Question and answer
describe the anatomy and physiology of the skin in relation to skin breakdown and the development of pressure sores
The skin consists of two principal parts. The outer, thinner portion,which is composed of epithelium, is called the epidermis. It contains no blood vessels and renews itself every twenty eight days. [ The epidermis is attached to the inner, thicker, connective tissue part called the dermis and this houses an extensive networks of blood vessels that carry 8 to 10% of the total blood flow in a
resting adult.. Beneath the dermis is a subcutaneous (subQ) layer. This layer, also called the superficial fascia or hypodermis, consists of areolar and adipose tissues. This area contains energy storing fat cells and nutrients and protects the body from the cold Fibbers from the dermis extend down into the subcutaneous layer and anchor the skin to it. The subcutaneous layer, in turn, attaches to underlying tissues and organs. The skin is the largest organ of the body. In adults the skin covers an area of two square metres and makes up a sixth of our body weight. The skin serves several functions. It regulates our body’s temperature by sweating and also by regulating the blood flow through the skin. It protects our body from bacterial invasion. It contains nerve endings and receptors to help us detect touch, pressure and pain.Pressure ulceration occurs when the skin and underlying tissues are compressed for a period of time, between the bone and the surface,on which the patient is sitting or lying. Blood cannot circulate causing a lack of oxygen and nutrients to the tissue cells.Furthermore, the lymphatic system cannot function properly to remove waste products. If the pressure continues, the cells die and the area of dead tissue that result is called pressure damage. The amount of time this takes will vary, but may develop in as little as one hour in patients at greatest risk ]
