The integumentary system is an organ system consisting of the skin, hair, nails, and exocrine gland. The skin functions are to protect and cover the organs. There are three layers of the skin: epidermis, dermis, and hypodermis. The epidermis is the outer layer of the skin; it covers the entire body. The dermis is the deepest layer of skin mainly made of the dense irregular connective tissue and the nervous tissue. The lowest level is hypodermis, this is what connects the skin the muscles. Although skin serves as a protective agent it could also get infected. There are many diseases, but one common disease is dermatitis. Dermatitis is an inflammation of the skin. Eczema is considered as in inflammation of the skin.
There are different types
The Integumentary is a vast organ system composed of exocrine glands, hair, nails, and the most commonly known organ, the skin. As a large system, it can be susceptible to many different types of diseases, one of these diseases are called Psoriasis. This affects a large portion of the Integumentary system, the skin. Psoriasis are considered to be a widespread, common and recurring disease that can be chronic at times. Psoriasis are defined by its appearance of light silver in color, flaky, rash on many parts of the Epidermis.
The integumentary system can be broken down into three main categories the Epidermis, Dermis, and Subcutaneous layer each of which contain certain specialized skin derivatives including hair, nails, and several kinds of glands.

The Integumentary system is defined as “an organ system consisting in the skin, hair, nails, and exocrine glands” (Integumentary System, 1999). This systems main purpose is to protect the body from the environment around it. The skin covers and protects tissues, nerves, veins, and muscles of the body. The hair and nails give extra strength in reinforcing the skin while keeping the body warm and protecting the skin from harmful UV rays. The exocrine glands of the skin include the sudoriferous glands, sebaceous glands, and the ceruminous glands. Each exocrine gland has a different function as well as location in the skin. The following text will explain the effects of melanoma on the integumentary system.
The integumentary system also known as skin; surrounds the entire human body therefore being the largest organ. The skin and its annexes like hair, sweat glands, sebaceous glands, nails, etc. The main functions of the integumentary system is to function as a protective barrier, that keeps our body free from intrusion of foreign materials, microorganisms and prevents dehydration as well as protecting from desiccation and there are other functions also helps in elimination of waste products and in the regulation of our body tempeture. There are many other functions of the integumentary system and each organ involved in this system has its own particular use
Like we learned in chapter 1 the job of the integumentary system is to cover and protect the body but what happens if your skin develops a disease like eczema? Eczema is a chronic, common, non-infective inflammatory condition characterized by intense pruritus, redness, and scaling (Eczema, p.1). This condition can appear at any age, but it usually occurs during infancy or early childhood (Eczema, p.1). Eczema or any skin disease are the most common group of occupational health problems leading to absence from work (Eczema, p.1). Several factors play a big role in eczema, both internally and externally, depending on your genetic makeup you may be prone to getting eczema in as early as a few months after you were born or by allergens as a young
The three layers that make up healthy skin: Epidermis, Dermis and Hypodermis. Epidermis is composed of keratinized, stratified squamous epithelium. This layer provides a thick, water proof protective covering over the underlying skins. The dermis layer is composed of primarily of dense, irregular, fibrous connective tissue that is rich in collagen and elastin. The dermis contains blood vessels, nerve ending, and epidermally derived cutaneous oranges such as sweat glands, sebaceous glands and hair follicles. The last layer is Hypodermis this layer is composed primarily of loose dead skin. The fat layer provides cushioning and insulation for
Integumentary systems of humans include the skin, nails, and hair. They act as the barrier between the body’s internal and external environments. A pig’s integumentary system is also the same as a humans’. The crayfish’s integumentary system consists of its outer shell and its gills. The shell keeps things out of its body and the gills allow them to breathe. An earthworm’s integumentary system controls many of the worm’s life processes. Its body absorbs oxygen from its surroundings and allows it to diffuse into the blood through the layered skin. The skin also activates sensitivity to light, touch, and other chemicals in its environment.
Skin is the largest organ on the body. It has two layers: the thin outer layer is made up of dead skin cells that are constantly shed and replaced by new cells. The thick inner layer is made up of blood vessels, nerves, and hair follicles, which contain glands. The glands in the hair follicles produce an oily substance called sebum, which keeps the skin and hair from drying out. Daily washing will keep the skin on the face and other areas of the body clean by removing the dirt, oil, and dead cells before they can accumulate.
The skin is the largest organ of the body and it acts as a waterproof protector for all of the internal organs, it is comprised of several layers including the Epidermis which is the outer layer and is a protective multi-layered self renewing structure which varies in thickness depending on which part of the body it covers. Under this is 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 layer separates the skin from the underlying bone and muscle with a rich blood supply it also serves as an insulator and energy store. Pressure ulcers develop
The outermost layer of the epidermis is known as the stratum corneum, it is water resistant and when not damaged, it protects the body from foreign substances such as bacteria, virus etc. it also ensures the protection of muscles, blood vessels, nerves and internal organs. The skin is also thicker in regions that requires more protection such as the sole of the feet and palms.
The Integumentary System, also known as the skin, is the largest organ of the body. Its complete structure is composed of many different tissues. The skin protects the cow’s body from any bacterial invasions and physical damage. When a cow becomes sick, the skin is the first system that is affected. The integumentary system is composed of three layers: (i) Epidermis, (ii) Dermis, and (iii) Hypodermis or Subcutis. To start with the inner most layer you have the Hypodermis (Subcutis). The Hypodermis consists of connective tissues, elastic fibers and fat. When fat forms a layer of thickness it is called Peniculus Adiposus. Any reserved energy is also stored within the Hypodermis. Then you have the layer, Dermis. The Dermis supports the outer most layer, Epidermis. Dermis consist of collagen, reticular and elastic fibers which plays a large role in the strength and elasticity in the skin; as well as the maintenance and repair of the skin. Lastly, you have the Epidermis. The Epidermis alone consist of four sublayers, (i) Stratum Corneum – outermost horny layer, (ii) Stratum Lucidum – clear layer, (iii) Stratum Granulosum – granular layer, and (iv) Stratum Spinosum – prickly cell layer. The Epidermis is derived from basal membrane Stratum Basale, which presents the openings for the hair follicles. Some of the functions of the skin include: preservation of the cow’s shape, protection from water loss, protection from any physical, chemical and microbial injury imposed by an external agent. An important role of the skin is it balances its Thermoregulation, which is its ability of an organism to regulate its body
Have you ever realised how amazing our skin is? It's waterproof, stretchy, very durable and keeps our whole body in one piece. It's also the largest organ in our body. Can you imagine if we didn't have any skin? All of our organs would just fall all over the place. Your hair, nails, skin, sweat glands, and oil glands are all part of the integumentary system. By definition, your integumentary system is a complex group of tissues working together to ensure your survival.
The Integumentary system is where the initial symptoms of Scleroderma will appear. At the beginning stages, the skin will begin to harden and thicken primarily on the fingers but eventually hands, feet, face, and other skin areas on the body. Fingers typically swell and tighten resulting in restricted finger motion. Over time, the tightness of the skin will become more severe so that every day movements such as opening mouth, chewing food, and bending fingers may be lost. In some cases, the places where skin has hardened and thickened will lose the ability to sweat and grow hair.
What is homeostasis? Homeostasis is the ability or tendency of an organism or cell to maintain internal equilibrium by adjusting its physiological processes. (McGraw-Hill) How does the body maintain 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)
