Heart

The heart is a muscular fist-sized organ. It's the primary organ of the circulatory system that pumps blood through the network of arteries and veins.

Aorta

The aorta is the main and largest artery in the human body whose only and important function is to carry oxygenated blood from the heart to the rest of the body.

Superior Vena Cava

The vena cava is a large, significant vein responsible for returning deoxygenated blood collected from structures located above the diaphragm back to the heart.

Pulmonary Vein

The Pulmonary Vein is a vein that collects oxygen-rich blood from the lungs and transfers it to the heart.

Pulmonary Artery

A pulmonary artery is an artery in the pulmonary circulation that carries deoxygenated blood from the right side of the heart to the lungs.
