Question 1

What is Tidal Volume?

Answer 1

Tidal Volume is the amount of air which enters the lungs during normal inhibition at rest.

Question 2

What is Inspiratory Capacity?

Answer 2

The greatest volume of air that can be inhaled into the lungs.

Question 3

What is the Inspiratory Reserve Volume?

Answer 3

The additional amount of air that can be inhaled into the lungs after normal inhalation.

IC=TV+IRV

Question 4

What is Expiratory Capacity?

Answer 4

The greatest volume of air that can be exhaled out of the lungs.

Question 5

What is the Expiratory Reserve Volume?

Answer 5

The additional amount of air that can be exhaled out of the lungs after normal exhalation.

EC=TV+ERV

Question 6

What is Vital Capacity?

Answer 6

Maximum amount of air that can be expelled from the lungs after a maximum inhalation.

VC=IC+ERV
VC=EC+IRV
VC=IRV+TV+ERV

Question 7

What is Total Lung Capacity?

Answer 7

The volume of air contained in the lungs at the end of maximal inspiration.

Question 8

What is Residual Volume?

Answer 8

The volume of air still remaining in the lungs after the maximal expiration.

RV=TLC-VC
