Detailed explanation-1: -Regeneration is the natural process of replacing or restoring damaged or missing cells, tissues, organs, and even entire body parts to full function in plants and animals. Scientists are studying regeneration for its potential uses in medicine, such as treating a variety of injuries and diseases.

Detailed explanation-2: -The liver is the only organ in the human body that can regenerate. Although some patients who have a diseased portion of their liver removed are unable to regrow the tissue and end up needing a transplant. Researchers from Michigan State University believe blood clotting factor fibrinogen may be responsible.

Detailed explanation-3: -Regeneration means the regrowth of a damaged or missing organ part from the remaining tissue. As adults, humans can regenerate some organs, such as the liver. If part of the liver is lost by disease or injury, the liver grows back to its original size, though not its original shape.

Detailed explanation-4: -There are three types of regen options: passive, active and manual.

Detailed explanation-5: -In humans, the natural ability to regenerate is limited to tissues like the epidermis, the outermost layer of skin, and some organs, such as the liver. Other species, most notably salamanders, have the ability to regenerate complex structures such as bones, joints, and even entire limbs.
