Answer:

1. Trachea.

Explanation:

The trachea is a tube-like structure within the neck and upper chest. It transports air to and from the lungs when a person breathes. When a person inhales, air travels through the nose or mouth, down the trachea, and into the lungs.

2. pharynx .

The pharynx, commonly called the throat, is a

passageway that extends from the base of the skull to the level of the sixth cervical vertebra. It serves both the respiratory and digestive systems by receiving air from the nasal cavity and air, food, and water from the oral cavity.

3. Diaphragm.

Diaphragm, dome-shaped, muscular and membranous structure that separates the thoracic (chest) and abdominal cavities in mammals; it is the principal muscle of respiration.

4. Alveoli.

The alveoli are where the lungs and the blood exchange oxygen and carbon dioxide during the process of breathing in and breathing out. Oxygen breathed in from the air passes through the alveoli and into the blood and travels to the tissues throughout the body.
