Oxygenation (adults)

Question 1

Lung compliance

Answer 1

the ease at which the lungs can be inflated

Question 2

Elastin fibers

Answer 2

easily stretched and make lung expansion easy

Question 3

Collagen fibers

Answer 3

resist stretching and makes lung expansion difficult

Question 4

Describe emphysema

Answer 4

overstretched lung tissue that causes elastin to lose recoil, allowing the lungs to inflate easily but difficult to deflate

Question 5

Surfactant

Answer 5

lowers surface tension, increases lung compliance, easy lung inflation

Question 6

Shunt

Answer 6

blood moves from the right to the left side of circulation without becoming oxygenated

Question 7

Restrictive pulmonary disease

Answer 7

problems with the inflow of air

Question 8

What is restrictive pulmonary disease caused by

Answer 8

decrease in the number of functional alveoli

Question 9

Common outcome of restrictive pulmonary disease

Answer 9

hypoxemia

Question 10

Obstructive pulmonary disease

Answer 10

problems with the outflow of air

Question 11

What is obstructive pulmonary disease caused by

Answer 11

air is trapped in alveoli, unable to completely empty before new air enters (CO2 is trapped) –> airway is narrowed

Question 12

When does cor pulmonale occur

Answer 12

obstructive pulmonary disease
