Histolysis is the decay and dissolution of organic tissues or of blood.
[2] Origin: New Latin, from Greek ‘ιστος (histos) tissue + λυσις (lusis) dissolution from λυειν to loosen, dissolve.
The loss of organs or blood begins with cell death, which can be caused by a number of factors.
In frogs, the histolysis of the tail associated with metamorphosis is also associated with a lowering of the pH of the blood.
[3] Increases in histolysis has been found to correspond with the pupal phase of insect metamorphosis, wherein larval organs break down before the histogenesis of the adult tissues occur.
