DEGREE OF TISSUE REPAIR Damaged tissues are repaired continually Depending on the type and location of injury, some tissues are repaired quickly © 2004 Delmar Learning, a Division of Thomson Learning, Inc.

PROCESS OF EPITHELIAL TISSUE REPAIR There are two types of epithelial tissue repair: Primary repair involves skin where there is no infection present Secondary repair occurs in large, open wounds with tissue loss © 2004 Delmar Learning, a Division of Thomson Learning, Inc.
