Blood is pumped by the right atrium through the mitral valve into the right ventricle
|
|
|
Blood is pumped by the right atrium into the right ventricle to the pulmonary trunk toward the lungs
|
|
|
Blood is pumped by the left ventricle through the mitral valve into the aorta
|
|
|
Blood flows from the pulmonary capillaries to the pulmonary arteries to the left atrium

Detailed explanation-1: -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 lungs. Your lungs add oxygen to your blood.
Detailed explanation-2: -The right ventricle pumps the blood from the right atrium into the lungs to pick up oxygen and remove carbon dioxide. The left atrium receives blood from the lungs. This blood is rich in oxygen. The left ventricle pumps the blood from the left atrium out to the body, supplying all organs with oxygen-rich blood.
Detailed explanation-3: -Blood Flow: Step by Step The blood first enters the right atrium. The blood then flows through the tricuspid valve into the right ventricle. When the heart beats, the ventricle pushes blood through the pulmonic valve into the pulmonary artery. The pulmonary artery carries blood to the lungs where it “picks up” oxygen.
Detailed explanation-4: -Blood comes into the right atrium from the body, moves into the right ventricle and is pushed into the pulmonary arteries in the lungs. After picking up oxygen, the blood travels back to the heart through the pulmonary veins into the left atrium, to the left ventricle and out to the body’s tissues through the aorta.
