Answer 27

right

Question 28

Question 30

name of membranes around the lungs

Answer 30

visceral and pariatal

Question 31

main thing that maintains breathing rate

Answer 31

CO2

Question 32

how many blood pathways go to the lungs

Answer 32

2

Question 33

what is the surfactant

Answer 33

fluid that is in the alveoli to keep the alveoli from sticking together

Question 34

ventilation is breathing, but what gets air into the lungs

Answer 34

when the chest cavity gets bigger, it creates a vacuum in the cavity. the pressure inside decreases, and is less that outside, so the air moves in

Question 35

predominant way that CO2 moves through the blood

Answer 35

bicarbonate anion

Question 36

what can be done to increase vital capacity

Answer 36

exercise

Question 37

if blow out all air, what is the little bit left called

residual volume

Question 38

why does oxygen and carbon dioxide move

Answer 38

diffusion

Question 39

true or false...Gas exchange in the respiratory zone will increase when increase the fluid in the alveoli

Answer 39

false...too much fluid in the alveoli, then it slows things down

Question 40

true or false...rate of gas exchange will increase if membrane is thicker

Answer 40

false...thicker membrane slows it down

Question 41

true or false...gas exchange rate will increase with more surface area

Answer 41

true...the more functional alveoli there are, the more oxygen- carbon-dioxide exchanged at a time

Question 42

how does carbon monoxide effect red blood cells

Answer 42

it sticks to hemoglobin so oxygen can't, causing you to suffocate

Question 43

what disease results in a decrease in surface area because some alveoli have been destroyed

Answer 43

emphysema

Question 44

main way oxygen moves in red bllod cells

Answer 44

in the blood on hemoglobin
