Across
- 3. Carries air to the sac-like structures in the lungs.
- 5. ____________ capillaries encircle each individual alveoli allowing for the exchange of oxygen and carbon dioxide.
- 9. The process of letting air out of the lungs during the breathing cycle.
- 10. ___________ cell anemia is a disease that causes blood cells to have a sickle shape. Causes a decrease in oxygen carrying capacity.
- 13. The system that uses lungs, nose, and mouth to let you breathe.
- 14. The process of taking air into the lungs during the breathing cycle.
- 15. A fluid lubricant secreted by surfaces of the pleura.
- 17. Peripheral chemoreceptor bodies that are located in the carotid sinus.
- 19. Most oxygen in the blood is transported/bound to this in the red blood cells.
- 21. Thin-walled inflatable sacs that aid in gas exchange.
- 23. Carbon __________ is a waste gas that the body produces. Exhaled out of body through lungs.

Down
- 1. Respiratory group that is active in normal quiet breathing.
- 2. Increased pulmonary ventilation in excess of metabolic requirements.
- 4. Underventilation in relation to metabolic requirements.
- 6. Double-walled, closed sac that separates each lung from the thoracic wall.
- 7. The organ that acts as a passageway for air to enter the larynx. Also allows food and liquid to enter esophagus.
- 8. The main muscle we use during quiet(resting) inspiration.
- 11. Peripheral chemoreceptor bodies that are located in the aortic arch.
- 12. Allows the passage of inspired and expired air into and out of the lung.
- 16. Carbon __________ is a colorless odorless gas that is the leading cause of death by poison worldwide.
- 18. Law that states that at any constant temperature, the pressure exerted by a gas varies inversely with the volume of a gas.
- 20. Colorless, odorless, tasteless gas that is essential to all living organisms.
- 22. The hollow muscular organ that allows the passage of air to go to the lungs. Also known as the voice box.
