Skin and the Integumentary System A. Skin is composed of 2 main layers 1. Epidermis is made of keratinized stratified squamous epithelial tissue, is superficial to the dermis, and is avascular. 2. Dermis is mainly connective tissue, is deep to the epidermis, and is vascular * The skin contains collagen (for strength) and elastic (for stretch) fibers.
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.
HSC 3051 UNDERTAKE TISSUE VIABILITY RISK ASSESNENTS Understand the need for tissue viability risk assessment Describe the anatomy and physiology of healthy skin http://bp3.blogger.com/_e-mPA_6ZQyg/R5osT7sMM1I/AAAAAAAAGIo/xq-t_lNiMGk/s400/Skin.jpg Skin is the largest organ in the body and accounts for about 15% of the body’s weight. The chemical composition, of skin is about 70% water, 25% protein and 2% lipids. The remainder includes trace minerals, nucleic acids, glycosaminoglycans, proteoglycans and numerous other chemicals. The skin consists of three main layers: The Epidermis: This is the outer layer of skin, and has a thickness between.05 mm (eyelids) and1.5 mm (palms and soles) It is made up of 5 layers. They are from bottom to top: stratum basale stratum spinosum stratum granulosum stratum licidum stratum corneum Cells in the stratum basale are shaped like columns.
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.
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.
P2 Outline the Main Tissues Of The Body Epithelial Epithelial tissue is basically the linings of both the internal and external surfaces of the body and can be divided into two groups. The groups depend upon the number of layers of which it is composed. These two groups are simple epithelial and compound. Simple squamous are thin, flat plates and their main function is osmosis (which is the passage of water molecules from a region of low concentration to one of high concentration through a semi-permeable membrane) and diffusion (which is the passage of molecules from a high concentration to a low concentration). They form the lining of cavities such as the mouth, blood capillaries, heart and lung alveoli and make up the outer layers of the skin.
Unit 4222-229 Undertake agreed pressure area care (HSC2024) Karen Yardley Outcome 1 understand the anatomy and physiology of the skin in relation to pressure area care 1.1 describe 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, 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.
Make sure that you use colour and make the poster clear, attractive and interesting. P2 Outline the structure of the main tissues of the body Produce a written assignment that shows an understanding of the main tissue types and the roles they play in two named organs. Two organs you could choose might be the stomach and the skin. Here are examples of tissues types that occur in these two organs: 1. The stomach has three layers of non-striated muscle in its wall and an inner lining of columnar epithelium with goblet cells.
The lymph vessels collect fluid, called lymph from the body tissues and return it to the blood, maintaining the fluid balance within the body. Lymph filters through the lymph nodes, which are packed with white blood cells known as lymphocytes. These are produced in the bone marrow, spleen and thymus, and they help to protect the body against infections. Spleen: This is the largest lymphatic organ. It is located on the left side of the body just above the kidney.
Identifying skin changes and limb swelling The skin is often referred to as the largest body organ and serves as the main protective barrier to prevent damage to internal tissues from trauma, ultraviolet light, temperature variations, toxins and bacteria. Each component of the skin has a role to play in protecting the body. The skin consists of two main layers, the epidermis or outer layer and the dermis which lies beneath the epidermis. Collagen and elastin are major components of the skin; they help to give support, strength and elasticity to the skin. As we age individual components within the skin decline in a variety of ways and the skin is less able to function normally.
