...The Integumentary System (skin) covers the whole body. It is water proof and is used for a mechanical barrier. The skin has many facets and functions. Therefore the functions are protection, temperature maintenance, and storage of nutrients, sensory receptors, excretion, and secretion. This entails the 3 main layers that are epidermis, dermis, and hypodermis or subcutaneous (superficial fascia) to regulate all functions inside the human body. There are a few ways the functions and facets turn the abnormal conditions to normal conditions in the human body by maintaining homeostasis. The facets use the best in beauty; which includes the hair and nails. The other name for nails is the accessory structures of the skin. Therefore it is what makes...

...The integumentary system is similar to an organ system that deals with the hair, skin, nails and exocrine glands. The main part of the integumentary system is the skin. Believe it or not, the skin is the thickest layer on your body. The other parts of this particular system such as hair and nails are found in the epidermis, dermis and subcutaneous. The integumentary system is all about protection.” (Rader) The integumentary system prevents your body from diseases such as acne, eczema and skin cancer. It provides a barrier to block different viruses and bacteria. Some risk may include becoming dehydrated and your body becoming over heated. Another risk is that the skin may experience harmful ultraviolet radiation and un-guard the skin against...

...Integumentary System The integumentary system is made up of the skin, hair, and nails. This system protects the body from the outside world by acting like a barrier. This system also retains body fluids, protects against disease, eliminates waste products, and regulates body temperature. Skin The skin is one of our largest organs. The layers of skin are capable of healing themselves no matter how many tears and rips it gets. The skin has sensory receptors that monitor the external environment and it has mechanisms that can get rid of body waste. The skin is composed of two layers; the epidermis and the dermis. Epidermis The epidermis the outer layer of the skin and it is made up of many layers of flattened epithelial cells. The top layer...

...VENUS THE INTEGUMENTARY SYSTEM The skin is the largest organ in the body: 12-15% of body weight, with a surface area of 1-2 meters. Skin is continuous with, but structurally distinct from mucous membranes that line the mouth, anus, urethra, and vagina. Two distinct layers occur in the skin: the dermis and epidermis. The basic cell type of the epidermis is the keratinocyte, which contain keratin, a fibrous protein. Basal cells are the innermost layer of the epidermis. Melanocytes produce the pigment melanin, and are also in the inner layer of the epidermis. The dermis is a connective tissue layer under the epidermis, and contains nerve endings, sensory receptors, capillaries, and elastic fibers. The integumentary system has multiple roles in homeostasis, including protection, temperature regulation, sensory reception, biochemical synthesis, and absorption. All body systems work in an interconnected manner to maintain the internal conditions essential to the function of the body. Follicles and Glands Hair follicles are lined with cells that synthesize the proteins that form hair. A sebaceous gland (that secretes the oily coating of the hair shaft), capillary bed, nerve ending, and small muscle are associated with each hair follicle. If the sebaceous glands becomes plugged and infected, it becomes a skin blemish (or pimple). The sweat glands open to the surface through the skin pores. Eccrine glands are a type of sweat gland linked to the sympathetic nervous system; they occur...

...The integumentary system is comprised of cutaneous membrane and accessory structures. Accounting for approximately 16% of the body's total mass, it is the largest and most accessible organ that is constantly providing protection from external elements such as microorganisms, UV and chemical exposure (Martini, Nath & Bartholomew, 2012). The appearance of the skin is due to interdependent biological and physiological factor that are all subject to changes from intrinsic and extrinsic elements of ageing (Draelos & Pugliese, 2011). This essay will address the function and structure of the skin and how they changes with age. The epidermis consists of stratified layers where the majority of cells are keratinocytes which manufacture the protein keratin....

...THE ITEGUMENTARY SYSTEM The system is composed of the following: Skin, hair, nails and glands (sebaceous glands, sweat/sudoriferous glands, ceruminous glands). The following is its functions (SYSTEM) 1. Protects the body from the body by acting as barriers to microorganisms, water and excessive sunlight. 2. Protects it against dehydration (dessication) and water absorption. 3. Regulates body temperature through heat loss from dilated vessels, evaporation from perspiration, and retention from restricted vessels. 4. Serves for cutaneuos sensation by its sensory receptors that respond to heat, cold, pressure, touch, vibration and pain. 5. Performs metabolic functions as I he synthesis of melanin keratin, and vitamin D. 6. Contains organs like the sweat glands responsible for the excretion of nitrogenous wastes. 7. Acts as blood reservoir. SKIN: DESCRIPTION AND LAYERS: It is the largest skin of the body in terms of surface area that is about (2 sq. meter/2.2 sq. ft. Also the heaviest which weigh about 4-4.5kg/10-11 lbs. which is almost 7% of the total body weight. The following are its layers: EPIDERMIS: This the outer protective layer of the skin. The thickness is about 30-50 cell layers. Also called as the surface skin. There are our types of cells found in the epidermis namely: • Keratinocytes- produces keratin – waterproof materials • Melancocytes- produces melanin for pigmentation • Langerhans cells- macrophages- garbage patrol • Merkel cells-...

