Name_____________________________
Circle the right answer or answers:
1. Which of these statements are true:
A. Respiration is the exchange of oxygen and carbon dioxide
between the atmosphere and the body cells.
b. Respiration occurs at the level of the cells and in the alveoli.
c. Diffusion is the movement of gas from an area of high
concentration to an area of lower concentration.
d. Respiration is when a resper sweats or perspirates.
e. Diffusion is when you fuse two dies.
2. Which of these statements are true?
a. The key function of lung is to bring air and blood into intimate
contact in the alveolar air sacs so that oxygen can enter the blood,
and carbon dioxide can leave.
b. The Alveoli are the smallest part of the lung, the balloon like air
sacs.
c. Aleve is a group of alveoli.
d. All the body cells metabolically consume oxygen, and discharge
carbon dioxide. To cover this need, respiration takes place in the
lungs and we call it ventilation or breathing.
3. Which of these statements are true:
a. Gas exchange occurs in the lungs between the alveoli and a
capillary network within the alveolar wall.
b. Capillaries are microscopic blood vessels that exchange material
between the blood and body tissues.
c. Gas exchange is where you buy and sell gas.
d. Alveolus is smallest anatomic part of the lung, where gas
exchange takes.
4. Which of these statements are true:
a. The alveolar wall is the physical structure which separates the
alveolus from the interstitium.
b. The alveolar interstitium is the loose tissue separating the alveoli
and the alveolus from the pulmonary capillary.
c. Alvin is a not the name of a famous chipmunk.
d. Ventilation involves the inhalation of atmospheric air into the lungs via
the nose and mouth through branching passageways, and the exhalation
of carbon dioxide
5. Which of these statements is/are true:
a. The pulmonary capillary wall is the wall separating the oxygen
poor, carbon dioxide rich pulmonary capillary blood from the
interstitium.
b. The pulmonary capillary is the smallest blood vessel in the lung
where the exchange of oxygen and carbon dioxide takes place.
c. The lung is made of millions of alveoli
c. Oxygen diffuses across the capillary wall and Interstitium into the
red blood cell.
d. Carbon dioxide diffuses across the capillary wall and Interstitium
into the alveoli.
6. Which of these statements are true:
a. Oxygen concentration is the percentage of oxygen in the air
presented to the alveolus.
b. Partial pressure of oxygen is the atmospheric pressure on the
oxygen delivered to the alveolus
c. Ventilation is the mechanical exchange of air between the lungs
and the atmosphere.
d. Alveolar ventilation is the exchange of air between the alveoli and
the atmosphere.
7. Which of these statements is/are true
a. Respiration is the exchange of oxygen and carbon dioxide
between the atmosphere and the body cells. This occurs inside
cells and in the alveoli.
b. Alveolar respiration is the exchange of oxygen and carbon dioxide
between the atmosphere and the alveoli.
c. Alvin inspiration is the exchange of gases in the vein.
8. Which of these statements is/are true
Alveolar respiration or the exchange of oxygen and carbon dioxide
occurs in the alveolus due to?
a. A concentration gradient or difference.
b. A pressure gradient or difference.
c. Alveolar respiratory gradient
9. Which of these statements is/are true
a. Oxygen moves or “diffuses” from the oxygen rich air in the alveoli
to the oxygen poor blood in the alveolar capillary.
b. It follows a “concentration gradient” which means the oxygen
moves from a high oxygen area to a low oxygen area.
c. When we administer high flow oxygen by mask, we increase the
concentration of oxygen in the alveolus and this makes more oxygen
diffuse or move into the capillary and therefore the blood.
10. Which of these statements is/are true
a. Partial pressure of oxygen-the atmospheric pressure on the
oxygen delivered to the alveolus.
b. The atmospheric pressure at sea level is one atmosphere or
760 mm of mercury.
c. The partial pressure of a gas is calculated by multiplying it’s
concentration by the atmospheric pressure.
d. The oxygen concentration in air is 21%, so 760 x 21% gives a
partial pressure of oxygen of 159.6.
11. Which of these statements is/are true:
a. The pressure of the atmosphere on oxygen, also called the “partial
pressure” of oxygen is higher in the alveolus then the partial
pressure of oxygen in the capillary blood.
b. This pressure difference creates a “pressure gradient” which
makes oxygen “diffuse” or move from the alveolus air into the blood
in the capillary surrounding the alveolus.
c. When we administer CPAP, or “continuous positive air
pressure” we are adding pressure to the atmospheric pressure
on the oxygen.
d. This increases the “partial pressure” of oxygen in the alveolus.
e. This increase in the pressure difference increases the “pressure
gradient” and makes more oxygen “diffuse” or move into the
capillary blood around the alveolus.
12. CPAP takes advantage of the physical forces which improve
alveolar capillary blood oxygenation;
a. Concentration
b. Pressure
c. Air temperature
d. Wind chill factor
e. A&B
f. C&D
g. A&C
h. B&D
