The integumentary system is an organ system that is often overlooked when compared to other major organ systems. The importance of the integumentary system and its role in thermoregulation and its first line protection for the body is of utmost importance. The integumentary system includes the following organs: skin, hair, nails, and exocrine glands. Skin is a very large organ, and is the most important organ of the integumentary system. The surface area of skin is about 20 square feet, and weighs about 10 pounds. The importance of skin is to protect the body from UV light, chemical, disease and physical trauma that can occur to the body. The skin helps regulate body temperature. It does this through storage of adipose tissue and through secretions of sweat. It also allows for sensing touch, Different temperatures that the body comes into contact with are sensed and these messages are sent to the brain so that a reaction can occur in order to protect the body. A very important part of the integumentary system is that it is responsible for making vitamin D. Vitamin D is key in the function of calcium absorption.
Skin Skin has three layers. The superior part of the skin in the epidermis.
A medical professional, especially when treating a patient would need to know the location in reference to other organ structures. Many medications are given through subcutaneous injection and the medical professional needs to understand the exact location in which the medication needs to be injected into. For instance, insulin is given for diabetes. A medical professional would need to know that the injection is to be given subcutaneously. Another medication used often in the medical community is the TB test. This is to be injected intra-dermal. Medical practitioners must use correct anatomical positions in order to treat patients
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
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)
The system of the body that consists of bones, connective tissues, and cartilage is known as the skeletal system. Some major functions of this system are as follows:
and support, allows us to manipulate our surroundings and - due to its high metabolic activity - produces heat.” (study.com-Dec 2014)
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).
It is made mostly of connective tissue (areolar and dense irregular). Connective tissue provides support to the epidermis because it consists of numerous collagen and elastin fibers. The dermis serves as a first line of protection so that pathogens (bacteria and/or microbes) that have made it through the epidermis cannot move any farther. The dermis produces a gel-like substance within the areolar connective tissue that slows down the movement of microbes. The dermis also supplies blood and nutrients to the epidermis (via blood vessels) and supports sensory reception (nerve fibers). Accessory structures found in the dermis include a portion of the hair follicle, secretory glands (sebaceous and sweat glands), touch receptors (nerve fibers) and blood vessels. There dermis has two layers: the papillary layer and reticular layer. The papillary layer is the outer top portion of the dermis that is below (deep to) the epidermis. It has a sub layer called dermal papillae. Dermal papillae has ridge-like projections that interlock with ridges in the lower portion of the epidermis (epidermal ridges). These ridge-like projections have sensory receptors and capillaries. The sensory receptors are called tactile corpuscles that detect light, delicate touch and capillaries supply blood and nutrients to the epidermis above. The reticular layer is the deeper portion of the dermis and consists mostly of dense irregular connective tissue (ground substance and randomly arranged collagen fibers). The lamellated corpusle is a large, leaflet like sensory receptor located in the reticular layer. This receptor detects pressure, rough touch and
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.
An ostomy is a surgically formed opening from the inside of the body to the outside of the body. In this procedure, the intestinal mucosa is brought out to the abdominal wall. A stoma, which is attached to the skin, is formed by stitching the mucosa to the skin. There are different types of ostomy procedures performed such as an ileostomy and a colostomy. Ostomy surgery is vital for patients to perform fecal elimination.
The skin is an elastic covering that protects the body against exposure to dangers within our environment and makes up 15% of the weight of the body. It minimizes water loss, repels water and protects underlying structures. The dermis has blood vessels that are close to the surface to allow blood to flow and reduce the temperature of the body. It also acts as a third kidney that filters and excretes toxins.
The human body is a network of muscles, bones, organs and overall, it is constantly working in its own ways to make sure that the body is performs and functions properly. The most important systems in the body, the nervous and endocrine system, both play huge roles in regulating the biological processes inside an organism. They are the basic systems that pretty much control the body, helping it react properly to any external factor. The main difference between these two systems is that the nervous system uses impulses to control the muscles while the endocrine uses chemical stimuli to pass the signal to the target cells or organs. These two systems have their
The skin is the largest organ in the body and everybody's got one. So why not take good care of it? Often, the skin says more about your skin care routine than it does about your age. Caring for your skin, whether you are male or female should be something that you pick up early in life. Why wait until it is too late when you can actually do a lot of things about it now?
Possibly the most essential body system is the circulatory system. It directly affects every other system. The circulatory system is made up of the heart, blood, arteries, and veins. The heart pumps the blood through the arteries to provide blood to other organs. The blood carries oxygen which is necessary for our organs to function and survive. The blood then returns with low amounts of oxygen to the heart and is sent through the process again after receiving oxygen from the lungs. It is extremely important to keep the circulatory system healthy. You can do this by eating low fat and low sodium foods as well as staying active. If you want to stay healthy, you should avoid stress and sitting for too long. It is also harmful
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.
It is thus concerned with brain cells, brain structures and components, brain chemistry, and how all this leads to speech and action. It is also important to understand how we take in information from our five senses.
