Right Side. Blood flows from your right atrium into your right ventricle through the open tricuspid valve. When the ventricles are full, the tricuspid valve shuts. This prevents blood from flowing backward into the atria while the ventricles contract.eft Side. Blood flows from your left atrium into your left ventricle through the open mitral valve. When the ventricles are full, the mitral valve shuts. This prevents blood from flowing backward into the atria while the ventricles contract.
The blood travels into the right atrium and, during the contraction of the atrium, flows through the tricuspid valve into the right ventricle. The blood is pushed through the pulmonary valve into the pulmonary artery and lungs when the right ventricle contracts. Here, it picks up oxygen. The oxygenated blood is then carried back to the heart (by the pulmonary veins), into the left atrium, through the mitral valve, and into the left ventricle. Contraction of the left ventricle forces the blood through the aortic valve, through the aorta, and out to the body.
