The Epidermis: The Intergumentary System

The outer most layer of the skin or Epidermis contains stratified squamous, keratinized, epithelial tissue; which lacks blood vessels, and the cells are packed closely together (Sloane, 1994, p.85)

Organ system is a group of organs that work together to perform a certain task.  Humans

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 body has different organs that work together and they make up a system such as the

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

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

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 melanocytes synthesize melanin (dark brown/reddish pigment). They are in the deepest layer of the epidermis, the stratum basale. The melanocytes are located on the superficial part of the nucleus of the keratinocytes. The help protect the keratinocytes and the rest of the cells by shielding and absorbing the UV radiation, forming the color. For those who have darker skin there is more melanin produced from these melanocytes. The melanosomes (granules) which are transported along the actin filaments is where the melanin accumulates.

The skin is one of the most important organs of the whole human body. It is the largest organ in the human body and contains various functions including protecting the body from injury and preventing fluids from leaving or entering the body (Boer et al. 2016). In animals, the skin has various functions as well. The skin aids with locomotion in bats and aquatic mammals, help camouflage the body in chameleons, helps with finding mates for deer with their white tail, and serves for many other purposes. The skin is composed of three layers in the human body: the epidermis, dermis, and subcutaneous layer. Melanin is produced from melanocytes in the epidermis of the skin. Melanin is important for protection from ultra-violet (UV) rays.

Our body has levels that build up on each other, we have cells that make up tissues, and tissues that makeup organs, and organs that can make up organ system. Each cell type for the function has its own way of functioning in the body, but they all work together to release the necessary fluids the body needs and perform their function.

EPIDERMIS is the External layer of skin that demonstrations as an obstruction between the body and the earth. Stratum corneum, highest layer, is made up of corneocytes (level, dead skin cells) shaping skin's hindrance. Basal layer, lowest part layer, is the place color is delivered.

When this happens water seeps into your epithelial cells, causing them to swell up, and your skins gets red and puffy. Do you know how some people have dark skin, and some have white skin? It's from the pigments in your epithelial cells. The two main pigments that affect the color of our skin are melanin and carotene. There are two types of melanin. Most people have dark brown melanin, which gives your skin a brown, olive, or black color, but some people have red-orange melanin and they usually have red hair, and a lot of freckles. Melanin is produced by cells deep in your epidermis called melanocytes. All of us have the same amount of melanocytes, but the color of our skin is determined by how much melanin your melanocytes make, which is controlled by your DNA. When you're in the sun for awhile, your body starts generating more melanin, and can sometimes result in a freckle. A freckle is

The skin is part of the integumentary system, and it is the largest organ in the body (Human Anatomy Book, 119). The integument is made up of two layers: the epidermis and the dermis; deep to the dermis, however, is the hypodermis. The hypodermis is not part of the integument, but it is still taken into consideration as the deepest layer of the skin (Human Anatomy Book, 119). The epidermis, being the most superficial part of the skin, consists of five different layers: stratum basale, stratum spinosum, stratum granulosum, stratum lucidum (in thick skin only), and stratum corneum. The stratum basale, however, consists of many cells, one of them being melanocytes (Human Anatomy Book, 121). These cells are responsible for the production of melanin,

Stratum Spinosum is formed from two to six rows of stretched cells; they have spiky spines that attach to nearby cells. In this layer there are two other key cells Langerhans cells and melanocyte cells. Langerhans capture and process any foreign bodies, they are then distributed to the lymph vessels followed by white blood cells, resulting the immune system activating. Melanocyte cells create melanin produces skin pigment to our skin, by ultraviolent rays. The primary function is to give protection
