Best Answer

This is the amount of oxygen that is reserved in your body while you work out. The more that you work out the more of a reserve volume your body will have.

Why does eRV decrease during exercise?

Inspiratory Reserve Volume is the excess volume above the tidal volume that can be inspired. During exercise, there is an increase in demand for oxygen which leads to a decrease in IRV.

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 exercise generate H plus?

during exercise ATP is hydrolyzed and a hydrogen ion is released. ATP-derived hydrogen ions are responsible primarily for the decrease in pH
