Question:

What is the normal Tidal Volume (TV) in a healthy adult human?

Show Hint

Important lung volumes: Tidal Volume (TV) → \( \approx 500\,mL \) Inspiratory Reserve Volume (IRV) → \( \approx 2500 - 3000\,mL \) Expiratory Reserve Volume (ERV) → \( \approx 1000 - 1100\,mL \)

The Correct Option is B

Solution and Explanation

Concept: Tidal Volume (TV) is the volume of air that is inhaled or exhaled during a normal breath when a person is at rest. It is one of the important parameters used to measure lung function.

Step 1:
Define tidal volume. Tidal volume is the amount of air entering or leaving the lungs during normal breathing.

Step 2:
State the normal value. In a healthy adult human, the normal tidal volume is approximately \[ 500 \text{ mL} \]

Step 3:
Select the correct option. \[ \boxed{500 \text{ mL}} \]
