anerobic respiration : a respiration that breaks glucose into oxygen, it produces lactic acid

When a period of exercise is over, lactic acid must be removed. The body's tolerance of lactic acid is limited.

Lactic acid is taken to the liver by the blood, and either:

oxidised to carbon dioxide and water, or

converted to glucose, then glycogen - glycogen levels in the liver and muscles can then be restored
