The Skin Or Integumentary System

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.

Structurally the skin consists of three separate layers 1) Epidermis 2) Dermis 3) subcutaneous tissue.

The skin is divided into three different parts including the epidermis, dermis, and hypodermis. The epidermis is the outermost layer of the skin. This region of the skin has no blood cells or blood vessels running through it. All of the nutrients that the epidermis needs are received through diffusion from the dermis. The epidermis is made up of stratified squamous epithelial cells. The epidermis is made of five separate layers: the stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, and the stratum corneum. Starting at the innermost layer, the stratum basale is where mitosis of keratinocytes takes place. This layer of the epidermis also contains melanocytes which give the skin it’s pigment. As mitosis takes place in the stratum

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.

In the epidermis there are 4-5 layers of cell, however, the skin that is most exposed to the sun is thin skin, which has 4 layers, because thick skin is located in the palm of your hands and feet. Sunlight is mostly exposed to outer surface of skin, epidermis, which also makes sense why basal and squamous cells is the most common skin cancer. In lab, we got to look at a 3D skin model, which showed all the layers of the skin. This allowed us to see where the layers of the skin are at and also what layers and structured get effected with

There are three primary layers of the skin: the outer layer, the epidermis and the layer beneath, the dermis and the hypodermis. The epidermis is thin, tough and waterproof while protecting the body from outside bacteria invading the body. It also contains keratinocytes which are from the basal layer which is the deepest layer of the skin. The keratinocytes reach up to the epidermis, shed and new ones form again. The dermis is the second layer of the skin and is the thickest. It is made from fibrous and elastic tissues which are made from fibrillin, elastin and collagen to create the strength and flexibility. It also contains sweat and oil glands, nerve endings, blood vessels and hair follicles. Sweat glands help the body cool off during heat

The integumentary system has five very common diseases. They include, Alopecia Areata, Psoriasis, Warts, Dermatitis or Eczema, and Athlete’s Foot. Only two out of the five are contagious, but all are or can become severe if not treated immediately or properly.

In order to understand further how pressure ulcers can be form, we need to understand the structure of the skin. The system that involved are integumentary system. Integumentary system is makes up about 16 percent of our total body weight. This shows that even a healthy person can develop pressure ulcers if they are left in only one position for long time period. The integumentary system is place where inside of our body and outside world meet. It works as a barriers and known as body’s first line of defense against an often hostile environment. The integumentary system divided into 2 parts which are cutaneous membrane and accessory structures that include the hairs, nails and exocrine glands. Moreover, blood vessels and nerve fibers also support

Stratum Corneum this layer is the outer most layers; it is formed from numerous layers of compressed scale- like, overlapping cells. What makes up the surface of the skin is corneocytes, which are commonly called ‘dead skin cells’. Keratinocytes are found in the epidermis they travel up through the layer where they are formed into corneocytes. The stratum corneum layer protects against lights, chemicals, water loss, heat and bacteria.

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.

The Integumentary System plays an extremely important role in the human body. Due to the fact, it is the body’s first line of defense against

Integument, network of features that forms the covering the body,including skin, hair, nails and sweat glands. It is responsible for excreting wastes and regulating temperature, and is the location of sensory receptors for pain, pressure and temperature. Integument, in biology, network of features that forms the covering of an organism. The integument delimits the body of the organism, separating it from the environmentand protecting it from foreign matter. At the same time it gives communication with the outside, enabling an organism to live in a particular environment.Dog's epidermis has a turnover rate of 20 days compared to humans which occurs approximately every 28 days. The epidermis of a dog is 3-5 cells thick however in humans it is

The skin or integument part of a human is complex in a way that it has many parts that works together, the skin of a human is composed of layers which are the Stratum basale, lucidum, spinosum,granulosum and corneum and this layers shows that the skin is complex in a way that they have different works/function.

The skin also known as the Integumentary system is the largest organ in the human system; it covers about 20 square feet. The skin has many functions, most of it is having to act as a protection agent. The skin is an important organ because it stops unwanted things from entering the body through the pores. It protects us from microorganisms; it cushions and insult the tissue laying underneath it; it protects the skin from involuntary damages like cuts and bumps; It protects us from chemical damages like acids, alkalis and many more, protects us from thermal damages like heat. The skin acts as a first wall of defense for things on the outside by disallowing them to enter and for things on the inside by disallowing them to leak out or exposed. For example, the skin stops fluid leakage from the body and it helps keeps and maintain the basic body temperature. The skin not only protects and cushions, it also acts as an excretory system. It helps excrete some toxic substances the body doesn’t need just like the urinary system does. It does this by releasing salts, water, and urea in form of sweat through the pores of the skin.
