A

A

18

B. Allows passage of fluid and oxygen

C. Allows communication between adjacent alveoli

D. All of the above

A

D

19
Q

A. Type 1, Structure

B. Type 1, Macrophage

C, Type 2, Surfactant

D. Type 3, Macrophage

E. Type 3. Surfactant.

A

A, C, D

Type1= structure

Type2= surfactant

Type3= macrophage

20
Q

A. Phospholipid liquid made by type II cells used to enhance anatomic stability of the lungs

B. Used for medicinal distribution in the lungs

C. Used for mucociliary transport of substances out of the lungs

D. Phospholipid liquid made by type III cels used to enhance anatomic stability of the lungs.

A

A

21
Q

The major components of Asthma include: (Select All)

A. Inflammation

B. Hyporesponsiveness

C. Airflow obstruction

D. Hyperresponsiveness

E. Bronchodilation

A

A,C, D

Hyperresponsiveness and inflammation can lead to airflow obstruction. Airflow obstruction is the last thing that happens.

22
Q

T/F People from third-world countries will have a lower risk for asthma than people in modernized countries.

A

T

23
Q

What is the purpose of T-Helper 1 cells?

A

Phagocytosis of foreign invaders.

24
Q

What is the purpose of T-Helper 2 cells?

A

Upregulates during times of exposure when dendritic cells activate them. They elicit inflammatory response, increase cytokine production and IgE synthesis.

25
