Consider the following statements each with two blanks.
(i) Actually, only about `overset((1))"_____"` mL of air enters the lungs alveoli for the exchange of gases. The remaining fills the respiratory passage and is termed `overset((2))"_____"`.
(ii) The amount of air which one can inhale with maximum effort and also exhale with maximum effort is termed as `overset((3))"_____"`. It is about `overset((4))"_____"` in normal adult person.
(iii) During normal quiet breathing, on an average, approximately `overset((5))"_____"` mL of air is inspired or expired by adult human male in each breath. It is termed as `overset((6))"_____"` volume.
Which of the following options gives the correct fill ups for the respective blanks numbers from (1) to (6) in the above statement ?

Options

A. `(3)`-vital capacity, `(4)-4000` mL, `(5)-500, (6)-`tidal
B. `(1)-100`, `(2)`-residual volume, `(3)-`functional residual capacity, `(4)-3000 mL`
C. `(1)-350`, `(2)`-dead space air, `(5)-1000, (6)`-inspiratory reserve
D. `(1)-350`, `(2)`-residual volume, `(3)-`vital capacity `(4)-4000 mL`

Answer

A

Explanation

Actually, only about `350` mL of air (out of total `500` mL tidal volume) enters the lung alveoli for the exchange of gases. The remaining `150` mL fills the repiratory passage and is termed as dead air space because no exchange of gases takes place here.
