Which vessel drains the coronary blood from the right ventricle?

The small cardiac vein is responsible for draining the coronary blood from the right ventricle. It runs along the right atrioventricular sulcus and collects blood from the right ventricle, particularly from the area supplied by the right coronary artery.

This vein plays a significant role in the coronary venous system, as it helps return deoxygenated blood from the myocardium of the right ventricle to the coronary sinus, which ultimately drains into the right atrium of the heart. Understanding the anatomy of the cardiac veins is crucial for comprehending how the heart manages its own blood supply, particularly in a clinical context.
