Consider the following situations for an adult human being -- I) The maximum amount of air that can be breathed out after a maximum inspiration is around 4500 ml. II) Tidal volume is 500 ml. III) Inspiratory reserve volume is 2500 ml. What would be the Expiratory reserve volume in that individual ?
Options
- A1500 ml
- B2000 ml
- C2500 ml
- D3000 ml
Correct answer
A. 1500 ml
Step-by-step solution
Vital capacity is the maximum amount of air that can be breathed out after a maximum inspiration. VC = TV + IRV + ERV Given VC = 4500 ml, TV = 500 ml, and IRV = 2500 ml. Substituting the values: 4500 = 500 + 2500 + ERV ERV = 4500 - 3000 = 1500 ml. Answer: 1500 ml
