Granulation tissue is new connective tissue and microscopic blood vessels that form on the surfaces of a wound during the healing process. [1] Granulation tissue typically grows from the base of a wound and is able to fill wounds of almost any size. Examples of granulation tissue can be seen in pyogenic granulomas and pulp polyps.
Wound healing refers to a living organism's replacement of destroyed or damaged tissue by newly produced tissue. [1] In undamaged skin, the epidermis (surface, epithelial layer) and dermis (deeper, connective layer) form a protective barrier against the external environment.
