Question

Tidal volume and expiratory reserve volume of an athlete is 500 mL and 1000 mL, respectively. What will be his expiratory capacity if the residual volume is 1200 mL?

• A. 1500ml
• B. 1700ml
• C. 2200ml
• D. 2700ml

Answer 1

The correct option is A

1500ml

The correct option is A.

Explanation of the correct option:

Option A:

1. The amount of air that flows through the lungs during each respiratory cycle is known as the flowing volume. It is around 500 mL in a healthy, solid adult male and 400 mL in a healthy, sound female.
2. The definition of what constitutes optimal ventilation is a crucial clinical limit. The maximum amount of air that can be exhaled once resting motivation has ended is known as the expiratory limit. Tidal volume and expiratory save volume are equal to the term "expiratory limit."
   Tidal Volume = 500ml
   Expiratory Reserve Volume = 1000ml
   Expiratory Capacity = TV+ERV
   = 500+1000
   = 1500ml.

Explanation of the incorrect options:

1. All other options are incorrect.

Final answer: Expiratory capacity of the athlete is 1500 ml.
