Pulmonary circulation carries oxygen depleted blood from the heart to the ____.

The pulmonary circulation is specifically designed to transport oxygen-depleted blood from the right side of the heart to the lungs. In the lungs, carbon dioxide is exchanged for oxygen, thereby reoxygenating the blood. This process is crucial for maintaining proper oxygen levels in the body and supporting cellular respiration. The right ventricle pumps the deoxygenated blood into the pulmonary arteries, which then branch into the lungs. Once the blood is oxygenated in the lungs, it returns to the left side of the heart through the pulmonary veins, ready to be pumped out to the rest of the body. Understanding this process highlights the unique role of the lungs in the circulatory system and emphasizes the importance of pulmonary circulation in overall cardiovascular function.
