Which blood vessel brings deoxygenated blood from the heart to the lungs?

The pulmonary artery is the blood vessel responsible for transporting deoxygenated blood from the heart to the lungs. Specifically, it carries this blood from the right ventricle of the heart to the lungs for oxygenation. In the lungs, carbon dioxide is exchanged for oxygen, leading to the enrichment of the blood with oxygen before it returns to the heart through the pulmonary veins.

Understanding the role of the pulmonary artery is essential in the context of the circulatory system. It is unique because, unlike most arteries which carry oxygenated blood, the pulmonary artery conveys deoxygenated blood, making it a vital component in the pulmonary circulation process. This differentiation in function is crucial for maintaining proper oxygen levels in the body and highlights the specific pathways that blood takes depending on its oxygenation status.
