Respiratory Test

Question 1

What are the four main processes of respiration?

Answer 1

Pulmonary ventilation, external respiration, transport of respiratory gasses, and internal respiration

Question 2

What is internal respiration?

Answer 2

The exchange of oxygen and CO2 between body cells and blood in the capillaries

Question 3

What is the exchange of oxygen and CO2 between body cells and blood in the capillaries called?

Answer 3

Internal respiration

Question 4

What is the transport of respiratory gases?

Answer 4

When blood transports CO2 to the lungs and oxygen to the body’s cells

Question 5

What is pulmonary ventilation?

Answer 5

Inspiration and expiration in response to changes in oxygen and carbon dioxide in the body

Question 6

What is it called when blood transports CO2 to the lungs and oxygen to the body’s cells?

Answer 6

Transport of respiratory gases

Question 7

What is inspiration and expiration in response to changes in oxygen and carbon dioxide in the body called?

Answer 7

Pulmonary ventilation

Question 8

What is external ventilation?

Answer 8

The exchange of oxygen and CO2 between alveoli/blood in the pulmonary capillaries

Question 9

What is the exchange of oxygen and CO2 between alveoli/blood in the pulmonary capillaries called?

Answer 9

External respiration

Question 10

What does boyle’s law state?

Answer 10

That volume changes lead to pressure changes which then lead to the flow of gasses

Question 11

What law states that volume changes lead to pressure changes which then lead to the flow of gasses?

Answer 11

Boyle’s law

Question 12

Describe inspiration

Answer 12

The diaphragm moves inferiorly, intercostal muscles lift the ribcage, and pressure decreases

Question 13

What is inspiration?

Answer 13

Inhalation

Question 14

What do intercostal muscles do?

Answer 14

They lift the ribcage during inspiration

Question 15

When is there lower pressure in the lungs?

Answer 15

During inspiration

Question 16

What does the diaphragm do during inspiration?

Answer 16

It moves inferiorly

Question 17

What is expiration?

Answer 17

Exhalation

Question 18

Describe expiration

Answer 18

It normally depends on lung elasticity, not muscle contraction

Question 19

What depends on lung elasticity?

Answer 19

Expiration

Question 20

Is breathing a positive or negative pressure system?

Answer 20

It’s a negative pressure ventilation system

Question 21

What do the pleurae in general do?

Answer 21

They keep the lungs from separating or sticking

Question 22

What is airway resistance?

Answer 22

It’s the friction versus the cross sectional area

Question 23

What does alveolar surface tension do?

Answer 23

It tries to decrease alveolar size

Question 24

What prohibits lung collapse?

Answer 24

Surfactant

Question 25

What does surfactant do?

Answer 25

It prohibits lung collapse

Question 26

What is lung compliance?

Answer 26

The stretchiness of lungs

Question 27

What does the stretchiness of the lungs include?

Answer 27

Defensibility and alveolar surface tension

Question 28

What measures the stretchiness of the lungs?

Answer 28

Lung compliance

Question 29

How does oxygen bind with red blood cells?

Answer 29

Oxygen binds with the heme's iron in red blood cells

Question 30

What does oxygen bind with?

Answer 30

It binds with the heme's iron in red blood cells

Question 31

What is the plurae?

Answer 31

The surface of the lungs and diaphragm

Question 32

How does the plurae help the lungs inflate?

Answer 32

The muscles pull on the visceral plurae, which then pulls on the fluid and on the parietal plurae.

Question 33

What does the plurae do?

Answer 33

It inflates the lungs by reestablishing a vacuum

Question 34

What is the average vital capacity?

Answer 34

4800ml

Question 35

What is the average lung capacity?

Answer 35

5,500

Question 36

What is the average tidal volume?

Answer 36

500

Question 37

What does an increased temperature do?

Answer 37

It decreases the affinity for oxygen

Question 38

What does a decreased pH do?

Answer 38

It decreases the affinity for oxygen

Question 39

What does a decreased temperature do?

Answer 39

It increases the affinity for oxygen

Question 40

What does an increased pH do?

Answer 40

It increases 02 affinity

Question 41

Is temperature directly or inversely proportional to oxygen affinity?

Answer 41

Inversely

Question 42

Is pH directly or inversely proportional to oxygen affinity?

Answer 42

Directly

Question 43

Is CO2 partial pressure directly or inversely proportional to oxygen affinity?

Answer 43

Inversely

Question 44

Is BPG directly or inversely proportional to oxygen affinity?

Answer 44

Inversely
