Organisms are composed of atoms that form molecules which form macromolecules (Shier, Butler, & Lewis, 2009). These molecules join and form organelles which structure cell that for tissues (p.3). Tissues form organs and the organs working together form organ system (p3). These organ systems make up the organism (p3). Each organ system has an important function in the body. These systems all work together in order to keep and support the conditions that the cells, tissues, and organs need to function properly. There is one system that is not as well known as other; it is the intergumentary system. Most people know the organs of the intergumentary system, but they do not know that these organs work together to form this system.
The intergumentary system is composed of the skin and the structures related to the skin, which include the hair, the finger nails, the sensory receptors and the glands (Shier, Butler, & Lewis, 2009). This system has an important function since it provides protection to the body, helps to maintain body temperature, and contains sensory receptors (p.117). The skin which is the largest organ in the body and an organ of the intergumentary system has essential function such as regulating homeostasis and body temperature, also delaying the loss of water from deeper tissues, storing sensory receptor, synthesizing biomechanical, and discharging waste from the body (p.117). The skin has two layers: the epidermis (outer layer) and the dermis (inner layer) (p.117).
There is also a subcutaneous layer or hypodermis (Shier, Butler, & Lewis, 2009). According to Shier, Butler, and Lewis 2009 “as its name indicates, this layer is beneath the skin and not a true layer of the skin.” This layer has the blood vessels that su...

...se glands help to balance the body temperature (p.124). The fluid that this eccrine glands secret is transported outside of the body by a tube that has an opening to the exterior as a pore (p.124). Another sweat gland is the apocrine gland which is activated at puberty. According to Shier, Butler, and Lewis 2009 “these glands secrete by the same mechanism as eccrine glands, usually when a person is emotionally upset, frightened, in pain, or during sexual arousal.” Other sweat glands are seruminous glands which secret, and the female mammary glands which secrete milk (p.124).
The nails which are another accessory of the skin cover and give protection to the end of fingers and toes (Shier, Butler, & Lewis, 2009). The nails have a lunula which is the area of growth in the nail (p.122). This means that if the lunula is damaged the nail probably will not growth again.
The integumentary system has five main functions. The five main functions of the integumentary system are protection, regulation, sensation, absorption, and secretion. It consists of the hair, nails, skin, sebaceous and sweat glands. The largest organ of the entire body is the skin. The skin consists of three different layers. The epidermis, the dermis, and the subcutaneous layer, these are the three layers of the skin. There is a layer that is deeper than the skin and contains body fat, that layer is called the hypodermis. Sweat glands are also called sudoriferous glands. One of the functions of the skin is to maintain homeostasis. Synthesis of vitamin D, excretion of urea, excretion of salts and water are a few things that the skin is also capable of. The top layer of the skin is called the epidermis. The epidermis contains five different layers. These layers are the stratum corneum, the stratum lucidum, the stratum spinosum, and the stratum basale. In the epidermis there are four different cell types. The keratinocytes which produce keratin, the merkel cells that are sensitive to touch, the langerhans cells which is a dendritic type off cell, and the melanocytes which produce melanin.

Human skin is a multi-layered structure. It is generally divided into two layers, the epidermis and the dermis. Below the dermis a subcutaneous fat layer is found. The epidermis can be further divided into several sub-layers. These are the stratum corneum, the stratum lucidum, the stratum granulosum, the stratum spinosum, and the stratum germinativum. The stratum germinativum is usually referred to as the basal layer.
It is made mostly of connective tissue (areolar and dense irregular). Connective tissue provides support to the epidermis because it consists of numerous collagen and elastin fibers. The dermis serves as a first line of protection so that pathogens (bacteria and/or microbes) that have made it through the epidermis cannot move any farther. The dermis produces a gel-like substance within the areolar connective tissue that slows down the movement of microbes. The dermis also supplies blood and nutrients to the epidermis (via blood vessels) and supports sensory reception (nerve fibers). Accessory structures found in the dermis include a portion of the hair follicle, secretory glands (sebaceous and sweat glands), touch receptors (nerve fibers) and blood vessels. There dermis has two layers: the papillary layer and reticular layer. The papillary layer is the outer top portion of the dermis that is below (deep to) the epidermis. It has a sub layer called dermal papillae. Dermal papillae has ridge-like projections that interlock with ridges in the lower portion of the epidermis (epidermal ridges). These ridge-like projections have sensory receptors and capillaries. The sensory receptors are called tactile corpuscles that detect light, delicate touch and capillaries supply blood and nutrients to the epidermis above. The reticular layer is the deeper portion of the dermis and consists mostly of dense irregular connective tissue (ground substance and randomly arranged collagen fibers). The lamellated corpusle is a large, leaflet like sensory receptor located in the reticular layer. This receptor detects pressure, rough touch and
Cutaneous membrane also know as the skin. The cutaneous membrane actually has a surface area of over 20 feet and is actually an organ, comprised of all four tissue types, epithelial, connective, muscle, and nervous. Because of this and having several accessory organs, the Cutaneous membrane is considered to be an organ system. The cutaneous membrane is comprised of three different layers, the epidermis, the dermis, and the hypodermis, each with their own purpose and characteristics.

