The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle. The right ventricle then pumps the blood to the lungs, where it is oxygenated. The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle. The left ventricle then pumps the oxygen-rich blood to the rest of the body.
The heart is also made up of four valves that help keep the blood flowing in the right direction. The tricuspid valve is located between the right atrium and right ventricle, and the mitral valve is located between the left atrium and left ventricle. The pulmonary valve is located between the right ventricle and the lungs, and the aortic valve is located between the left ventricle and the aorta.
The heart is an amazing organ that is essential for life. Coloring pages can help children learn more about the anatomy of the heart and how it works.
