gas transport

Gas transport involves the movement of gases, such as oxygen and carbon dioxide, between the lungs and the bloodstream. When you breathe in, oxygen enters your lungs and diffuses through thin membranes into your blood. Simultaneously, carbon dioxide, a waste product from your body, moves from the blood into the lungs to be exhaled. This exchange relies on concentration differences and the thinness of lung membranes, allowing gases to pass easily. The circulatory system then carries these gases to and from tissues, ensuring your body receives oxygen for energy and removes carbon dioxide efficiently.
