Which of the following organ in the human body is able to regenerate on its own?

In some organisms,  regeneration takes place to regenerate a lost or cut body part. It is carried out by specialised cells that proliferate and form a mass of cells that eventually differentiate to form various cell types and tissues.

In the human body, the liver is the only organ that possesses the tendency to regenerate itself post-destruction. If 70-80 percent of liver tissue is removed it can regenerate itself nearly to its original size within 4-5 months.
