Question

If the inspiratory capacity of a human during forceful breathing is 3.5 litres and expiratory capacity
is 1.5 litres, then his vital capacity is
(A) 4.5 litres
(B) 5 litres
(C) 4 litres
(D) 5.4 litres
OA​

Answer 1

The vital capacity is equal to 5.4 litres.

This is the total of the  inspiratory capacity, exploratory capacity and the tidal volume= 3.5 +1.5 +0.5 litre = 5.5 litre

Option b.

Explanation:

• the tidal volume of a human being is roughly equal to 400 to 500 ml. This lung volumes and capacities are essential in detection of the  functional capacity of the lungs.

• in addition to this there is another essential parameter which is the residual function which helps in the determination of the amount of Air which is present in the long even after expiration. With decrease in  residual volume there can be increased in the obstructive lung diseases such as COPD
