Where does blood flow after leaving the right atrium?

After blood leaves the right atrium, it flows into the right ventricle. This movement is a crucial part of the circulatory process. The right atrium receives deoxygenated blood from the body via the superior and inferior vena cavae. Once filled, the right atrium contracts and allows the blood to flow through the tricuspid valve into the right ventricle.

The right ventricle then plays its role by contracting to send the deoxygenated blood into the pulmonary arteries, where it travels to the lungs for oxygenation. Each component of this sequence is essential for maintaining efficient blood circulation and ensuring that oxygen-poor blood is adequately processed before returning to the heart for replenishment with oxygen. Understanding the pathway of blood flow is fundamental in health science, as it illustrates the structure and function of the heart and vascular system.
