The integumentary system is part of an organ system which protects the body from all external processes while still being able to be surrounded by the climate change on a day to day basis. The integumentary systems most important organ is the skin, which protects the body from external damage. Not only does the system consist of skin as its main organ but also has accessory organs as well, such as hair, nails, and exocrine glands. The hairs on our bodies gives the body insulation otherwise known as heat. The nails on our fingers and toes are made from keratin and give the nail a hard covering to protect our fingers and toes from damage. Exocrine glands are important because it is how the body lets us sweat. Glands secrete products that the

The main function of the epidermis is protection but does other things as well, such as absorption of nutrients and a thing or two with homeostasis. The epidermis is made up of mainly epithelial cells but also contains four other cells and covers the outside of the body or otherwise known as the body surface. The other four cells are Keratinocytes are a fibrous protein which protects the epidermis, Melanocytes produces a brown pigment and protects the skin from UV light, Langerhans cells deals with immune response, and Merkel cells gives us the sense of touch. There are also five sublayers that are associated with the epidermis. The stratum corneum is the outmost layer contain many layers of dead keratinocytes which continually shed and replace to form new healthy cells (Rapid Learning). The stratum lucidum is just below the stratum corneum and made between 3-5 layers of dead keratinocytes (Rapid Learning). The stratum lucidum is the only layer that can be found in fingerprints, palms, and the soles of feet. Just below the stratum lucidum is where you will find the stratum granulosum which is 3-5 layers of keratinocytes and this is also where keratin will be produced (Rapid Learning). Since this layer is the site of …show more content…
The skin always has a plan of attack on what is going to happen next when there is a scratch or an open wound on the epidermis or broken through the dermis. The body does not like to be open to the outside world because that is a way for bacteria to get in the scratch or wound and causes bacteria. Having stronger skin can promote wound healing with faster healing. The first plan of action to stop the bleeding from the affected area is to form a blood clot and stop the bleeding. The clot acts a temporary shield to prevent pathogens and bacteria. The part of the skin that was damaged might swollen or inflamed because this is part of the healing process. White blood cells rush to the damaged area and fight pathogens and bacteria that have entered and get rid of them. Collagen fibers come into save the day and bring the dermis and the epidermis back together and within a few days the damaged area is new and healthy. There might be a scar after but that is all part of the healing process. When there is a scratch or wound all the components of skin work together to help repair the skin as fast as it can because the skin is a protective covering for the rest of the body. All the functions of the integumentary system work just as hard to make sure everything is in track to repair the skin. Homeostasis works with the skin to ensure that all parts of the body are working with the
