What is the destination of the blood carried by the pulmonary arteries?

The blood carried by the pulmonary arteries is directed from the right ventricle of the heart to the lungs. This is an essential part of the pulmonary circulation process, where deoxygenated blood is transported to the lungs for oxygenation. Upon reaching the lungs, carbon dioxide is exchanged for oxygen, which is then carried back to the heart by the pulmonary veins, entering the left atrium.

This function is critical for maintaining proper gas exchange and ensuring that oxygen-rich blood is available for distribution throughout the body. Understanding this process is vital as it highlights the distinct roles of the heart's chambers and the pathways that blood takes in the circulatory system.
