What are the effects of exercise on the expiratory reserve volume?

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.


How do you do capacity?

It's the inspiratory reserve volume plus the tidal volume plus the expiratory reserve volume


Calculate the IRV of a person with an active capacity of 4360ml an expiratory reserve volume of 1300ml and a tidal volume of 500ml?

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.


What are the volumes that makes up vital capacity?

Expiratory reserve volume, tidal volume, inspiratory reserve volume, you amateurs


What are the three volumes that make up vital capacity?

Expiratory reserve volume, tidal volume, inspiratory reserve volume, you amateurs


calculate the IRV of an individual with a vital capacity of 4400 ml an expiratory reserve volumne of 1300 ml and a tidal volume of 500ml?

2600 ml


How do you calculate tidal volume in a cat?

Tidal volume is the total amount of air in your lungs that is inhaled/exhaled at one point. Tidal volume is found by using a machine to calculate it. Or, it is:Insiratory reserve volume+expiratory reserve volume+tidal volume+residual volume.REVISIONYour definition of tidal volume is correct...it is the amount of air that moves in or out of the lungs during normal inspiration or expiration, but the equation you gave (IRV + Vt +ERV + RV) is for Total Lung Capacity.I don't believe that there is an equation to calculate tidal volume. It can be calculated, however, by subtracting your average ERV (expiratory reserve volume) from your average EC (expiratory capacity). Using a spirometer, perform the procedure to get your expiratory capacity. Do this 3 times and figure the average. Then perform the procedure to get your expiratory reserve volume and repeat 3 times to figure your average. Then, as I mentioned in the 1st line of this paragraph, subtract your average ERV from your average EC.


How does expiratory reserve volume change with exercise?

What happens to residual volume, tidal volume, inspiratory reserve volume and expiratory reserve volume just after exercise while breathing deeply and rapidly? Do they increase, decrease or stay the same?


What is FRV an abbreviation for?

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.


What is The volume of air that can be exhaled after a maximum inhalation?

Vital Capacity (VC) is the maximum amount of air that can be exhaled after a maximum inhalation. But it differs from one person to another. For a normal sized male that would be 4600 ml.


What is the functional residual capacity FRC composed of?

Functional Residual Capacity (FRC) = Expiratory Reserve Volume (ERV) + Residual Volume (RV)


What does ERV in respiratory system mean?

The ERV is the expiratory reserve volume, which is the amount of air that can be forcefully exhaled after a normal tidal volume exhalation.
