I have chosen to do my essay on the largest organ of the body, skin. It has several functions vital to the survival of the body as I will discuss in the following paragraphs. 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 skin is made up of three layers; epidermis, dermis, and subcutaneous layer. The epidermis layer contains stem cells. Stem cells regenerate new skin if the

The first layer, the epidermis, contains keratin which is a water proof protein. This makes the body water proof and keeps water from entering the body. This layer also consist of two specialized cells, langerhans cells and melanocytes. Langerhans cells are macrophages which is a white blood cell that phagocytize infectious agents. They then travel to lymphatic organs. Melanocytes lye deep in the epidermis, and produces melanin. This is the main pigment for skin color. The second layer, the dermis, is a fibrous connective tissue. It is made up of dense fibrous connective tissue and consist of collagen and elastic fibers. The purpose of the collagen fibers are to allow stretching to prevent tearing of the skin; unlike the elastic fibers which only allows for normal tension for stretching, allowing movement of muscles and joints. As we age, the fibers become weaker causing the skin to wrinkle. The blood vessels in the dermis help …show more content…
They have several different factors that determine hair color such as melanin containing iron and sulfur. If there is a lack of melanin, the hair will be white or gray. Stem cells located in the dermis are responsible for the production of hair. The shape and texture of the hair follicle determine an individual’s hair. The growth process of hair goes through the following three phases. The anagen phase which takes approximately twenty eight days and grows about one centimeter. The catagen phase lasts for approximately two to three weeks and the blood supply to the hair is cut off. The telogen phase is the final phase also known as the resting phase, lasting approximately three
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 immune system is made up of a network of cells, tissues, and organs that work together to protect the body, and it defends the body from “foreign invaders.” Immunity can be divided in two three different defenses, and these are defined as first, second and third lines of defense. The first line of defense for the immune system is the primary defense against pathogens entering the body from the surface in order to prevent the start of disease and infection. Some examples of the first line of defense is the skin, protecting the external boundaries of the body, and the mucous membranes, protecting the internal boundaries of the body. Although the skin and mucous membranes work on the internal and external boundaries, they both release chemicals
For my summer assignment, I read the book Skinwalkers by Tony Hillerman. Skinwalkers is about a Navajo police officer named Jim Chee. The story takes place on the Navajo Reservation spanning several states (Arizona, Utah, Colorado, and New Mexico). Throughout the book, Chee works with Lieutenant Joe Leaphorn to solve three seemingly connected homicides. Over the course of the story, the Officers find several strange bits of evidence, such as small bones and strange stories about things happening around the reservation. As the case progresses, Chee and Leaphorn discover that the motive may be much deeper than just hate, it may have to do with witchcraft. As the story concludes, Leaphorn realizes that Chee has been led into a trap and rushes
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 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).
Organic inks, which are my personal professional preference, are the safest on the market. These types of inks are typically derived from plant matter. Vegan inks are also in the same class as the organic inks as well and are also ranked just as safe as organic inks.Organic inks are also safe to digest. I personally have no plans on digesting tattoo ink, but if I planned on doing so at least I know that it is safe.

Our skin functions as a daily defense for our bodies against disease because of skin and mucous membranes. The skin is a massive organ and it protects everything inside our bodies such as our muscles, bones and organs. Our skin protects us from bacteria, parasites, viruses and pathogens ...
Every young girl or woman in America wants their image to look like a Barbie doll. This perfection includes being extremely skinny and extremely tan. In order to achieve this Barbie-like image women and men have been using tanning beds or spray tans to alter their appearance. Tanning beds can prove to be very harmful to a person’s health and can cause extremely dangerous medical conditions, including the most deadly type of cancer. However, fake tans can also be used in a positive way for some people who use them sparingly.
