Major Blood Vessels Returning to the Heart: A Comprehensive Guide

The major blood vessels that return blood to the heart are:

1. Superior Vena Cava (SVC):

- Drains blood from the upper body, including the head, neck, arms, and chest.

2. Inferior Vena Cava (IVC):

- Drains blood from the lower body, including the abdomen, pelvis, and legs.

3. Coronary Sinus:

- Drains blood from the heart muscle itself.

These three vessels deliver deoxygenated blood to the right atrium of the heart, which then pumps the blood to the lungs for oxygenation.
