Sabiston, 18/e p2135 (17/e p2185); Schwartz 9/e p165))" Skin grafts to survive in the recipient bed, have to become revascularized. This takes place in three distinct phases":Imbibition: refers to absorption of nutrients into the graft, which serves to feed the graft for the first 24 to 48 hrs.Inosculation: is the process whereby donor and recipient capillaries become aligned. During the first two phases, the graft becomes adhered to the recipient bed by fibrous deposition at the interface.Revascularization : is completed by differentiation of the connecting vessels into arterioles and venules.', 'role': 'assistant'}]
