Answers:
There are two ways by which your body compensates for the acidosis/alkalosis.
1) Through kidneys.
2) Through lungs.
During increased hum similar to heavily built exercise, near is assembly of lactic sharp because of anaerobic oxidation i.e., oxygen not up to scratch state. Your body compensates quickly by increasing the respiratory rate thereby flushing out carbon dioxide (which is acidic) and taking more oxygen to prevent anaerobic oxidation.
The body may also compensate for the acidosis by preventing bicarbonate excretion through kidneys. Bicarbonate neutralize the sharp.