Our skin functions as a daily defense for our bodies against disease because of skin and mucous membranes. The skin is a massive organ and it protects everything inside our bodies such as our muscles, bones and organs. Our skin protects us from bacteria, parasites, viruses and pathogens ...
Description of the tissues: The function of keratinized stratified squamous epithelium is to provide protection from foreign pathogens, protect against abrasion, and provide waterproofing of the skin. This epithelium is identified by the many layers and flat nuclei towards the apical surface. In the reticular layer there are merocrine glands secrete sweat for thermoregulation. There is a blood vessel which supplies the dermis with nutrients (the epidermis is avascular and receives nutrients through diffusion). The epithelium is attached to the
It is very important to know the guidelines of the Integumentary system because it consists of the largest organ on the human body and that is the skin. The integumentary system consists of the skin, hair, nails, and exocrine glands.To get through anything in the human body it has to go through the skin.
Organ systems like the integumentary, skeletal, nervous, and endocrine all play a big role in helping the body maintain homeostasis. The integumentary system helps maintain by giving protection, regulating body temperature, and sensory receptors. All of this plays a big role maintaining the internal conditions so the body may function. The skeletal system helps by producing red blood cells in place of the old ones that die. It also helps to maintain the calcium levels in our blood stream. The nervous system maintains homeostasis by controlling and regulating other parts of the body like letting you know when you’re tired or when you’re hungry. It makes sure the body is acting how it should by using receptors. The endocrine system releases hormones that are sent to different parts of the body that control the body’s reaction to things like stress, pain, and growth. These hormones give directions to the body for the fight or flight response so that it can adjust and maintain
The skin is part of the Integumentary system and it is considered the largest organ in the human body. Among its functions, the skin serves as a barrier, body temperature regulator, and metabolic controler. This organ is composed of many parts such as glands, nerves, different tissues, and other important factors. Each component has a specific function for which it is responsible for.
The skin is the largest complex organ of the human body, accounting for about 15% of the total adult body weight. It covers the entire body surface as a flexible shield, which It performs many vital functions, including protection against external physical, chemical, and biologic assailants, as well as prevention of ex¬cess water loss from the body and a role in thermoregulation (Charkoudian, 2003). The skin is continuous, with the mucous membranes lining the body’s surface (Kanitakis, 2001). In terms of chemical composition, the skin is made up from about 70% water, 25% proteins and 3% lipids. The reminder includes minerals, nucleic acids, glycosamines, proteoglycans and numerous other chemicals (Wagner et al., 2002).
Body organs are not all internal as is the brain or your lungs. There is an extremely important one that we wear on the outside and is the largest organ, the skin. So important that we would literally disintegrate without it. The skin acts as a waterproof, insulating barrier, guarding our bodies from nature's toughest exposures. It protects our bodies with its many antibacterial substances to keep us immune from infections, it is also a gigantic sensor full with nerves, cell layers, and glands performing together to keep the brain in touch with the exterior world. But yet, at the same instance allows our body to move freely, proving itself as an extraordinarily versatile organ in its own right.
The body works in amazing ways like a fine tuned machine. All organ systems within the body depend on one another for survival in some way or form at all times. Cherif et al., (2010) state, the body depends on the precise action of each organ to maintain physical, mental, and emotional health of a human being. Also, homeostasis, the regulatory of body temperature plays a survival role in maintaining body functions. The integumentary system (skin) is the largest, and the most important part of the body. The skin is just one of the organ systems that will be discussed (Thibodeau & Patton, 2008). The body is expected to perform specific duties at specific times the organ systems as a whole, the most important organ system the integumentary system, and homeostasis, are what enables the body to perform on demand.
The skin has 3 main function. It has to regulate body temperature, remove waste (perspiration), and protect. The skin is made up of 3 layers. The epidermis is the outer thinner layer of the skin that is made up of dead and living cells. The dermis is the thicker middle layer of the skin that contains blood vessels and nerves. Sweat glands are found in the dermis, they secrete perspiration through ducts to pores on the skin’s surface. To avoid problems like warts, boils, moles, acne, and sunburn you can wash your body daily, wear sunscreen that is 15 or higher, and check your body often...
