Document Summary
Decrease in size of tissue/organ caused by reduction in # /size of individual cells. Separation & disruption of previously joined wound edges. Abnormal differentiation of dividing cells that results in change in size, shape, appearance of cell. Protrusion of intestines through wound when wound edges separate to certain extent. Immature ct cells that migrate into healing site and secrete collagen. Abnormal passage between organs or hollow organ and skin. Increase in # cells as result of increased cellular division. Inappropriately large, red, raised, hard scar that remains confined to wound edges and regresses in time. Increase in size of cells that results in increased tissue mass w/o cell division. Sequential rxn to cell injury that neutralizes and dilutes the inflammatory agent, removes necrotic materials, establish environ suitable for healing and repair. Cell receptors that mediate attachment between endothelial cells and surrounding tissues, involve in leukocyte extravasation during immune response.
