The vena cavae collect blood from the systemic circulation. They deliver this deoxygenated blood to the right atrium.
The main vein in the body is the Vena Cavae vein. The inferior vena cavae vein carries blood from the legs and stomach to the heart. The superior vena cavae carries blood from the arms and head to the right atrium of the heart.

The junction of the Superior and Inferior Vena Cavae. The Superior Vena Cava brings blood from the upper body, and the Inferior Vena Cava brings blood from the lower body. They meet at a junction, and enter the heart.
After deoxygenated blood flows from the inferior and superior vena cavae into the right atrium, it fills the chamber and triggers the right atrium to contract. This contraction pushes the blood through the tricuspid valve into the right ventricle. Once the right ventricle is filled, it contracts, sending the blood into the pulmonary arteries via the pulmonary valve, where it travels to the lungs for oxygenation.
