The volume not included in the vital capacity is the residual volume (RV). Residual volume is the amount of air that remains in the lungs after a maximal exhalation and cannot be voluntarily expelled. Vital capacity, which consists of tidal volume, inspiratory reserve volume, and expiratory reserve volume, measures the maximum amount of air a person can exhale after a deep breath, excluding the residual volume.
Volume of a cylinder = (pi) x (radius of the end)2 x (length)
Density is the amount of mass per unit of volume. Density = mass/volume Mass is the amount of matter in a sample. Length is the longest extent of anything as measured end to end. Volume is the amount of three-dimensional space occupied by a solid, liquid, or gas.
A good place to measure is the diameter of the circular end. That gives you the area of the circular end, and the only other number you need in order to calculate the cylinder's volume is its straight length.
The volume of any cylinder is (pi) x (radius of the circular end)2 x (length of the cylinder)
Regular exercise can increase the strength and efficiency of respiratory muscles, including those involved in exhalation. This can lead to improved lung function, increased expiratory muscle strength, and potentially an increase in expiratory reserve volume over time.
ACUTE EFFECT - The inspiratory and expiratory volume decreases during exercise
The abbreviation FRV stands for functional reserve volume. Functional reserve volume is used to describe the volume of air in ones lungs at the end of the expiratory position.
Forced expiratory volume
It's the inspiratory reserve volume plus the tidal volume plus the expiratory reserve volume
Erv = FEV - TV

The Inspiratory reserve volume (IRV) is calculated by subtracting the tidal volume and expiratory reserve volume from the total lung capacity. In this case, the total lung capacity is the sum of the active capacity and the expiratory reserve volume, which equals 5660ml. Therefore, the IRV would be 5660ml - 500ml - 1300ml = 3860ml.
During exercise, expiratory reserve volume decreases because more air is being exhaled to help meet increased oxygen demands. The respiratory rate and depth of breathing typically increases during exercise, which can lead to a decrease in expiratory reserve volume.
