Detailed explanation-1: -regeneration. … multiply throughout life, (2) the stable cells, which do not multiply continuously but can do so when necessary, and (3) the permanent cells, incapable of multiplication in the adult-only the permanent cells are incapable of regeneration.
Detailed explanation-2: -A few types of tissue are composed of cells that have left the cell cycle permanently, and are therefore unable to proliferate. These nondividing tissues (or permanent tissues) include cardiac and skeletal muscle. Tissue repair in these tissues always leaves permanent evidence of injury, such as a scar.
Detailed explanation-3: -The correct statement regarding tissue repair is C) Inflammation causes capillaries to dilate and become permeable. Inflammation is the first step of tissue repair and occurs soon after the injury.
Detailed explanation-4: -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. In the case of stable tissues like liver and kidney, compensatory growth occurs rather than true regeneration.
