A. Ovaries.
B. Lungs.
C. Kidneys.
2. What is the trachea?
A. The tube connecting the lungs to the outside of the body.
B. The network of second-largest air sacs within each lung.
C. The outermost lining of the lungs.
3. What is the diaphragm?
A. The seal of tissue at the top of the trachea that stops food or drink from being
inhaled.
B. A sheet of muscle beneath the lungs that is essential for breathing.
C. The cup-like structure found at the base of each lung that aids the gas
exchange.
4. How do the lungs stay inflated?
A. Each lung is ribbed with cartilage to prevent collapse on exhalation.
B. The lungs are tethered to the ribcage with a network of connective tissue.
C. The lungs rely on a vacuum within the chest, maintained by the diaphragm.
5. What is the name of the rib muscles that contribute to breathing?
A. The intercostal muscles.
B. The latissimus dorsi muscles.
C. The quadriceps.
6. What are the alveoli?
A. The medical name for the vocal cords.
B. The finger-like cells that make up the outer lining of each lung.
C. The smallest air sacs of the lungs.
7. Where does the exchange of oxygen and carbon dioxide take place?
A. At the point where the trachea joins the lungs.
B. Within the alveoli.
C. Inside the right atrium of the heart.
8. How does the respiratory system contribute to speech?
A. The lungs push blood through the vocal cords.
B. Special glands attached to the trachea pump liquidised carbon dioxide into
the cells of
the vocal cords.
C. Exhaled air from the lungs vibrates the vocal cords.
9. A cough is caused by
A. Alien forces, which pull the fast-moving air right out of us
B. Irritation of the nasal passages by dust particles
C. Too many Homo sapiens in the vicinity
D. Irritation of the trachea by bacteria and dust particles
10. The respiratory system interacts with these systems of the body
A. Digestive System
B. Circulatory System
C. “A” and “B”
D. Reproductive System
11. A muscle that aids in breathing is the
A. Diaphragm
B. Triceps C. Biceps
D. Dermis
True False
12. Movement of air in and out of the lungs is called ventilation.
13. The pharynx is located behind the oral cavity and between the nasal cavity
and larynx.
14. The vocal cords are located in the pharynx.
15. The larynx connects directly to the oral cavity.
16. The trachea is flexible, but contains hyaline cartilage that helps prevent it
from collapsing.
17. The bronchial tree consists of branched airways leading from the trachea to
the microscopic air sacs in the lungs called alveoli.
18. Primary bronchi are larger in diameter than secondary bronchi, which are
larger in diameter than bronchioles
19. A young adult will typically have about 300 million alveoli.
20. Alveoli contain simple columnar epithelial cells through which gases can
easily be exchanged.
