NEET Solved Paper 2019 Question 27
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? [NEET 5-5-2019]
Options:
A) 2200 mL
B) 2700 mL
C) 1500 mL
D) 1700 mL
Show Answer
Answer:
Correct Answer: C
Solution:
*Expiratory Capacity (EC) is the total volume of air that can be exhaled after a normal inhalation. It is the sum of Tidal Volume (TV) and Expiratory Reserve Volume (ERV).
Given:
- Tidal Volume (TV) = 500 mL
- Expiratory Reserve Volume (ERV) = 1000 mL
Expiratory Capacity (EC) can be calculated as: [ \text{EC} = \text{TV} + \text{ERV} ]
Substituting the given values: [ \text{EC} = 500 , \text{mL} + 1000 , \text{mL} ] [ \text{EC} = 1500 , \text{mL} ]
Therefore, the Expiratory Capacity of the athlete is 1500 mL.
