Break Down the Problem

1. Identify the question: What is the average value of the inspiratory reserve volume (IRV) in milliliters (mL)?
2. Evaluate the options provided: 1000 - 1100 mL, 1100 - 1200 mL, 2500 - 3000 mL, 500 mL.

Relevant Concepts

• Inspiratory Reserve Volume (IRV) is the maximum amount of air that can be inhaled after a normal inhalation. It varies slightly among individuals but has average values based on medical literature.

Analysis and Detail

1. Understanding IRV Values:
   • Typically, the average IRV for adults ranges from 1500 mL to 3000 mL.
   • Reviewing standard physiological references, IRV is commonly stated to be around 2000 - 3000 mL in healthy adults.
2. Evaluating Options:
   • 1000 - 1100 mL: too low
   • 1100 - 1200 mL: still low
   • 2500 - 3000 mL: fits within the typical range
   • 500 mL: too low

Verify and Summarize

• Given the analysis, the range of 2500 - 3000 mL aligns with known physiological data regarding inspiratory reserve volume.

Final Answer

The average inspiratory reserve volume averages 2500 - 3000 mL.
