Steps in Integument repair and regeneration
Cut blood vessel bleeds into the wound
Blood clot forms, leukocytes cleans wound
Blood vessels regrow, granulation tissue forms
Epithelium regenerates and connective tissue fibrosis occurs
Tissues in Subcutaneous Layer
Areolar Connective Tissue- hold organs in place and attaches epithelial tissue to other underlying tissue
Adipose Connective Tissue- loose connective tissue composed of adipocytes
Two layers of the Dermis
Papillary Layer- superficial region of dermis that houses sensory receptors
Reticular Layer- deep region of the dermis that is a network of collagen fibers