...The Integumentary system is the body’s largest organ. In the Integumentary system you have skin, hair, nails, glands and nerve receptors. The function of the Integumentary is to cover and protect the body. It protects the body from changes in temperature, also acts as a receptor. Your skin is very important it is the thickest part of the body. It Important that your skin is functioning, so that is protects the rest of the body as It’s supposed to. “Melanoma: Causes, symptoms and treatments” Melanoma is not the most common disease. It is known to be the most dangerous because it can maneuver around the skin cells. Being over exposed to the sun or radiation without protection could play a large roll of melanoma. Melanin is the pigment that gives color to the skin, hair and eyes. Melanomas are usually black or brown. It can also be other colors such as pink, red, purple, blue or white....

...any pain because of nerve damage. They cause the most damage, extending through every layer of skin. Depending on the cause, the most common symptoms for third-degree burns can include; waxy and white color, char, dark brown color, raised and leathery texture, blisters that do not develop. When talking about healing the first degree are very minor and heal very quickly. But second and third-degree burns have a more complex way of healing. The healing process for these burns have four stages; hemostasis, inflammation, proliferation and maturation. Although the stages of wound healing are linear, wounds can progress backward or forward depending on their internal and external patient conditions. In conclusion, I enjoyed reading the integumentary system. It is amazing how the body works and how it can repair itself. Even though it might take some out-side intervention it is amazing watching the human body take care of itself....

...The skin is the largest organ the human body has, covering around 22 square feet of skin and weighing an average of 6.6 pounds. It contains 3 different layers which involve the dermis, the epidermis, and the subcutaneous tissue. The skin performs multiple functions such as being a barrier from bacteria and virus’ entering your body and allowing you to sense the world. It also acts as the receiver of the harmful UV radiation to prevent your body from receiving it. This at times causes a dangerous build-up of UV radiation hitting the dermis of the skin and resulting in the skin cancer known as melanoma (Owens 2014). Also known as malignant melanoma, melanoma is the most dangerous form of skin cancer that occurs when DNA damage to the skin causes skin cells to multiply rapidly and form malignant tumors on the skin. Melanoma tumors are mostly brown or black and if unseen and untreated early may spread to the rest of the body and cause fatal ends. According to the American Cancer Association, there are over one hundred and thirty five thousand cases of melanoma being diagnosed a year in the United States. (Swetter 2014) Melanoma can also arise from pre-existing melanocytes present in moles and warts. The melanocytes can mutate and give rise to the melanocyte skin cancer. Melanoma cases are still being reported up to 2014 with over 76,100 new cases being reported and near 10,000 deaths and counting as shown by the research of David Holmes (2014). Melanoma begins at the very top...

...1.1The skin is a live and always developing organ that contains many special cells and structures. The skins' function is to act as a protective barrier that can sometimes encounter hostile environments. The skin is also vital maintaining the proper body temperature in order to function well. It is very complex as it gathers sensory information from the environment, and plays an important role in the immune system protecting us from disease. There is a 3 layer structure of the skin; the epidermis, dermis and subcutaneous tissue. Pressure sores can happen because of reduced mobility, for example being in the same position whether it be in a chair or bed; the skin is not exposed to enough air and bodily fluids can build up, causing a sore from...

...Introduction, Organization & Integumentary System Trident University Introduction: The integumentary system, otherwise known as, the skin is the largest and one of the most important organs in the human body and is made up of three different layers, the epidermis, the dermis and the sub-cutaneous. It is the organ system that is constantly changing and regenerating itself over a period of four to six weeks as it protects our internal body parts from damage. It also performs necessary functions like, temperature regulation, waste excretion and it is the protective coating over the internal body tissues. The skin also serves as the sensory receptor for pain and pleasurable sensations from pressure and temperature and, when we are exposed to sunlight, our integumentary system also generates necessary vitamin D. (Sanders, 2007) The integumentary system makes up around seven percent of a human being’s total body weight and is composed of the skin, skin derivatives, glands, hair and nails. (Graaff, 2001 ) How Skin cells are formed: The human skin is composed of several layers. The surface layer, or the one you can see, is the epidermis. The epidermis is composed of multiple layers of cells made up of Keratinocytes and they comprise roughly 85 percent of the cells in the epidermis. These cells make keratin, a hard protein substance which provides structural integrity and also makes up your nails and hair. New keratinocytes are grown at the lowest level of the epidermis...
