The lungs are responsible for exchanging oxygen and carbon dioxide between the air and blood. When oxygen levels in the blood are low, the blood vessels in the lungs constrict, which redirects blood flow to parts of the lung with higher oxygen levels. Conversely, when oxygen levels are high, the blood vessels in the lungs dilate, allowing for greater blood flow to areas of low oxygen levels. This helps to ensure that oxygen delivery to the body's tissues is optimized.
