NCBI Bookshelf. It is made up of three layers, the epidermis, dermis, and the hypodermis, all three of which vary significantly in their anatomy and function. It also regulates temperature and the amount of water released into the environment.
Nurses need to understand the skin and its functions to identify and manage skin problems. This article comes with a self-assessment enabling you to test your knowledge after reading it. Nurses observe the skin of their patients daily and it is important they understand the skin so they can recognise problems when they arise.
The skin has many functions, including serving as an enclosing barrier and providing environmental protection, regulating temperature, producing pigment and vitamin D, and sensory perception. Anatomically, the skin consists of the following structures: epidermis, basement membrane zone, dermis, appendageal system, and subcutaneous muscles and fat. The epidermis is composed of multiple layers of cells consisting of keratinocytes, melanocytes, Langerhans cells, and Merkel cells. Keratinocytes function to produce a protective barrier. They are produced from columnar basal cells attached to a basement membrane. The rate of cell mitosis and subsequent keratinization are controlled by a variety of factors, including nutrition, hormones, tissue factors, immune cells in the skin, and genetics.

Ahmed Raza. Have you ever wondered how your food is digested, or how you can breathe, or even move your arms? If you think about it, it's pretty amazing that the human body can do all of these things and more. These actions are made possible by what is called organ systems which are collections of organs, body parts, and tissues that work together for a common goal. For example, each one of your bones is part of the skeletal system; they work collectively to provide support and movement so that you can walk and run. Your bones also work together to protect your important internal organs, such as the heart, lungs, and brain.
Human body , the physical substance of the human organism, composed of living cells and extracellular materials and organized into tissues , organs , and systems. Human anatomy and physiology are treated in many different articles. For detailed discussions of specific tissues, organs, and systems, see human blood ; cardiovascular system ; digestive system, human ; endocrine system, human ; renal system ; skin ; human muscle system ; nervous system ; reproductive system, human ; respiration, human ; sensory reception, human ; skeletal system, human. For a description of how the body develops, from conception through old age , see aging ; growth ; prenatal development ; human development. For information on the structure and function of the cells that constitute the body, see cell. For example, see abdominal cavity ; adrenal gland ; aorta ; bone ; brain ; ear ; eye ; heart ; kidney ; large intestine ; lung ; nose ; ovary ; pancreas ; pituitary gland ; small intestine ; spinal cord ; spleen ; stomach ; testis ; thymus ; thyroid gland ; tooth ; uterus ; vertebral column.
Although you may not typically think of the skin as an organ, it is in fact made of tissues that work together as a single structure to perform unique and critical functions. The skin and its accessory structures make up the integumentary system , which provides the body with overall protection. The skin is made of multiple layers of cells and tissues, which are held to underlying structures by connective tissue Figure 4. The deeper layer of skin is well vascularized has numerous blood vessels. It also has numerous sensory, and autonomic and sympathetic nerve fibers ensuring communication to and from the brain.
What do you think when you look at your skin in the mirror? Do you think about covering it with makeup, adding a tattoo, or maybe a body piercing? The integumentary system refers to the skin and its accessory structures, and it is responsible for much more than simply lending to your outward appearance.
