Total lung capacity
Functional residual capacity
Inspiratory capacity
Vital capacity
1. : TV + IRV + ERV
2. : TV + IRV
3. : ERV + RV
4. : TV + IRV + ERV + RV

Answer 1

1. : TV + IRV + ERV → Vital capacity

2. : TV + IRV → Inspiratory capacity

3. : ERV + RV → Functional residual capacity

4. : TV + IRV + ERV + RV → Total lung capacity

Step-by-step explanation:

TV (Tidal volume), IRV (Inspiratory reserve volume), ERV (Expiratory reserve volume) & RV (Residual volume) are known as static lung volumes.

Vital capacity, Inspiratory capacity, Functional residual capacity & Total lung capacity are known as static lung capacities and they are a combination of two or more static lung volumes.

1. : TV + IRV + ERV → Vital capacity

It is a measure of maximum quantity of air which can be expelled out of fully inflated lungs.

2. : TV + IRV → Inspiratory capacity

It is a measure of maximum amount of air which can be inspired into the lungs after normal expiration.

3. : ERV + RV → Functional residual capacity

It is a measure of air which is left inside the lungs after expiration during a normal breath.

4. : TV + IRV + ERV + RV → Total lung capacity

This is a measure of maximum amount of air that can be accommodated in our lungs.
