulatory paths: pulmonary circulation, the circuit through the lungs where blood is oxygenated; and systemic circulation, the circuit through the rest of the body to provide oxygenated blood.
The heart functions as a double ventricle. Blood moves from the body into the right atrium and then into the right ventricle, where it is pumped into the lungs. Blood becomes oxygenated in the lungs, moves into the left atrium and into the left ventricle, where it is pumped into the body again.
