PATHOLOGY

Detailed explanation-1: -In case of regeneration, the damaged or lost tissue is replaced by the proliferation of surrounding undamaged cells and tissue. The normal structure of the tissue is restored or complete regeneration occurs in epidermis, GI tract epithelium and hematopoietic system where the cells have high proliferative capacity.

Detailed explanation-2: -Regeneration is replacement of destroyed tissue with the same type of tissue. Fibrosis is the proliferation of fibrous connective tissue otherwise called scar tissue. The first step in tissue repair is inflammation.

Detailed explanation-3: -Tissue regeneration is a part of the organism’s tissue that is traumatized by external forces and partially lost. Based on the remaining part, it grows the same structure and function as the lost part. This repair process is called tissue regeneration.

Detailed explanation-4: -Regeneration refers to a type of healing in which new growth completely restores portions of damaged tissue to their normal state.

Detailed explanation-5: -When cells become damaged or die the body makes new cells to replace them. This process is called cell division. One cell doubles by dividing into two. Two cells become four and so on.
