...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...

...Seeing how the human body functions is something that intrigues many people. The body is made up of many different systems. “These systems include the integumentary system, skeletal system, muscular system, lymphatic system, respiratory system, digestive system, nervous system, endocrine system, cardiovascular system, urinary system, and reproductive systems.” (Lutz, 2013) All of these systems are used to make the body function properly, but the main systems that are well known are the skeletal system, muscular system, and the cardiovascular system. The skeletal system is primarily about bones and cartilage. This system is the foundation of the human body. Without it, we wouldn’t be able to stand or move. We’d be blobs. The muscular system...

...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-...

...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...

...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....

...homeostatic balance? Each organ system helps in some way to maintain homeostasis. However, the organ systems also work together to maintain a constant internal environment. There are seven organ systems (Integumentary, Musculoskeletal, Endocrine, Cardiovascular, Lymphatic, Respiratory, and Nervous) within the body. (McGraw-Hill) I will specifically be focusing on the structure of the integumentary system, and how it contributes to maintaining homeostasis. The skin is the largest organ in the body (12 to 15% of total body weight). (McGraw-Hill) There are three layers to the skin; epidermis, dermis, and hypodermis. The dermis is a connective tissue layer that lies beneath the epidermis. The dermis contains nerve endings, sensory receptors, capillaries, and elastic fibers. (McGraw-Hill) Skin isn’t the only appendage of the integumentary system; hair, follicles, nails, and glands are as well. Hair follicles are lined with cells that synthesize the proteins that produce hair. Sebaceous glands secrete the oily substance on hair. If a sebaceous gland becomes clogged and infected, it becomes a pimple (homeostatic imbalance). (Marieb) There are two types of sweat glands associated with the integumentary system; eccrine (all over the body), and aprocrine (smelly sweat). Nails consist of highly keratinized epidermal cells. The nails arise from the nail bed. What does the integumentary system do to help with in maintaining homeostasis? The integumentary system has multiple roles in homeostasis...

...FUNCTIONS OF THE INTEGUMENTARY SYSTEM The integumentary system has many functions, most of which are involved in protecting you and regulating your body’s internal functions in a variety of ways: · Protects the body's internal living tissues and organs · Protects against invasion by infectious organisms · Protects the body from dehydration · Protects the body against abrupt changes in temperature · Helps dispose of waste materials · Acts as a receptor for touch, pressure, pain, heat, and cold · Stores water and fat Skin structure The skin is the largest organ of the body. It has three main layers, the epidermis, the dermis and the subcutaneous layer. The epidermis is an elastic layer on the outside that is continually being regenerated. It includes the following: Keratinocytes - the main cells of the epidermis formed by cell division at its base. New cells continually move towards the surface. As they move they gradually die and become flattened. Corneocytes - the flattened dead keratinocytes that together make up the very outer layer of the epidermis is called the stratum corneum or horny layer. This protective layer is continually worn away or shed. Melanocytes – produce the pigment melanin that protects against UV radiation and gives skin its colour. The dermis is the inner layer that includes the following: Sweat glands – produce sweat that travels via sweat ducts to openings in the epidermis called pores. They play a role in temperature regulation...
