Question 1

4 / 4 pts

How many lobes does the left human lung have? Your Answer: two lobes: superior ans inferior Two Lobes

Question 2

0 / 3 pts

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.

Label B- ___________ Label D- __________ Label E- __________ Label F- __________ Label G- __________ Your Answer: b. oral cavity d. epiglottis e. glottis f. trachea g. esophagus Label B- Oral Cavity Label D- Epiglottis Label E- Glottis Label F- Trachea Label G- Esophagus

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 Question 11

2 / 2 pts

True/False: As the rib cage expands during inhalation, air will naturally flow into the lungs. Correct! True (air will naturally flow into the lungs because of the negative pressure inside the lungs) False Question 12

2 / 2 pts

Boyle's law states that gas volume is: A. Directly proportional to temperature B. Inversely proportional to temperature C. Directly proportional to pressure Correct! D. Inversely proportional to pressure E. Both A and B Question 13

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 17

2 / 2 pts

True/False: The gas-exchange region in the lungs must be dry, thin and large. True Correct! False requires moisture Question 18

2 / 2 pts

True/False: The vestibule is the most external portion of the nasal cavity. Correct! True False Question 19

2 / 2 pts

True/False: The vestibule is lined with typical respiratory epithelium. True

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:

300 mm Hg+ 350 mm Hg= 650 mm Hg 760 mm Hg- 650 mm Hg= 110 mm Hg Answer 110 mm Hg 110 mmHG 1atm= 760 mmHg 300 mmHg + 350 mmHG + X = 760 mmHg OR: 760 - 300-350= 110 mmHG Question 24

3 / 3 pts

Which part of the respiratory system is surrounded by capillaries? Why? Your Answer: aveoli are surrounded by capillaries because this is where oxygen passes from air into the blood and C02 passes the blood into the lung The alveoli are surrounded by capillaries. This is where oxygen passes from the air into the blood and carbon dioxide passes from the blood into the lungs. Question 25

3 / 3 pts

Explain what helps to maintain constant temperature within the lungs. Why is it important for effective gas exchange? Your Answer: Incomplete ventilation maintains to maintain a canstant temperature within the lungs, the higher the temperature the greater the gas volume and the lower temperature the lower the gas volume. Incomplete ventilation helps to maintain a constant temperature within the lungs. The increased temperature allows for greater gas exchange. Question 26

4 / 4 pts

From widest to narrowest, the branches of the bronchial tree are: Correct! Primary bronchi, secondary bronchi, tertiary bronchi, bronchioles

Bronchioles, primary bronchi, secondary bronchi, tertiary bronchi Tertiary bronchi, secondary bronchi, primary bronchi, bronchioles Secondary bronchi, tertiary bronchi, primary bronchi, bronchioles Question 27

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
