gas exchange occurs at the respiratory membrane between the
larynx and pharynx.
alveoli and blood.
trachea and bronchi.
bronchiole and alveoli.

Explanation:

Gas exchange in the respiratory system takes place at the respiratory membrane where oxygen diffuses from the alveoli into the blood and carbon - dioxide diffuses from the blood into the alveoli. The larynx and pharynx are part of the upper respiratory tract and not the site of gas exchange. The trachea and bronchi are air - conducting pathways. The bronchiole is also part of the air - conducting system until it reaches the alveoli, but gas exchange occurs specifically between the alveoli and the blood.

Answer:

alveoli and blood.
