Anatomy CH. 13

4. Consists of the trachea, bronchi, bronchioles, and lungs; involved in gas exchange and air transport.
6. The thin fluid-filled space between the two layers of the pleura (membranes surrounding the lungs), allowing smooth lung movement during breathing.
9. A muscular tube that connects the nose and mouth to the larynx and esophagus; it serves as a pathway for both air and food.
10. Also called the windpipe, this tube carries air from the larynx down into the bronchi and lungs.
14. The amount of air remaining in the lungs after a maximum exhalation; prevents lung collapse.
15. The amount of air inhaled or exhaled during a normal breath.
16. Smaller branches of the bronchi that further divide and lead to the alveoli; they help control the flow of air.

1. A condition in which fluid accumulates in the alveoli of the lungs, making it difficult to breathe and impairing gas exchange.
2. Includes the nose, nasal cavity, sinuses, pharynx, and larynx; responsible for filtering, warming, and humidifying incoming air.
3. Bands of muscle located in the larynx that vibrate to produce sound when air passes through them.
5. Also known as the voice box, it is located below the pharynx and contains the vocal cords; it directs air into the trachea and helps produce sound.
7. A pair of spongy organs where gas exchange occurs; oxygen is absorbed into the bloodstream and carbon dioxide is released.
8. A device used to measure lung volumes and capacities, especially vital capacity and tidal volume.
11. The two main branches of the trachea that lead into the left and right lungs, carrying air deeper into the lungs.
12. The maximum amount of air a person can exhale after a maximum inhalation; indicates lung health.
13. Tiny air sacs at the end of bronchioles where gas exchange takes place between the lungs and the blood.
