Yes, lungs carry blood. The lungs play a vital role in the circulatory system by oxygenating blood.
How Lungs Carry Blood and Oxygenate It
The primary function of the lungs is to facilitate gas exchange, where carbon dioxide is removed from the blood and replaced with oxygen. This process involves blood being transported to and through the lungs.
- Deoxygenated Blood Arrives: Blood low in oxygen, and high in carbon dioxide, enters the lungs via the pulmonary arteries.
- Gas Exchange: Within the lungs, specifically in the alveoli, oxygen from the inhaled air diffuses into the blood, while carbon dioxide diffuses from the blood into the alveoli to be exhaled.
- Oxygenated Blood Returns: According to information available on how lungs work, the oxygen-rich blood returns to your heart through the pulmonary veins. This oxygenated blood is then pumped from the heart to the rest of the body.
Therefore, the lungs act as a crucial intermediary in the circulatory system, carrying blood to enable this vital gas exchange.
