Introduction:
Skin is not only the largest organ on the human body, but it is also the most prominent organ that is in the integumentary system. It works in many aspects of protecting the body underneath against the outside environment. The skin has three main layers; the epidermis, dermis and the hypodermis. Each layer have different physical attributes that aid the skin in its job to protect the organism.
Purpose:
This lab was done to help me understand the layers of the skin and their varying appearances and thicknesses. It also showed how two different abnormalities in cells or layers of the skin can affect and spread through the organism, causing harm.

Skin is the largest organ of the body, covering and protecting the entire surface of the body. The total surface area of skin is around 3000 sq inches or roughly around 19,355 sq cm depending on age, height, and body size. The skin, along with its derivatives, nails, hair, sweat glands, and sebaceous glands forms the integumentary system. Besides providing protection to the body the skin has a host of
The integumentary system is the skin and its derivatives; it provides external protection for the body. Its characteristics are: covers the entire body, accounts for about 7% of total body weight, pliable, yet durable, thickness: 1.5 to 4.0 mm, composed of the epidermis and dermis.
The three layers that make up healthy skin: Epidermis, Dermis and Hypodermis. Epidermis is composed of keratinized, stratified squamous epithelium. This layer provides a thick, water proof protective covering over the underlying skins. The dermis layer is composed of primarily of dense, irregular, fibrous connective tissue that is rich in collagen and elastin. The dermis contains blood vessels, nerve ending, and epidermally derived cutaneous oranges such as sweat glands, sebaceous glands and hair follicles. The last layer is Hypodermis this layer is composed primarily of loose dead skin. The fat layer provides cushioning and insulation for
premature aging of the skin, and skin cancer. Therefore, while this article was useful for
Skin is the largest organ on the body. It has two layers: the thin outer layer is made up of dead skin cells that are constantly shed and replaced by new cells. The thick inner layer is made up of blood vessels, nerves, and hair follicles, which contain glands. The glands in the hair follicles produce an oily substance called sebum, which keeps the skin and hair from drying out. Daily washing will keep the skin on the face and other areas of the body clean by removing the dirt, oil, and dead cells before they can accumulate.

The skin is the largest organ of the body and it acts as a waterproof protector for all of the internal organs, it is comprised of several layers including the Epidermis which is the outer layer and is a protective multi-layered self renewing structure which varies in thickness depending on which part of the body it covers. Under this is the Dermis, this is a layer of connective tissue which provides the skins elasticity and strength, it also contains sensory nerve endings, blood and lymph vessels, sebaceous and sweat glands. Under this layer is the Subcutaneous fat layer, this layer separates the skin from the underlying bone and muscle with a rich blood supply it also serves as an insulator and energy store. Pressure ulcers develop
The integumentary system is the organ system that protects the body from damage, and consists of skin and its appendages: hair, nails, sebaceous glands and sweat glands. The skin is our body’s covering, and is the largest organ of the body.
The Integumentary System, also known as the skin, is the largest organ of the body. Its complete structure is composed of many different tissues. The skin protects the cow’s body from any bacterial invasions and physical damage. When a cow becomes sick, the skin is the first system that is affected. The integumentary system is composed of three layers: (i) Epidermis, (ii) Dermis, and (iii) Hypodermis or Subcutis. To start with the inner most layer you have the Hypodermis (Subcutis). The Hypodermis consists of connective tissues, elastic fibers and fat. When fat forms a layer of thickness it is called Peniculus Adiposus. Any reserved energy is also stored within the Hypodermis. Then you have the layer, Dermis. The Dermis supports the outer most layer, Epidermis. Dermis consist of collagen, reticular and elastic fibers which plays a large role in the strength and elasticity in the skin; as well as the maintenance and repair of the skin. Lastly, you have the Epidermis. The Epidermis alone consist of four sublayers, (i) Stratum Corneum – outermost horny layer, (ii) Stratum Lucidum – clear layer, (iii) Stratum Granulosum – granular layer, and (iv) Stratum Spinosum – prickly cell layer. The Epidermis is derived from basal membrane Stratum Basale, which presents the openings for the hair follicles. Some of the functions of the skin include: preservation of the cow’s shape, protection from water loss, protection from any physical, chemical and microbial injury imposed by an external agent. An important role of the skin is it balances its Thermoregulation, which is its ability of an organism to regulate its body
Skin cancer is a disease that can affect any one. Skin cancer includes many types that can be classified as severe or superficial. Consequently, treatement of skin cancer depends on the degree of severity a person has. In the following paper, we will shed lights on the types of skin cancer and its causes. Finally, we will investigate how to treat the different types of cancer and how to avoid it.
The skin is a living organ that covers the entire surface of the body. Surface capillaries allow substances to enter the blood stream and circulate around the body, skin also regulates body temperature for example, when the body gets too cold or too hot the brain will send impulses to the skin to let it know whether to increase or decrease heat loss from the surface of the body. When the body becomes too hot the capillaries dilate and more blood is moved to the surface through the circulatory system, heat will be released through the pores allowing the body to cool down. When the body becomes too cold again the blood is circulated to the major organs inorder to keep them warm. With the blood is re-directed, allows the capillaries and pores
The integumentary system is made of the biggest organ in the body which is the skin.This organ helps to protect the rest of the body from microbes and other harmful elements. It is, literally, a physical barrier to the environment and it absorbs nutrients from the sun and other sources. Also, the skin permits the sensation of touch, heat and cold but most important, it helps to regulate body temperature. This organ makes up to 12% -15% of body weight and its surface is about 1-2 meter. Because the skin it’s in a constant state of change; the cells of the outer layers are continuously shedding and they are replaced by inner cells moving up to the surface, it is said to be a dynamic
Generally this means a pleasing appearance is not a guide to character. In this case, we
I learned in class that the skin is the larger human organ we have. The skin protects us from microbes and the elements, helps regulate body temperature, and permits the sensations of touch, heat, and cold. Touching is one of ways a child bonds with their parents and they beginnings to know if they are liked or disliked.
The integumentary system also known as skin; surrounds the entire human body therefore being the largest organ. The skin and its annexes like hair, sweat glands, sebaceous glands, nails, etc. The main functions of the integumentary system is to function as a protective barrier, that keeps our body free from intrusion of foreign materials, microorganisms and prevents dehydration as well as protecting from desiccation and there are other functions also helps in elimination of waste products and in the regulation of our body tempeture. There are many other functions of the integumentary system and each organ involved in this system has its own particular use
