Question

n 7. There is an exchange of _____________ and _____________ gases

in the lungs.​

Answer 1

Explanation:

The lungs normally have a very large surface area for gas exchange due to the alveoli. Diseases such as emphysema lead to the destruction of the alveolar architecture, leading to the formation of large air-filled spaces known as bullae. This reduces the surface area available and slows the rate of gas exchange.During gas exchange oxygen moves from the lungs to the bloodstream. At the same time carbon dioxide passes from the blood to the lungs. This happens in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli.
