Explanation:
Detailed explanation-1: -Tiny air sacs at the end of the bronchioles (tiny branches of air tubes in the lungs). The alveoli are where the lungs and the blood exchange oxygen and carbon dioxide during the process of breathing in and breathing out.
Detailed explanation-2: -Carbon dioxide goes from the capillaries around the alveoli into the alveoli. Then carbon dioxide goes up the bronchioles to the bronchi, and then to the trachea to be exhaled.
Detailed explanation-3: -Diffusion is the spontaneous movement of gases, without the use of any energy or effort by the body, between the alveoli and the capillaries in the lungs.
