The Integumentary System
The Integumentary System of the human body is remarkable and exciting. It is an organ system that covers approximately 20 square feet of protection for the other organ systems of the body. Let’s take a trip through the land of integumentary, making stops along the way. We will visit the different parts of this system and become familiar with their parts and functions.
SKIN
The first stop on our trip is the skin. The skin forms a barrier of protection, and a first line of defense. Hair and nails are projections of the skin that protect it from damage. There are three layers of skin, the epidermis, dermis and the hypodermis. The epidermis is made of specialized cells with very distinct duties, like soldiers in the military. The keratinocytes which make up 90% , produce and store keratin. The

Another accessory organ of the skin, nails protect the fingers and toes and give dexterity. Nails are divided into three parts: the root, body and free edge. The root is under the surface of the skin, the body is the part you can see and the free edge is the part that extends out from the edge. The nail body rest on what is called a bed, which is a layer of dermis and epidermis. This layer has capillaries which provide support to the nail body. Keratinocytes grow out from the bed to the free edge.
GLANDS
Our last stop on the tour is the glands. There are three types of glands in the skin: sudoriferous glands, sebaceous glands and ceruminous glands. These glands perform two major purposes: to regulate body temperature through sweating and to protect the skin from bacterial and fungal infections through the production of sebum. Sebum also is a lubricant for hair follicles and the skins surface. Ceruminous glands are only located in the dermis of the ear canals were they produce cerumen. This cerumen is a waxy secretion that protects the ear canal from foreign bodies while also lubricating it.
The skin is the largest organ of the body, covering and protecting the entire surface of the body. The total surface area of the skin is around 3000sq inches depending on age, height and body size. As well as the nails, hair, sweat glands and the sebaceous glands, the skin forms the integumentary system. Besides oroviding protection to the body, the skin also helps regulate body temperature, helps your
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 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.
The skin is one of the principal barrier instruments in your insusceptible framework. Little organs in the skin discharge oils that upgrade the hindrance capacity of the skin. Safe cells live in the skin and give the primary line of protection against diseases.
Diseases of the integumentary system include any disorder involving the skin, hair or nails. Common conditions such as acne and warts, chronic conditions such as psoriasis and eczema, and more serious diseases like skin cancer, for example, leukemia. All of these diseases are just a few that exist in the integumentary system.
The Integumentary System is mainly composed skin, hair, and nails. These things are usually found outside the body and are meant to protect the body from outside factors. Usually when the body receives a cut, your Integumentary System, works with other systems like the nervous system and the immune system to heal that wound. Minor things like lacerations, abrasions, and small puncture wounds don’t bleed very much. The Integumentary System, along with other systems, help it to heal fast. When you get major injuries; it can be more difficult to repair and can sometimes lead to cell damage. Deep puncture wounds, avulsions, and burns are some very major injuries that can affect your body in a number of ways. Burns can be either partial-thickness
Skin and its derivatives make up the integumentary system which acts as a barrier between the body and the outside world. Skin has physical, mechanical, chemical, and immunologic components which allow for body temperature regulation, protection against pathogens, cutaneous sensation, and metabolic functions. When the structural integrity of skin is compromised, its functions are impaired leading to major disability or even death.
In today’s day and age Integumentary diseases are looked over as normal and not many people will discuss the topic. Integumentary diseases can be a broad spectrum of different problems with the skin of our body. The Integumentary system protects and fights off anything that may be harmful for our body. In many cases the Integumentary system begins to contract a disease known as adult acne.
Its purpose is to keep pathogens and other harmful substances out. The skin is very thin but is considered the largest organ in the body. The epidermis is another major part of the anatomy. It is the top of the skin and is 40-50 rows of dermis cells. The skin system’s basic function is to protect the body from disorders and diseases such as herpes, sunburns and cold sores. the body parts that are included in the integumentary system are hair, skin, nails and exocrine glands. It works with the other body systems by helping the digestive system absorb vitamin D and the immune system helps the integumentary system by preventing and viruses/bacterias from entering the bloodstream and harming the tissues and
Fact 1: Biology - The skin The skin is the outer most layer of most animals and is seen as the largest organ of the body consisting of 3 layers, namely the epidermis, dermis and sub-dermis or hypodermis. These layers contain different specialized structures, as can be seen on the diagram on the cover page, which perform functions that are essential for our survival. The skin separates the internal body from the surrounding environment and thus it protects the body against water loss, radiation, toxic chemicals and infections in the surrounding environment. One of the structures that is further discussed are melanocytes in the epidermis and melanin production.
The four functions of the integumentary system are temperature maintenance, protection, avails make vitamin D, sensory replication and excretion of wastes. Due to the human body being very intricate system the integumentary system is a required needed material to ascertain the body function felicitously. The integumentary work with another system such as the immune system, digestive system, circulatory system and nervous system. The skin is the first defense of the immune system of protections. The tiny glands in the skin secrete oils that enhance the barrier function of the skin. The skin, additionally fights to protect against infections by availing to synthesize and absorb vitamin D in the digestive system. When it comes to keeping your
Skin is made of stratified squamous epithelium and inner connective tissue layer. Skin is made of several layers. This layer is top of the hypodermis. All part of the body has the stratified squamous epithelium, but in each of them has a totally different thickness. Hypodermis has the all blood vessels, nervous, and fat.
Integumentary system is the largest system of the body. Made with epidermis, dermis hypodermis, hair, and nail. The integumentary system has multiple roles in homeostasis. Protection, temperature regulation, sensory reception, biochemical synthesis and absorption. Temperature sensors located all over the skin pass information about surrounding environment to hypothalamus. If body becomes too hot, the hypothalamus signals the sweat glands to release fluid to help the body cool down and when it is cold the glands close and body loses less fluids. Integumentary system protects body from external environment if it fails viruses and bacteria will be able to enter the body easily.
The integumentary system is a very important part of living. It consists of the skin and its accessory organs – hair, nails, sebaceous, or oil, glands, and the sudoriferous, or sweat, glands. Your skin alone weighs more than six pounds and covers more than three thousand square inches. The skin to me is considered customizable because you can alter it in many different ways. Many people pierce the skin on the ears, face, navel, and genitalia. They also tattoo their skin with permanent ink.
