Residual Volume (rv) is important because it prevents the lungs from collapsing. It also prevents the inside surfaces of the lungs touching, thus creating friction. It also prevents the inner surfaces of the lungs sticking together.
Another reason why we have a residual volume is that gaseous exchange is continuously occurring so after we have expelled as much air as possible (expiratory reserve volume) gaseous exchange is still occurring.
Residual volume can be shown in this equation:
residual volume = inspiratory reserve volume - tidal volume - expiratory reserve volume
for an average person residual volume will be around 1 to 1.5 litres.

A residual volume is important, cause it keeps the alveoli open for further gaseous exchange.
It is also helpful in maintaining the proper respiration in the body of a person if he/she gets cut off from oxygen supply.
And we can even say that according to osmosis the molecules travels from high concentrated area to low concentrated area for that purpose there should be a regular opening in exchanging site. For that reason this air (residual volume) is present in the lungs which never allows the alveoli to close.

The air remaining in the lung after a maximal expiration is the?
residual volume
What is the functional residual capacity FRC composed of?
Functional Residual Capacity (FRC) = Expiratory Reserve Volume (ERV) + Residual Volume (RV)
What volume allows gas exchange to go on continuously?
Residual volume allows gas exchange to go on continuously
What is the function of residual volume?
The function of residual volume is to keep enough pressure in the lungs to keep them from collapsing.
How much residual should you get from a g tube?
Residual volume from a gastrostomy tube (G-tube) should be checked before feeding to ensure it is less than a specified amount (usually 100-200 mL) as a large residual volume may indicate feeding intolerance or gastric retention. If the residual volume exceeds the defined threshold, it is important to follow the healthcare provider's instructions on how to proceed with feeding.
What is residual volume of air?
Residual volume of air is the volume of air remaining in the lungs after maximal exhalation. It is not possible to voluntarily exhale this air, as it helps to keep the lungs inflated and prevents them from collapsing. Residual volume plays a key role in maintaining the oxygen-carbon dioxide exchange in the lungs.
Which volume of air is not included in the vital capacity?
residual (reserve) volume
What type of air is residual volume?
Residual volume is the air that remains in the lungs after a maximal exhalation. It is considered a type of "stale" or stagnant air that cannot be voluntarily expelled and helps keep the lungs inflated.
What is total residual volume?
It's (RV) = 1.2...
What is rvs lab test?
residual volume specimen
Why is functional residual capacity measured and why is it important?
Funtional Residual Capacity amounts
Why is it important that they look after the residual powers?
Residual power can build up and overcome.
