Volume of air that will remain in the lungs after a normal expiration is about:

1. 1200 ml

2. 2300 ml

3. 4600 ml

4. 5800 ml

Study the spirograph and identify the correctly matched volumes from the codes given:

         TV        IRV     ERV       RV      VITAL CAPACITY
1.       A          c         B          D              E
2.       A          B        C          D               E
3.       B          A        C          D               E
4.       C          B        A          D               E

Lungs are made up of air-filled sacs, the alveoli. They do not collapse even after forceful expiration, because of

1. Residual Volume (RV)

2. Inspiratory Reserve Volume (IRV)

3. Tidal Volume (TV)

4. Expiratory Reserve Volume (ERV)

What is vital capacity of our lungs?

1. Inspiratory reserve volume plus tidal volume

2. Total lung capacity minus expiratory reserve volume

3. Inspiratory reserve volume plus expiratory reserve volume

4. Total lung capacity minus residual volume

The volume of 'anatomical dead space’ air is normally

(1) 230 mL

(2) 210 mL

(3) 190 mL

(4) 150 mL.

Assertion            :       Vital capacity is higher in athletes than non-athletes.

Reason              :       Vital capacity is about 3.5-4.5 litres in a normal adult person.

Which of the following volume of air cannot be measured by respirometer?
(1)IRV

(2)ERV

(3)RV

(4)Both A and B

Volume of air which does not participate in gaseous exchange is
(1)Residual volume

(2)Dead space air

(3)Tidal volume

(4)Both A and B

The volume of air expired normally after forceful inspiration
1. TV+ IRV
2. TV+ERV
3. TV
4. None of these

The volume of air expired forcefully after normal inspiration
1. TV+ IRV
2.TV+ERV
3.TV
4. None of these
