Is the Tidal Volume (TV) greater than the Inspiratory Reserve Volume (IRV) in healthy adults?

Options

  1. AYes
  2. BNo
  3. CCannot be determined
  4. DDepends on the individual

Correct answer

B. No

Step-by-step solution

Tidal Volume (TV): Volume of air inspired or expired during a normal respiration . It is approx. 500 mL., i.e., a healthy man can inspire or expire approximately 6000 to 8000 mL of air per minute. Inspiratory Reserve Volume (IRV): Additional volume of air, a person can inspire by a forcible inspiration . This averages 2500mL to 3000 mL.
