Heart

So today, we are going to learn about Heart

So, our heart is made up of four chambers - Right atrium, Left atrium, Right ventricle and Left ventricle

It starts from the upper right atrium, when the deoxygenated blood enters to our heart. Then the blood goes through the tricuspid valve to right ventricle which pumps the blood to the left direction through the pulmonary valve and then, through the pulmonary artery, it goes to the lungs and that's the place where it mixes with the oxygen. Then the oxygenated blood travels back through the pulmonary vein into the left atrium and then, through the mitral valve, it comes to the left ventricle and then pumps out to the rest of the body. This is how the heart pumps blood.
