The Integumentary System happens to be one of the most fascinating systems of the body which contains the largest organ,the skin itself. Three layers make up the skin which are the epidermis (epi meaning upon or above) the outermost layer, the dermis which is the middle layer and lastly, the subcutaneous or the hypodermis (hypo meaning below). Several items that make up the system are hair,nails,and our glands. Our hair helps with the regulation of body temperature. Our nails help protect the end of the fingers and toes because if they weren 't present there would be exposed skin. Lastly, we have the glands which are the sudoriferous (eecrine and apocrine) or the sweat glands and sebaceous or the oil glands. The glands help with the protection and the regulation of body temperature in the Integumentary System, which truly when you
One you may not think of or pay too much attention to is the Integumentary System, especially on how everything is formed or grown within it. Skin, hair, nails and the sweat and oil glands are accessories of this system. When laid out the skin is the largest organ that makes up the outer shell of the human body. The Integumentary system is always growing and making new cells and tissue. The skin itself is made up of several layers and is important for several reasons. Some functions of the skin are the protection from bacteria and not letting anything harmful into the skin or body, regulation of body temperature, production of vitamin D which is needed to maintain the absorption or making of calcium. Sensations,which is the sense of touch, like when someone softly brushes up against your cheek or arm. Our hair helps with this also,the excretion of waste products from the body are excreted out through sweat. Epidermis, dermis and the hypodermis or subcutaneous layers are all the working staples of these functions in this
To begin we will look at the integumentary system and its entire multitude of functions. The main components of the integumentary system are the skin, hair, nails, glands and nerves. For the purpose of this paper we will focus mainly on the levels of the skin and their functions. While the integumentary
The nail is a complex cutaneous structure that consists mainly of the nail matrix, nail plate, nail bed, cuticle (eponychium), and nail folds. The cuticle is an outgrowth of the proximal fold, which is situated between the skin of the digit and the nail plate, providing a waterproof seal from external irritants and pathogens.
Hair is considered one of the components of the integumentary system, along with the skin, nails, glands and nerves. Mammalian hair has many functions including protection from environmental factors and the ability to disperse sweat gland products such as pheromones. Almost every part of the human body is covered by hair except for the palms, hands and bottoms of the feet. On average, every person has about five million hairs; each of these hairs is born from a follicle or tiny tube-like structure that grows into the dermis layer of the skin. Oftentimes this follicle even reaches the subcutaneous layer, which is made of fat and connective tissue. (UXL Complete Health Research, 2001)
Regulation- Blood vessels help maintain a stable body temperature by controlling the blood flow to the surface of the skin (Terfera, David, and Jegtvi)
The model of addiction etiology that best describes why people get addicted and how best to help them is biopsychosocial model. The biopsychosocial model, first developed by cardiologist Dr. George Engel, is today widely accepted by the mental health professions. The biopsychosocial model describes addiction as a brain illness that causes personality and social problems. The biopsychosocial model lets us to make solid and accurate differences between substance use, abuse, and dependence. It also allows the signs of addiction to be recognized and structured into progressive stages.
The skin is the largest organ in the body, covering the bones and internal organs, protecting them from injuries, it serves as a barrier to germs, and bacteria and helps to prevent fluid loss. The skin helps to control the body’s temperature and also aids in removing certain body wastes, therefore making it a vital organ just as any other organ such as the heart or brain.
In the world of cinema, there’s almost always a discussion regarding what scenes would be suitable for the grasping imagination of any audience, young or old. Alfred Hitchcock’s 1960 film, Psycho, sparked a plug for the movie industry as it was the first movie of its kind to display such graphic scenes of sex and violence to a worldwide audience.
The second layer of the skin is called the dermis and is also known as the middle layer. The dermis is what holds the body together. The dermis has layers to it as well as the epidermis. There are two layers to the dermis, the papillary layer and the reticular layer. The cells of the dermis are fibroblast, macrophages, mast cells, and scattered white blood cells (wbc’s). the dermis is richly supplied with nerve fibers and BV;s. dermal BV’s is also a part of the integumentary system, dermal BV,s have converging and diverging vessels that ar...
The integumentary system is composed of the skin and the structures related to the skin, which include the hair, the finger nails, the sensory receptors and the glands (Shier, Butler, & Lewis, 2009). This system has an important function since it provides protection to the body, helps to maintain body temperature, and contains sensory receptors (p.117). The skin has essential function such as regulating homeostasis and body temperature, also delaying the loss of water from deeper tissues, storing sensory receptor, synthesizing biomechanical, and discharging waste from the body (p.117). The skin has two layers: the epidermis (outer layer) and the dermis (inner layer) (p.117). There is also a subcutaneous layer or hypodermis (p.117). According to Shier, Butler, and Lewis 2009 “as its name indicates, this layer is beneath the skin and not a true layer of the skin” (p.117). This layer has the blood vessels that supply the skin (p.117).
The skeletal system protects the internal organs and soft tissues and is the structural framework that gives the body its shape. The skeletal system is composed of four parts: bones, cartilage, tendons, and ligaments. The skeletal system provides support, protection, allows body movements, stores minerals and fats, and is the site of blood cell production (Seeley, Stephens, & Tate, 2008). The appropriate development of the skeletal system allows an individual to walk, stand, pick up a pencil, and do everyday activities that involve movement and support. An individual without the appropriate development of the skeletal system will have difficulty performing everyday activities that require movement.
The body works in amazing ways like a fine tuned machine. All organ systems within the body depend on one another for survival in some way or form at all times. Cherif et al., (2010) state, the body depends on the precise action of each organ to maintain physical, mental, and emotional health of a human being. Also, homeostasis, the regulatory of body temperature plays a survival role in maintaining body functions. The integumentary system (skin) is the largest, and the most important part of the body. The skin is just one of the organ systems that will be discussed (Thibodeau & Patton, 2008). The body is expected to perform specific duties at specific times the organ systems as a whole, the most important organ system the integumentary system, and homeostasis, are what enables the body to perform on demand.
Every organ in the human body is composed of one or more tissues. The study of these tissues is known as histology. It is because of histology that the structure of organs can be researched and understood. Since organs are composed of tissues, it is important to understand each tissue type, their structure, their location, and their functions to better understand how each organ operates within the human body.

At the hypothalamus’s signal, one of two types of sweat glands, the eccrine glands, get to work. These sweat glands produce odorless perspiration, a mixture of water, salt and small amounts of other electrolytes, directly onto the skin’s surface. This second type of sweat gland is found predominantly in hair-covered areas, like the scalp, armpits and groin. These
The human body is very complex. It is like a job. You have to do a million things in one day to make it through the day. The body uses nine systems to do all of those jobs. They all have separate functions, but some work together. Each system is also made up of organs. There are many ways to care and protect the systems from the many different problems they can have. There are also many interesting facts about each system.
