[9/1, 20:20] pillairohit1991: One good way to remember this: Take a deep breath in upto your maximum capacity. Now there is approximately 6 litres of air in your lungs. That is your Total lung capacity. Now breathe out as deep as you can. You just breathed out 4800 mls of air. That is your vital Capacity. But even after breathing out completely, 1200 mls of air is still reserve in your lungs. That is your residual volume. Now breathe normally. In your normal breathing, approximately 500 mls of air is going in and out. That is your tidal volume. Now breathe normally like in tidal Volume. Now after a normal tidal volume inhalation happens breathe in effortfully to your maximum capacity. You just breathed in 3200 mls of air over your tidal volume. That is your Inspiratory Reserve Volume. So basically your Tidal Volume was already 500 mls. On the top of that you further breathed in 3200 mls. So that becomes a total of 3700 mls which is your actual Inspiratory c...
