Document Summary
Module 3 skin integrity, wound management and surgical asepsis. Part a: skin integrity and wound management: review the structure and functions of the skin. The skin guards the body from environmental stresses such as trauma, dirt and pathogens. The skin provides protection from injury from physical, chemical, thermal and light wave sources. It prevents penetration, perception, temperature regulation, identification, communication, wound repair, absorption and excretion and production of vitamin d. the skin has two layers. The outer layer is the epidermis and the inner supportive layer is dermis. The inner stratum germinativum forms new skin cells and its major ingredient is the tough and fibrous protein keratin. The dermis is the inner supportive layer consisting the most connective tissue. It enables the skin to resist tearing and allow the skin to stretch. The subcutaneous layer is adipose tissue, which is made up of lobules of fat cells.
