What is the average value of expiratory reserve volume in a healthy adult?
2500 mL to 3000 mL
1500 mL to 2000 mL
1000 mL to 1100 mL
1100 mL to 1200 mL
The extra amount of air that a person may forcibly exhale is known as the expiratory reserve volume (ERV). 1000 to 1100 mL on average make up this amount.
Option 3 is the correct answer.
