Anaerobic Respiration produces lactic acid through a process known as "lactic acid fermentation."
The liver converts lactic acid to glucose, which it then can convert to glycogen for storage.

Liver
Answer: Lactic acid gets into our muscle through lactic acid fermantation. Fermantation is getting a cell energy without using oxygen.
After a while of swimming, your muscles use lactic acid. It uses it through Lactic acid fermentation. It results in more energy.
No, it is not. It's a normal biproduct of anaerobic respiration. After physical exercise the liver converts the lactic acid back to pyruvate which allows it to continue with cellular respiration.
It is generally accepted that epinephrine promotes the breakdown of muscle glycogen to lactic acid and that this lactic acid is largely reconverted to glycogen by the liver.
liver, lungs, heart.. balls.
The liver will extract lactic acid from the blood stream and convert it into glycogen, a reserve fuel type of energy.
