Air (and not food) pass in which of the following areas: A. Esophagus Correct Answer B. Nasopharynx You Answered C. Oropharynx D. Both A. and C.

Question 3

3 / 3 pts

In the respiratory system, gas exchange occurs in the: A. Bronchi B. Respiratory bronchioles C. Terminal bronchioles D. Pulmonary alveoli Correct! E. B &D Question 4

Label the following five items from the diagram:

Question 5

5 / 5 pts

Note: Essay answers must clearly be in your own words. Explain what happens to the soft palate during swallowing. Why? Your Answer: Larynx rises, the epiglottis closes the trachea. soft palate moves to prevent food going into the nasal path. to avoid choking while eating The upward movement of the soft palate prevents food or liquid from entering the nasal passages during swallowing. Question 6

5 / 5 pts

Note: Essay answers must clearly be in your own words. Explain at least two differences between Type I and Type II alveolar cells. Your Answer: 95% of alveolar epithelium cells makes up type I. They have simple squamous epithelium that are thin type II is 5 % of alveolar cells, divides to replace damaged type I a. Type I form the very thin simple squamous epithelium of the alveoli in junction with capillaries. Make up roughly 95% of alveolar epithelial cells. b. Type II produce and secrete pulmonary surfactant which is needed throughout the alveolar surface to keep the alveoli open. In addition, Type II cells can divide to replace damaged Type I cells. Make up roughly 5% of alveolar epithelial cells. Question 7

2 / 2 pts

True/False: Positive pressure is used to move air into the lungs. True Correct!

False (Negative pressure) Question 8

2 / 2 pts

True/False: During inhalation the diaphragm contracts to pull the lungs open. Correct! True False Question 9

2 / 2 pts

True/False: During inhalation the rib cage lifts in an upward motion to open and expand the lungs. Correct! True False Question 10

2 / 2 pts

True/False: As the thoracic cavity expands and lung volume increases, the density of the gases filling the lungs decreases. Correct! True

2 / 2 pts

Typical respiratory epithelium contains all of the following, except which one? cilia Correct! layers tall, narrow cells mucus producing cells goblet cells Question 14

2 / 2 pts

Which one of the following is not true of the pleurae? The pleurae are membranes that cover surfaces Parietal pleurae cover the surfaces surrounding the lungs Correct! Visceral pleurae cover the diaphragm A healthy pleural cavity is nearly empty of air or fluid

Question 15

2 / 2 pts

Which one of the following is not true of the respiratory physiology? Correct! Tidal volume is the maximum amount of air able to be inhaled beyond normal inhalation Tidal volume is the amount of air inhaled and exhaled in one cycle of quiet breathing Inspiratory reserve volume is the maximum amount of air able to be inhaled beyond normal inhalation Expiratory reserve volume is the maximum amount of air able to be exhaled beyond normal exhalation Question 16

2 / 2 pts

Which one of the following is true of the respiratory physiology calculations? ( You may find it helpful to draw the respiratory physiology diagram on a piece of scratch paper. ) Vital Capacity (VC) = ERV+TV Correct! Total Lung Capacity (TLC) = VC +RV Inspiratory Capacity (IC) = TV+RV Functional Residual Capacity (FRC) = IRV + TV

Correct! False stratified squamous epithelium is found in the vestibule Question 20

0 / 2 pts

True/False: Because of diffusion, oxygen naturally moves out of the blood and into the lungs. You Answered True Correct Answer False Question 21

2 / 2 pts

True/False: The bronchioles are surrounded by capillaries for gas exchange. True Correct! False Question 22

10 / 10 pts

Matching:

-Smoking is often the cause of this disease. A. Emphysema -With this disease, mucus clogs the respiratory tract. B. Pleurisy -This condition results in fluid-filled alveoli. C. Pulmonary edema -This is inflammation of the pleurae. D. Cystic Fibrosis Correct! Smoking is often the cause of this disease. Correct! With this disease, mucus clogs the respiratory tract. Correct! This condition results in fluid-filled alveoli. Correct! This is inflammation of the pleurae. Question 23

4 / 4 pts

The pressure of three gases equals 1 atmosphere. What is the partial pressure of oxygen (in mmHG) if nitrogen is 300 mmHg and carbon dioxide is 350 mmHg? To receive full credit you must show your work. Your Answer: 1 atm= 760 mm Hg A. Emphysema D. Cystic Fibrosis C. Pulmonary edema B. Pleurisy

3 / 3 pts

In gas exchange (external respiration): Carbon dioxide diffuses from alveoli into capillaries, oxygen diffuses from capillaries into alveoli Oxygen and carbon dioxide is carried from alveoli into the bronchioles Correct! Oxygen diffuses from alveoli into capillaries, carbon dioxide diffuses from capillaries into alveoli Oxygen is chemically transformed into carbon dioxide within the alveoli Question 28

3 / 3 pts

The purpose of these cells are the primary immune defense of the alveoli: Type I alveolar cells

Type II alveolar cells Surfactant Correct! Alveolar macrophages Question 29

10 / 10 pts

Answer the following essay question (10 points):

  1. Muscular dystrophy is a neuromuscular disease which restricts the lungs from fully expanding due to muscular weakness. If a person is diagnosed with muscular dystrophy:
  1. Which of the following statements regarding pulmonary function would be true?
  2. Explain your answer. A. Inspiratory capacity would be abnormally low B. Vital capacity would abnormally high C. Total lung capacity would remain the same Your Answer: A Inspiratory capicity would be abnormally low. Thie disease can restrict the lungs from full expansion due to muscular weakness. The patient would not have the ability to breath the normal amount of air needed into their lungs at all times. A. Inspiratory capacity would be abnormally low Vital capacity would decrease because there is a decreased ability to bring in as much air compared to normal values because of muscular weakness. Inspiratory Capacity (IC) = TV+IRV (or) VC-ERV Decreased VC, decreased IC Quiz Score: 95 out of 100
