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. It then flows back to your heart, which pumps the refreshed blood out through your aorta to nourish your body again.
Apr 13, 2024 · The path of blood flow through the heart and lungs is pulmonary circulation, while the blood supply to the heart itself is coronary circulation. Pulmonary Circulation: Purpose: Pulmonary circulation is responsible for oxygenating the blood. It involves the movement of deoxygenated blood from the right side of the heart to the lungs and then ...
Jul 9, 2020 · Left Atrium & Right Atrium. The atria are the top two chambers of the heart that receive incoming blood from the body. The right atrium receives deoxygenated blood through the superior and inferior vena cavas from the body and pumps it to the right ventricle through the tricuspid valve, which opens to allow the blood flow through and closes to prevent blood backing up the atrium.
Jul 16, 2024 · Oxygenated blood from the left side of the heart gets pumped out of the aorta. From there, blood flows through arteries, arterioles, and then capillaries (tiny blood vessels that transport blood, nutrients, and oxygen to cells). Deoxygenated blood from the capillaries then flows back to the heart through venules, veins, and ultimately through ...
Mar 24, 2022 · Adding oxygen to blood. 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 pulmonary artery then carries the oxygen-poor blood from your heart to the ...
Figure 2. 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.

Sep 21, 2021 · The circulatory system (cardiovascular system) pumps blood from the heart to the lungs to get oxygen. The heart then sends oxygenated blood through arteries to the rest of the body. The veins carry oxygen-poor blood back to the heart to start the circulation process over. Your circulatory system is critical to healthy organs, muscles and tissues.
