Answer 2

Answer:

The pathway of air beginning with the intake of air and ending at the alveoli in this following ways :-

- Air enters through the nose (and sometimes the mouth), moves through the nasal cavity, the pharynx, the larynx, enters the trachea, moves through the bronchi and bronchioles till the alveoli.

- Air ends its pathway in the alveoli (sing. alveolus) which are tiny sacs with very fine singe-celled walls.

- These alveoli are surrounded by capillaries that connect the pulmonary arteries and veins and that enable transfer of oxygen and carbon dioxide.
