Respiratory System

Question 1

Airway Function

Answer 1

Allow air to enter and exit

Question 2

Lung function

Answer 2

Gas exchange

Question 3

Rib cage function

Answer 3

protects the lungs

Question 4

Functions of the respiratory system

Answer 4

1) Gas exchange
2) Increase temp of air going in the lungs
3) increase humidity of the air
4) Filter the air entering the lungs

Question 5

Why does the respiratory system increase the humidity and temp of the air?

Answer 5

Helps with gas exchange

Question 6

What are the intercostal muscles

Answer 6

The muscles in between the ribs

Question 7

What are the bronchi

Answer 7

main branches in the airways in the lungs

Question 8

what are Bronchioles

Answer 8

Branches of the bronchi

Question 9

What are alveoli

Answer 9

air sacs at the end of the bronchi where gas exchange occurs

Question 10

what is the visceral pleura

Answer 10

innermost Thin membrane covers the surface of the lungs

Question 11

What is the parietal pleura

Answer 11

The outermost membrane covers the lungs. produces the fluid that exists between the parietal and visceral pleura

Question 12

What fluid lines the airways

Answer 12

mucous

Question 13

what are goblet cells?

Answer 13

cells in the airways that store mucous.

Question 14

what are cialeted cells

Answer 14

• cells in the airways that increase the humidity of the entering air.
• bring NaCl and H2O into airways

Question 15

What force causes gas exchange to occur?

Answer 15

Partial pressure difference

Question 16

What are Squamous cells

Answer 16

cells in the alveoli that facilitate gas exchange

Question 17

What covers the squamous cells

Answer 17

Surfactant which reduces the surface tension with inspiration

Question 18

a compound in RBCs that carries oxygen

Answer 18

Hemoglobin (carries 4 O2)

Question 19

What is the diaphragm responsible for?

Answer 19

contracting and causing the pressure in the lungs to decrease or increase which causes air to flow in/ out

Question 20

the pressure of the water in between the Parietal and Visceral pleura follows the trend:

Answer 20

decreases as it goes further down the lungs ( Avg of 5 mmH2O)

Question 21

Tidal Volume (TV)

Answer 21

Amount of air moving through the lungs when the body is at rest.

Question 22

Expiration reserve volume (ERV)

Answer 22

amount of extra air above normal that is exhaled during a forceful breath out.

Question 23

Residual Volume (RV)

Answer 23

volume of air in the lungs after maximum forceful expiration

Question 24

Inspiration reserve volume (IRV)

Answer 24

Maximum extra air a person can inhale forcefully above the tidal volume

Question 25

Vital Capacity (VC)

Answer 25

Amount of air that can be expelled from the lungs after maximum inhalation

Question 26

Total Lung Capacity (TLC)

Answer 26

Maximum volume of air the lungs can hold
