key term - Ventricle

Definition

In the context of heart anatomy, a ventricle is one of the two lower chambers of the heart that receive blood from the atria above them and pump it out to the body (left ventricle) or to the lungs (right ventricle). These muscular chambers are crucial for the circulatory system’s function, propelling oxygenated and deoxygenated blood to their respective destinations.
