Answer 1

obstructive lung diseases

Question 2

example of obstructive lung diseases

Answer 2

chronic obstruction pulmonary disorder (COPD)

Answer 9

inspiratory capacity

Question 10

the total amount of air remaining in the lungs after a normal exhalation

Answer 10

functional residual capacity

Question 11

the total amount of air the lungs can contain

Answer 11

total lung capacity

Question 12

medical test used to measure the four lung volumes

Answer 12

spirometry

longer breath holding time

Answer 13

better pulmonary function
functional reserve
larger lung capacity

Question 14

respiratory system and cardiovascular system function to

Answer 14

take oxygen into body from atmospheric air and deliver it to tissue cells

Question 15

the rate at which you obtain oxygen from the environment

Answer 19

ventilation

Question 20

the rate at which oxygen is delivered to the body tissue cells through capillary walls

Answer 20

perfusion

Question 21

increase ventilation by

Answer 21

increasing respiratory depth (tidal volume) and respiratory rate

Question 22

increase perfusion

Answer 22

increase heart rate

Question 23

flow of air into and out of the lungs

Answer 23

minute volume (Vm)

Question 24

balance of exchange between ventilation and perfusion

Answer 24

ventilation-perfusion coupling

Question 25

increase or decrease in the rhythm, and rates of respiration is controlled by

Answer 25
