Answer:

True

Explanation:

The nostrils are two cavities that connect the respiratory system with the outside through the nose. In them the air is heated, moistened and cleaned of dust that is retained in the entrance hairs.

The larynx is a tube that contains the vocal cords, which are the ones that produce the sound when vibrated by the passage of air.

The pharynx is a cavity that communicates the mouth, the nose, the entrance of the esophagus and the larynx.

The trachea is a rigid tube that conducts air to the bronchi.

The bronchial tubes are don ducts with ramifications, called bronchioles, that introduce air into the lungs.

The lungs are two spongy organs formed by millions of sacs called alveoli.

The alveoli are small chambers with very thin walls in which gas exchange occurs, oxygen passes into the blood and carbon dioxide is expelled outside.

The diaphragm is a flat muscle that is involved in respiratory movements.
