Respiratory Anatomy

2. The area of the respiratory tract where gas exchange occurs, primarily consisting of respiratory bronchioles, alveolar ducts, and alveoli.
4. prevents food from getting into the airways.
6. Transports air from the nasal cavity to the terminal bronchioles without any gas exchange.
7. A ring-shaped cartilage located below the thyroid cartilage.
11. Pleural membrane attached to the thoracic wall.
12. The exchange of oxygen and carbon dioxide between the blood and the tissues.
14. One of the paired cartilages in the larynx
15. Exchanging oxygen and carbon dioxide between the external environment and the blood.
16. Pleural membrane attached to the lungs.

1. The narrowing of the bronchi due to contraction of smooth muscles.
3. The process by which cells use oxygen to produce energy (ATP) from nutrients.
5. The widening of the bronchi caused by sympathetic activation, reducing airway resistance.
8. The only elastic cartilage of the larynx.
9. The part of the respiratory system above the larynx.
10. The largest cartilage of the larynx, commonly known as the Adam’s apple.
13. The part of the respiratory system below the larynx.
