Lab Exam Respiratory System

Question 1

What is the Minute Volume formula?

Answer 1

Breathing rate * Tidal Volume

Question 2

Tidal volume

Answer 2

amount of air inhaled/exhaled with each breath under resting conditions

Question 3

Inspiratory Reserve Volume

Answer 3

amount of air that can be forcefully inhaled after a normal tidal volume inspiration

Question 4

Expiratory Reserve volume

Answer 4

amount of air that can be forcefully exhaled after a normal tidal volume expiration

Question 5

Residual Volume

Answer 5

amount of air remaining in lungs after a forced expiration

Question 6

Total Lung Capacity

Answer 6

max amount of air contained in lungs after max inspiratory effort
TLC = TV + IRV + ERV + RV

Question 7

Vital Capacity

Answer 7

max amount of air that can be expired after max inspiratory effort
VC= TV + IRV + ERV

Question 8

Inspiratory Capacity

Answer 8

max amount of air that can be inspired after a normal tidal vol expiration
IC = TV + IRV

Question 9

Functional Residual Capacity

Answer 9

volume of air remaining in lungs after normal tidal vol expiration
FRC = ERV +RV

Question 10

Average Tidal Vol

Answer 10

500 ML

Question 11

What tools are used to determine respiratory volumes?

Answer 11

spirometer

Question 12

What is a major factor effect levels of Oxygen and CO2 in alveoli?

Answer 12

alveolar ventilation

Question 13

What happens to Blood vessels when there is high levels of CO2?

Answer 13

Blood Ph falls and sensors in Major BV detect PH decrease and sends signals to the medulla which sends signals to rib muscles and diaphragm to increase the rate/depth of ventilation

Question 14

Alveolar ventilation formula

Answer 14

(Tidal vol - anatomic dead space) * breathing rate
