Undertake agreed pressure area care Unit 4222-229 Outcome 1: Describe the anatomy and physiology of the skin condition to skin breakdown and the development of pressure sores. Q1.1 Skin is the largest organ of the body, covering and protecting the entire surface of the body. The total surface area of skin is around 3000 sq inches or roughly around 19,355 sq cm depending on age, height, and body size. The skin, along with its derivatives, nails, hair, sweat glands, and sebaceous glands forms the integumentary system. Besides providing protection to the body the skin has a host of other functions to be performed like regulating body temperature, immune protection, sensations of touch, heat, cold, and pain through the sensory nerve endings, communicating with external openings of numerous other body systems like digestive system, urogenital system, and respiratory system via mucous membranes.The skin is primarily composed of three layers.
APA Style Sheet 1 Integumentary System Medical Assistant New Horizons Medical Institute Denise Harris LPN/ Instructor Jennifer Matthews/ Student May 8, 2012 APA Style Sheet 2 Abstract The largest organ of the body is the external covering known as the skin or the integumentary system. The skin is not usually classified as a body system but more classified as an organ. The integumentary system is the largest organ on the body including extensions of the skin as hair and nails. However, the skin is the most important of these. The skin provides a physical barrier to keep out foreign materials and prevent the body from drying out, while providing protection and a cushion to the body’s organs.
These types of glands are simple alveolar glands that are found all over the body except for areas likes the palms and soles. They are found to be quite small on the body trunk yet large on areas like the face, neck and upper chest. These glands secrete sebum which is an oily secretion. The central cells of the alveoli accumulate only lipids until they become so engorged that they burst which makes the sebaceous gland a holocrine gland. Sebum is secreted into areas like the hair follicles or the pores on the skin surface.
They are elongated and column shaped. The nuclei are elongated and and usually found towards the base of the cells. They form the lining of the stomach and intestines. They secrete mucus to keep the surface smooth. Ciliated Columnar Epithelium are simple columnar epithelial cells but they have fine, hair like cilia on their free surfaces.
2024 Undertake Agreed Pressure Area Care 1.1.1 The anatomy and physiology of the skin in relation to skin breakdown and the development of pressure sores. The skin is the largest organ of the body and it acts as a waterproof protector for all the internal organs and it consist of four distinct layers: The epidermis, the basement membrane zone, the dermis and the subcutaneous layer. The epidermis which is the outer layer and is a protective multilayered self renewing structure which varies in thickness depending on which part of the body it covers under this the dermis, this is a layer of connective tissue which provides the skins elasticity and strength, it also contains sensory nerve endings, blood and lymph vessels, sebaceous and sweat glands. Under this layer is the subcutaneous fat layer; this separates the skin from the underlying bone and muscle with rich blood supply it also serves as an insulator and energy store. Pressure ulcers develop when a large amount of pressure is applied to an area of skin over a short period of time.

Besides providing protection to the body the skin has a host of other functions to be performed like regulating body temperature, immune protection, sensations of touch, heat, cold, and pain through the sensory nerve endings, itself divided into epidermis, dermis, and subcutaneous layer or hypodermis. Each layer has it own function and own importance in maintaining the integrity of skin and thereby the whole body structure.

The skin is the largest organ of the body, covering and protecting the entire surface of the body. The total surface area of the skin is around 3000sq inches depending on age, height and body size. As well as the nails, hair, sweat glands and the sebaceous glands, the skin forms the integumentary system. Besides oroviding protection to the body, the skin also helps regulate body temperature, helps your immune system, provides sensations of touch, heat, cold and pain throught the sensory nerve endings.
P2 There are two different types of epithelial tissue these are simple and compound. Simple Epithelium- this type of epithelium tissue is from an animal consisting of one of more layers of closely packed cells. The cells can vary in structure depending on their function which may be protective, secretory or absorptive. This epithelium tissue covers external and internal surfaces of the body. Compound Epithelium – this type of epithelial tissue is made to withstand wear and tear.
Skin Cancer Antoniette Tucson AP2530 Mr. Torres 07/17/2015 ITT Technical Institute Skin Cancer There are many parts to the skin, and the skin has many functions. The skin is also part of the integumentary system which also includes hair, skin, skin glands, and nails. The layers of the skin are epidermis, dermis, and the hypodermis, also known as the subcutaneous layer. The skin has many functions such as regulates body temperature, stores blood, protects us form the external environment, detects sensations, excretes and absorbs substances and helps make vitamin D. Melanocytes transfer melanin which is a yellow-red or brown-black pigment, which contributes to skin color and also absorbs damaging ultraviolet light. Melanin, carotene, and hemoglobin are the three pigments that give skin a wide variety of colors.
Insect saliva inactivates blood components and manipulates host immunity The animal blood feeding is an essential event associated with the life cycle of mosquitoes. The female mosquito applies specific strategies for sucking blood from their animal hosts. The mosquito injects saliva at the site of piercing the host skin before drawing the blood. Mosquito saliva is the soup of a complex array of pharmacological agents that perform numerous important functions to facilitate the process of blood feeding [16]. During blood feeding, the damage caused to the host blood vessels usually results in vasoconstriction that may increase insect feeding time due to restricted blood flow to their mouth parts.
