listed below are four respiratory capacities (A-D) and four jumbled respiratory volumes of a normal human adult
`{:("Respiratory capacities" , - " " "Respiratory volumes"),("Residual volume", -" " "2500 mL"),("Vital capacit",- " ""3500 mL"),("Inspiratory reserve volume",-" "1200 mL),("Inspiratory capacity", -" " 4500mL):}`
Which one of the following is the correct matching of two capacities and volumes

Options

A. (2)2500 mL.(3) 4500 mL
B. (3) 1200 mL.(4)2500 mL
C. (4) 3500 mL, (1) 1200 mL
D. (1) 4500 mL, (2) 3500 mL

Answer

C

Explanation

Inspiratiory capoacity (IC) is the maximum amount of air that can be inspired after a normal expiration .IC =TV+IRV. It is 3500 mL in adult male and 2400 mL inadult female.
Residual volume (RV) is ythe amount of air remaining in the lungs after of forced exhalation.OIts average value is 1200 mL and 1100 mL in adult male and female respectively.
