Diagram Of The Skin: The Integumentary System
For alternate meanings see skin (disambiguation) Diagram of the layers of human skinIn zootomy and dermatology, skin is an organ of the integumentary system composed of a layer of tissues that protect underlying muscles and organs. As the interface with the surroundings, it plays the most important role in protecting against pathogens. Its other main functions are insulation and temperature regulation, sensation and vitamin D and B synthesis.

Skin has pigmentation, provided by melanocytes, which absorbs some of the potentially dangerous radiation in sunlight. It also contains DNA repair enzymes which reverse UV damage, and people who lack the genes for these enzymes suffer high rates of skin cancer. One form predominantly produced by

It consists of loose connective tissue otherwise called areolar connective tissue - collagen, elastin and reticular fibres are present. Erector muscles, attached between the hair papilla and epidermis, can contract, resulting in the hair fibre pulled upright and consequentially goose bumps. The main cell types are fibroblasts, adipocytes (fat storage) and macrophages. Sebaceous glands are exocrine glands which produce sebum, a mixture of lipids and waxy substances: lubrication, water-proofing, softening and antibactericidal actions are among the many functions of sebum. Sweat glands open up via a duct onto the skin by a …show more content…
Unless enough care is taken it will become cracked or inflamed. Unclean skin favors the development of pathogenic organisms. The constantly peeling off dead cells of the epidermis mix with the secretions of the sweat and sebaceous glands and the dust found on the skin to form a filthy layer on its surface. If not washed away the dirt and dead skin slurry begins to decompose emitting a foul smell. Functions of the skin are disturbed when it is dirty and it becomes more easily damaged. The release of antibacterial compounds decreases. Dirty skin is more prone to develop infections. Cosmetics should be used carefully because these may cause allergic reactions. Each season requires suitable clothing in order to facilitate the evaporation of the sweat. Sunlight, water and air play an important role in keeping the skin healthy.

The skin supports its own ecosystems of microorganisms, including yeasts and bacteria, which cannot be removed by any amount of cleaning. In general these organisms keep one another in check and are part of a healthy skin. When the balance is disturbed, e.g., by antibiotics which kill bacteria, there may be an overgrowth and infection by yeasts. The skin is continuous with the inner epithelial lining of the body at the orifices, each of which supports its own complement of

    The integument is made up of two parts, the skin and accessory structures. Skin or otherwise know as cutaneous membrane makes up a vast majority of the Integumentary System.

Some individuals with scars go a step further with removal of the scar tissue.…

    The bacteria can survive on skin are normally gram-positive because of their ability to survive in dry and humid conditions. The conditions on the skin are not suitable to all bacteria such as gram-negative bacteria and only those that can survive salty and dry conditions can survive. The skin has defense mechanism against pathogens such as its low moisture level, acidity, rigidity and defenses released by the skin. Certain areas of our body do contain gram-negative bacteria, staphylococcus aures and corynebacterium. Those areas are the armpit, groin and toe webbing because it is a moist area, however the bulk of human skin contains gram-positive bacteria such as staphylooccus epidermis and propionobacterium.…

    How does the integumentary system work with other systems? We already spoke about our skin as one of the first defense mechanisms in our immune system. Our skin has tiny glands that secrete sweat and oil. Those glands are termed exocrine glands and are not like the glands of our endocrine system. While it may feel a bit slimy, those fluids decrease the pH on the surface of our skin and kill microorganisms. There are even enzymes in our sweat that can digest bacteria.…

    Skin is a protective organ that covers the body and merges with the mucous membranes at the openings of the body such as the mouth and anus. It is attached loosely to underlying tissues. It also varies in thickness from 0.5mm on the eyelids to 1/7 inch or more on the palms and soles. Function of the skin is to protect the body from damaging external agents like extremes of temperature and invades organisms like viruses, bacteria, fungi, and parasites. Specialized nerve receptors in the skin allow the body to sense pain, touch, and pressure. Skin plays a role in temperature regulation, protection from ultraviolet light, in the manufacture of vitamin D and in attracting the opposite sex.…
