Which chamber of the heart does the right atrium lead into?

The right atrium is one of the four chambers of the heart and plays a crucial role in the circulatory system. It receives deoxygenated blood from the body through the superior and inferior vena cavae. From the right atrium, blood is directed into the right ventricle.

The right ventricle then pumps this deoxygenated blood to the lungs via the pulmonary arteries, where it gets oxygenated. This flow of blood is a vital part of the pulmonary circulation process. Understanding the sequence of blood flow through the chambers of the heart is essential for grasping how the heart functions and how it supports the body's overall circulatory system.
