The correct Answer is:
To find the Functional Residual Capacity (FRC), we need to use the formula: **Functional Residual Capacity (FRC) = Expiratory Reserve Volume (ERV) + Residual Volume (RV)** ### Step-by-Step Solution: 1. **Identify the given values**: - Expiratory Reserve Volume (ERV) = 1100 ml - Residual Volume (RV) = 1200 ml - Tidal Volume (TV) = 500 ml (not needed for this calculation) 2. **Use the formula for FRC**: - FRC = ERV + RV 3. **Substitute the values into the formula**: - FRC = 1100 ml + 1200 ml 4. **Perform the addition**: - FRC = 1100 ml + 1200 ml = 2300 ml 5. **Conclusion**: - The Functional Residual Capacity (FRC) is 2300 ml. ### Final Answer: The Functional Residual Capacity is **2300 ml**. ---
