respiration

Question 1

tidal volume

Answer 1

volume of air inhaled and exhaled in a normal breath

Question 2

vital capacity

Answer 2

the grand come of all the air that can enter and exit the lungs except residual volume

Question 3

residual volume

Answer 3

gas that always remains in the lungs
- keeps the lungs from collapsing on themselves

Question 4

gases (exchange)

Answer 4

diffuse from areas of high to low levels of partial pressure

Question 5

ventilation

Answer 5

inhalation + exhalation

Question 6

capillary

Answer 6

• single cell thick
• surrounds alveolus
• where blood circulates

Question 7

external respiration

Answer 7

• in the alveoli
• oxygen enters the blood and CO2 diffuses from the blood into the alveolus

Question 8

red blood cells

Answer 8

• filled with hemoglobin which binds with O2 to create oxyhemoglobin

Question 9

oxyhemoglobin

Answer 9

• forms in red blood cells
• oxygen and hemoglobin
• releases O2 to the blood with in the tissues

Question 10

internal respiration

Answer 10

• within the tissues
• O2 leaves capillary for tissue cells
• CO2 diffuses from tissues to the capillaries of the blood

Question 11

CO2 disguising

Answer 11

• dissolved in plasma
• attaches to hemoglobin and forms carbaminohemoglobin

Question 12

medulla oblangata

Answer 12

• in the brain
• signals the diaphragm to increase the rate of inspiration and exhalation
• has chemoreceptors that are sensitive to low pH
• increases the rate of excretion of carbon dioxide

Question 13

carotid artery

Answer 13

uses chemoreceptors to deflect low O2
- slower than acid receptors

Question 14

volume of air inhaled and exhaled in a normal breath

Answer 14

tidal volume

Question 15

the grand sum of all the air that can enter and exit the lungs except residual volume

Answer 15

vital capacity

Question 16

gas that always remains in the lungs
- keeps the lungs from collapsing on themselves

Answer 16

residual volume

Question 17

diffuse from areas of high to low levels of partial pressure

Answer 17

gases (exchange)

Question 18

inhalation + exhalation

Answer 18

ventilation

Question 19

• single cell thick
• surrounds alveolus
• where blood circulates

Answer 19

capillary

Question 20

• in the alveoli
• oxygen enters the blood and CO2 diffuses from the blood into the alveolus

Answer 20

external respiration

Question 21

• filled with hemoglobin which binds with O2 to create oxyhemoglobin

Answer 21

red blood cells

Question 22

• forms in red blood cells
• oxygen and hemoglobin
• releases O2 to the blood with in the tissues

Answer 22

oxyhemoglobin

Question 23

• within the tissues
• O2 leaves capillary for tissue cells
• CO2 diffuses from tissues to the capillaries of the blood

Answer 23

internal respiration

Question 24

• dissolved in plasma
• attaches to hemoglobin and forms carbaminohemoglobin

Answer 24

CO2 disguising

Question 25

- in the brain - signals the diaphragm to increase the rate of inspiration and exhalation - has chemoreceptors that are sensitive to low pH - increases the rate of excretion of carbon dioxide

Answer 25

medulla oblangata

Question 26

uses chemoreceptors to deflect low O2 - slower than acid receptors

Answer 26

carotid artery
