Vital capacity of lungs is

Question

Vital capacity of lungs is (A) IRV + ERV (B) IRV + ERV + TV - RV (C) IRV + ERV + TV + RV (D) IRV + ERV + TV

Tardigrade Admin · Accepted Answer

Vital capacity is the maximum volume of air a person can breathe in after a forced expiration or the maximum volume of air a person can breathe out after a forced inspiration. This equals the inspiratory reserve volume (IRV) + expiratory reserve volume (ERV) + tidal volume (TV). Its value is 3400 mL - 4800 mL.
