The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Vital Capacity**: Vital capacity is defined as the maximum amount of air that can be expelled from the lungs after a maximum inhalation. It is an important measure in respiratory physiology. 2. **Components of Vital Capacity**: Vital capacity is the sum of three lung volumes: - **Inspiratory Reserve Volume (IRV)**: The maximum amount of air that can be inhaled after a normal inhalation. - **Tidal Volume (TV)**: The amount of air inhaled or exhaled during normal breathing. - **Expiratory Reserve Volume (ERV)**: The maximum amount of air that can be exhaled after a normal exhalation. Therefore, the formula for vital capacity (VC) is: \[ VC = IRV + TV + ERV \] 3. **Clarifying the Statement**: The statement in the question claims that "Vital capacity is a measure of maximum inspiration." This is misleading because vital capacity actually involves both inhalation and exhalation. 4. **Conclusion**: The correct interpretation is that vital capacity reflects the maximum amount of air that can be exhaled after maximum inhalation, not just maximum inspiration. Thus, the statement is false. 5. **Units of Measurement**: Vital capacity is typically measured in cubic centimeters (cc) or liters. **Final Answer**: The statement "Vital capacity is a measure of maximum inspiration" is false. Vital capacity is a measure of the maximum amount of air that can be expelled from the lungs after maximum inhalation. ---