A controversial topic today is whether or not body piercings and tattoos should be accepted by professionals working in health care. Currently, tattoos and piercings are allowed in health care as long as they are not visible. According to one of the studies, “Body piercing is defined as a piercing of the body anywhere other than the earlobes” (Westerfield). Therefore, the only visible piercings allowed are small studs in the lobes of the ears for females. The reason body piercings and tattoos are not suggested in health care is that they keep someone from looking professional as well as making them look intimidating. Not everyone sees them that way. The opposing side is that they do not affect
Hair growth takes place in three phases the anogen phase, the catagen phase, and the telogen phase. The first phase to take place, the anogen stage, can last anywhere from three to seven years. During this stage, hair grows at an average rate of 1 centimeter per month which adds up to around 12 centimeters or 1 inch per year. It is also during this stage that melanin, the pigment that gives hair color, is created. As people get older, follicles gradually give up producing thick, strong hair. As a result, hair becomes thinner and shorter; baldness may even occur. The next phase in hair growth is the catagen phase which takes place anywhere from two to four weeks. During this stage, the base of the follicle moves from underneath the skin to the face and rests near the opening of the sebaceous duct until it is ready to begin growing. This growing takes place during the telogen phase which lasts anywhere from three to four months. During this stage, new hair begins to grow from the hair follicle. As it grows upwards, the old hair will be shed naturally or may be pulled out. This shedding of telogen hairs happens easily and painlessly; these are the hairs that fall out when a person is shampooi...
Are tattoos a kiss of death at a workplace? According to Student Research Center, nearly 4 out of every 10 Americans in their 30s have been inked. ''In April 2000 15% of Americans were tattooed (which is roughly around 40 million people) (The National Geographic).'There are different types of tattoos, from color to black and white, even glow in the dark. Number of tattoo paralos in the U.S. is 21,000'' (Tattoo Statistics 1) and more is being added every single day. People spend about $1.6 billion on tattoos once a year. ''In the U.S. more women than men are tattooed, 36% of the ages is between 18-25 and 40% of those ages are 26-40 that have at least one tattoo.''(Random facts 1) People have been getting tattoos for a while now. It has been said that ''tattoos date back as far as the Neolithic era or around the fourth to fifth millennium BC.''(skinsight.com 1) Tattoos should be acceptable at a place of business because people get tattoos for significant purposes, tattoos can tell stories and build confidence, body art is a way for someone to express themselves, make up, and tattoos are reminders of life time experiences.
The skin has 3 main function. It has to regulate body temperature, remove waste (perspiration), and protect. The skin is made up of 3 layers. The epidermis is the outer thinner layer of the skin that is made up of dead and living cells. The dermis is the thicker middle layer of the skin that contains blood vessels and nerves. Sweat glands are found in the dermis, they secrete perspiration through ducts to pores on the skin’s surface. To avoid problems like warts, boils, moles, acne, and sunburn you can wash your body daily, wear sunscreen that is 15 or higher, and check your body often...
Dry skin is one of the more common side effects of most forms of cancer treatment, including both radiation therapy and chemotherapy. While there are many other causes of dry skin, it is one of the more common issues cancer patients must learn to cope with as a routine part of their treatment.
The concept of “beauty” is something that everyone feels, thinks, or wants, in order to fit society’s standards. In today’s society, we are often faced with the unrealistic ideals of what beauty is. Due to society’s constant portraying of unrealistic beauty ideals, this reinforces a negative influence upon women’s idea of beauty, resulting in a negative impact in their confidence, and self-esteem, which leads to others, specifically women to be manipulated by society’s corrupted outlook of what beauty is. To add onto this issue, we are constantly surrounded by sources of this negative influence in our everyday lives, including magazines, television, advertisements, and so on. However, women specifically, are more prone to be victims of this negative effect, thus will have more pressure upon themselves to match society’s idea of “beauty,” which includes unrealistic and sometimes unattainable beauty standards. Women especially, can sometimes be so deeply manipulated by society’s unrealistic ideals of what is beautiful, such that it’s possible that they don’t even realize it Furthermore, in order to do so, women often will receive negative impacts rather than positive impacts, such as in their confidence and self-esteem. The negative effects of society’s beauty ideals also lead women to have an overall corrupted idea of what is “beautiful.” Society creates unrealistic ideals of beauty towards women through the media by creating an unrealistic image of what women should look like to be considered beautiful. Men negatively affect women’s idea of beauty by using the unrealistic beauty standards exposed by society which further pressures women to try to fit society’s idea of what is beautiful. Beauty pageants negatively affect women’s ov...
