Question

within the lungs, the exchange of oxygen and carbon dioxide occurs between the ____ and the capillaries. diaphragm trachea alveoli bronchi

Explanation:

The alveoli are tiny air sacs in the lungs. They have thin walls and are surrounded by capillaries. This structure allows for efficient gas exchange. Oxygen from the alveoli diffuses into the capillaries, and carbon dioxide from the capillaries diffuses into the alveoli. The diaphragm is a muscle for breathing, the trachea is the windpipe, and bronchi are airways. Only alveoli are directly involved in gas exchange with capillaries.
