Module 4 Quiz

1Surfactant facilitates alveolar ventilation by

decreasing the surface tension between water molecules on the lining of the alveoli.

increasing the surface tension between fluid and the alveoli.

attracting water to the alveolar surface.

decreasing thoracic compliance.

2Which of the following statements concerning the lungs and the pleura is true?

The pleural fluid assists in gas exchange.

The space between the visceral and parietal pleurae is called the mediastinum.

Each lung is suspended in a separate pleural cavity.

Parietal pleura covers the surface of each lung.

3Which of the following statements concerning the larynx is correct?

Unlike other portions of the larynx, the epiglottis consists of some bony tissue.

The larynx contains four unpaired cartilages.

The inferior laryngeal cartilage is the thyroid cartilage.

When the glottis closes, air is prevented from leaving the lungs.

4If a person develops high blood pressure, one of the compensatory mechanisms that comes into play is the fluid shift mechanism. This mechanism causes

increased filtration in the kidney, thereby increasing urine output.

water to shift from the capillaries into the interstitial spaces.

water to shift from inside cells into the extracellular fluid.

water to shift from the interstitial space into the capillaries.

5From largest to smallest, the correct sequence for the following passageways is

alveoli, bronchioles, terminal bronchioles, respiratory bronchioles, bronchi.

bronchioles, terminal bronchioles, respiratory bronchioles, bronchi, alveoli

bronchi, bronchioles, terminal bronchioles, respiratory bronchioles, alveoli.

bronchi, bronchioles, respiratory bronchioles, terminal bronchioles, alveoli.

See the process below.

6Match the process for #1 in the drop down.

Oxygen diffuses out of the arterial ends of tissue capillaries, and CO2 diffuses out of the tissue because of differences in partial pressures

7Match the process for #2 in the drop down.

As a result of diffusion at the venous ends of pulmonary capillaries, the PO2 in the blood is equal to the PO2 in the alveoli, and the PCO2 in the blood is equal to the PCO2 in the alveoli

8Match the process for #3 in the drop down.

The PO2 of blood in the pulmonary veins is less than in the pulmonary capillaries because of mixing with deoxygenated blood from veins draining the bronchi and bronchioles

Results for question 9.

9Match the process for #4 in the drop down.

Oxygen diffuses out of the arterial ends of tissue capillaries, and CO2 diffuses out of the tissue because of differences in partial pressures

10Match the process for #5 in the drop down.

As a result of diffusion at the venous ends of tissue capillaries, the PO2 in the blood is equal to the PO2 in the tissue, and PCO2 in the blood is equal to the PCO2 in the tissue

11Considering the distribution of sympathetic and parasympathetic fibers in the peripheral nervous system, damage to which of the following nerves would have the greatest impact on blood vessel walls?

Pelvic nerves

Cranial nerves

Thoracic nerves

Both “Pelvic nerves” and “Cranial nerves” are correct.

See the image below.

12Match A in the drop down.

Veins

13Match B in the drop down.

Arterioles

14Match C in the drop down.

Venules

 

15

Match D in the drop down.

Arteries

16Match E in the drop down.

Capillaries

17Match F in the drop down.

Venae cavae

18Match G in the drop down.

Aorta

19Indicate the statement that describes respiratory function in a highly trained athlete at maximal exercise.

Increased tidal volume; unchanged minute ventilation; unchanged alveolar ventilation

Increased minute ventilation; increased alveolar ventilation; unchanged tidal volume

Unchanged minute ventilation; increased respiratory rate; decreased vital capacity

Increased tidal volume; increased minute ventilation; increased alveolar ventilation

20Art, 75 years old, has advanced arteriosclerosis and is suffering from a number of manifestations associated with arteriosclerosis. Over the past several years he has developed hypertension and he is beginning to show signs of renal failure. Which of the following are consistent with his condition? (check all that apply)

Increased resistance to blood flow

Increased aldosterone secretion from the adrenal cortex

Increased angiotensinogen formation

Increased renin secretion from the kidneys
