http://www.bbc.co.uk/science/humanbody/body/factfiles/skin/skin.shtml. Structurally the skin consists of three separate layers 1) Epidermis 2) Dermis 3) subcutaneous tissue.
Skin 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 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

(5 points) The human sense of touch is known as the somatic or somatosensory system. The skin is the biggest and most complex organ in the somatosensory system.The somatosensory system permits

Around 60 2. Barrier to UV radiation, protects against harmful organisms, prevents loss of water, regulates body temperature, is an excretory organ, and is a receptor for external stimuli
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)
guidelines for the prevention and treatment of skin tears as cited (Ontario). Skin tears are traumatic wound that have been described as the “underestimated” wound and a
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.
The skin is the body's greatest organ, and it serves as a guarding deterrent. Its wellbeing and surface appearance are controlled by common components and furthermore the limit of the parts that incorporate the layers underneath
Your skin has two layers. The outer layer is called your epidermis. It's made up of epithelial cells. The main purpose of your epidermis is to protect your body from germs and from getting injured. If we didn't have an epidermis, we'd be sick all the time, and any little cut would hurt extremely bad. On
There are several organ systems involved with performing or assisting with the action of typing. The integumentary system acts as a barrier to protect the fingers from harm or pathogenic agents from the keyboard. Thick skin, such as the skin of palms, has five skin layers including the stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, and stratum corneum, in order to protect the fingers from wear and tear. The integumentary system also provides protection with chemical barriers such as the acid mantle, which retards bacterial growth; human defensin, which kills bacteria; and cathelicidins, which prevent infections. Biological barriers in the epidermis such as Langerhans cells, tissue macrophages that act as antigen presenting cells, are also present. The integumentary system is also responsible for cutaneous sensation by sending signals received from Merkel cells in the epidermis and Meissner’s corpuscles in the dermis to the brain via nerves.
PART A - The skin is the largest organ of the body, the skin protects us from microbes and the elements, it also helps regulate body temperature, and permits the sensations of touch, heat, and cold. There are three layers of skin, this includes the epidermis, the outermost layer of skin, provides a waterproof barrier and creates our skin tone, the dermis, beneath the epidermis, contains tough connective tissue, which gives the skin flexibility and strength, hair follicles, produce the various types of hair found throughout our body, sweat glands, these produce sweat in response to stress and heat, blood vessels of the dermis are what help regulate our body temperature, and nerve ending, which sense pain, pressure and temperature and the hypodermis, the deeper internal tissue is made of fat and connective tissue, this functions as a protective shield for
“The skin is the largest, most visible, and most complicated of the body systems. In an average adult, it covers more than 3,000 square inches and weighs about six pounds. It is served by one third of all the blood circulating the body” (Saxon, 2010, p. 17).The skin has many functions in which one needs in order to stay healthy and living. The skin protects the underlying tissues and structures of one’s body, and prevents them from drying or obtaining an excessive loss of water and electrolytes. It also regulates the temperatures in the body through mechanisms such as sweating and shivering. Acting as a physical, chemical, and biological barrier, the skin protects from harmful bacteria and foreign substances contacting with the body. Most importantly,
The human skin are the most fragile organ of our body. The skin can attract many different diseases and contains three layers. In my essay I will tell and explain the many different diseases that the skin can attract and what consist of the skin. The thin layer of tissue forming
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.
