Question

Tidal Volume and Expiratory Reserve Volume of an athlete is 500mL and 1000mL, respectively. What will be his Expiratory Capacity if the Residual Volume is 1200mL?
A. 1500 mL
B. 1700mL
C. 2200mL
D. 2700mL

Answer 1

Four standard lung volumes, in particular, Tidal volume (TV), inspiratory reserve volume (IRV), expiratory (ERV), and residual volumes (RV) are depicted in the writing. On the other hand, the standard lung limits are inspiratory (IC), practical or functional leftover (FRC), indispensable or vital (VC) and all out lung limits (TLC).

Complete answer:
Flowing volume is the measure of air that moves in or out of the lungs with each respiratory cycle. It measures around 500 mL in a normal solid grown-up male and roughly 400 mL in a sound female. It is a fundamental clinical boundary that considers appropriate ventilation to occur. The expiratory limit is the maximal volume of air that can be breathed out after finished resting motivation. Expiratory limit is equivalent to the amount of Tidal volume and expiratory save volume.
Tidal Volume = 500ml
Expiratory Reserve Volume = 1000ml
Expiratory Capacity = TV+ERV
= 500+1000
= 1500ml.

So, the correct answer is '1500 mL' option (A).

Additional Information:
Lung volumes and lung limits allude to the volume of air in the lungs at various periods of the respiratory cycle. The normal all out lung limit of a grown-up human male is around 6 liters of air. Flowing breathing is typical, resting breathing; the flowing volume is the volume of air that is breathed in or breathed out in just a solitary such breath.
The normal human respiratory rate is 30–60 breaths for each moment upon entering the world, diminishing to 12–20 breaths for every moment in grown-ups. Lung limits can be extended through adaptability activities, for example, yoga, breathing activities, and actual movement.

Note:
A more prominent lung limit is looked for by individuals, for example, competitors, athletes, free jumpers, artists, and wind-instrument players. A more grounded and bigger lung limit permits more air to be breathed in into the lungs. In utilizing lungs to play a breeze instrument for instance, breathing out an extended volume of air will give more prominent control to the player and consider a clearer and stronger tone.
