FAQs on Respiratory Volumes- Breathing and Exchange of gases, Biology, Class 11 Video Lecture

1. What are respiratory volumes?

Ans. Respiratory volumes refer to the different measurements used to quantify the amount of air involved in breathing. These measurements include tidal volume, inspiratory reserve volume, expiratory reserve volume, and residual volume.

2. How is tidal volume defined?

Ans. Tidal volume is the volume of air inhaled or exhaled during a normal breath. It represents the amount of air that moves in and out of the lungs with each breath and is typically around 500 milliliters in healthy adults.

3. What is inspiratory reserve volume?

Ans. Inspiratory reserve volume is the additional volume of air that can be inhaled forcefully after a normal inhalation. It represents the maximum amount of air a person can take in beyond their normal tidal volume and is usually around 3000-3300 milliliters.

4. How is expiratory reserve volume calculated?

Ans. Expiratory reserve volume is the additional volume of air that can be exhaled forcefully after a normal exhalation. It is calculated by subtracting the tidal volume and inspiratory reserve volume from the total lung capacity. The average expiratory reserve volume is around 1000-1200 milliliters.

5. What is residual volume?

Ans. Residual volume is the volume of air that remains in the lungs even after a forceful exhalation. It is necessary to keep the lungs inflated and prevent them from collapsing. Residual volume averages around 1200-1500 milliliters and cannot be measured directly through spirometry.
