REVIEW
Respiratory & Excretory
Systems
1. Which is the correct sequence for the path
of oxygen through the respiratory system?
•
•
•
•
•
•
•
•
Nasal cavity
Pharynx
Larynx
Trachea
Bronchi
Bronchial Tubes
Bronchioles
Alveoli
2. The tubes that branch from the trachea are the
• bronchi
3. The dome shaped muscle below the chest cavity is called the
• diaphragm
4. During swallowing, the air passage of the pharynx is covered by the
• epiglottis
5. Alveoli in the lungs are connected to the bronchial tubes by a network of
tiny tubes called
• Bronchioles
6. Explain what happens to gases during gas exchange in the alveoli.
• Oxygen in alveoli diffuses into capillaries (blood).
• Carbon dioxide in capillaries (blood) diffuses into alveoli.
7. Where are the vocal cords located in the body?
• larynx
8.What prevents the trachea from collapsing?
• Rings of cartilage
9. Where does the actual exchange of gases occur?
• Alveoli
10. During gas exchange where does the oxygen and carbon
dioxide go?
• Oxygen diffuses into capillaries while carbon dioxide
diffuses out of capillaries into the alveoli.
11. The ______ is a long straight tube that carries air from
the back of the throat to the lungs.
• Trachea
12. What structures trap foreign particles and bacteria in the
nose and trachea?
a) pharynx
b) epiglottis
c) cilia
d) trachea
c
13. The order of air movement with in the lungs is best described as
a)
bronchioles to bronchi to alveoli
b) bronchi to bronchioles to alveoli
c)
trachea to bronchi to alveoli
d) bronchi to alveoli to bronchioles
c
14. Where are the vocal cords located in the body?
• Larynx
15. During swallowing, the air passage of the pharynx
is covered by the
• Epiglottis
16. The FIRST branches off the trachea are called
• bronchi
17. What prevents the trachea from collapsing?
• rings of cartilage
18. Alveoli in the lungs are connected to the bronchi by a
network of tiny tubes called
a) arterioles
b) venules
c) capillaries
d) bronchioles
d
19. Inside the alveoli, carbon dioxide and oxygen
a) are transported along microscopic tubules
b) are exchanged between air and blood
c) are produced inside cells
d) are exchanged for other gases
b
20. Humans breathe more rapidly during exercise than before
it because during exercise the blood contains
1. an increased level of oxygen
2. a decreased number of red blood cells
3. an increased level of carbon dioxide
4. a decreased amount of hemoglobin
3
21. What happens to each of the
following during inhalation?
a. Diaphragm
• Contracts (pulls down)
22. What happens to each of the
following during exhalation?
a. Diaphragm
• Relaxes (moves up)
23. Identify the
structures

A – nasal cavity

circulatory
32.
It came from the lungs.
33.
Oxygen moves from the alveoli (respiratory
system) into the capillaries (circulatory) while
carbon dioxide moves from the capillaries into
the alveoli.
34.Identify A, B, and D.
lung
liver
kidney
35. Which organ
produces urea?
• B. Liver
36. What is the function of
D?
•
Filter wastes from blood.
•
Regulate water
concentration of blood.
•
Produce urine
37. What does organ A
excrete?
• Carbon dioxide, water vapor
38. Which organ detoxifies the
blood?
• kidneys
39. What are metabolic
wastes? Examples?
• Wastes from your cells
• CO2, H2O, salts, urea
40. Identify structures A, B, C, and D.
Kidney
Ureter
Urinary
bladder
Urethra
41. Which structure produces
urine?
• A - kidneys
42. What is the path of urine?
• Kidneys  ureters  urinary
bladder  urethra
43. What stores urine?
• Urinary bladder
44. What is the function of D?
• To allow urine to pass out
of the body
45. Which human excretory structure
aids in the maintenance of normal body
temperature?
• Skin
46. Why is the skin also an excretory
organ?
• It excretes water, salt, and urea in
the form of perspiration (sweat).
