2 IntroductionThroughout this presentation, the audience will develop a better understanding of the human integumentary system as I explain the location of the integumentary system, functions of the system, parts of the system, and diseases that affect this system. I will also use pictures as a visual representation.
3 What is it?The human integumentary system is the biggest organ of humans, and it is made up of the skin, hair, nails, glands, and nerve receptors. It is located on the outside of the body as skin and serves as a protective layer.
4 FunctionsThe human integumentary system’s main role is to defend your body from the external world. The functions of the integumentary system include:Preserving body liquidsGuarding against diseases, infections, bacterium, and virusesRemoving waste productsControlling body temperatureProtecting living tissues and organs in the bodyProtecting the body from rapid temperature changes and UV radiationActing as a sensor for touch, pressure, pain, and cold and hot temperaturesStoring water, fat, glucose, and vitamin DPreventing dehydration
5 Parts of the integumentary System SkinHairNailsGlandsNerve Receptors
6 Skin Epidermis: Uppermost layer of skin Mostly waterproof Responsible for skin pigmentationProtects the skin from UV radiationAssists the immune system infighting off pathogens
7 Skin Dermis: Layer beneath the epidermis Consists of the papillary and reticular layersAllows for stretchingWorks to prevent wrinkling and saggingFights off infections and unknown substancesContains glands
8 Skin Hypodermis: Third layer of skin Responsible for protecting the bodyCushions the bodies’ organsMade of tissues that store extra energy as fat
9 Hair Covers most of the body Shields the body from UV radiation Insulates the body by trapping in heatMade up of the follicle, root, and shaft
10 Nails Located on the tips of fingers and toes Protects the ends of the fingers and toesUsed as toolsConsists of the root, body and free edge
11 glands Sudoriferous Glands (Sweat Glands) Located in the dermis of the skinEccrine sweat glands:Located in most every part of the bodyLet off water and sodium chloride to cool the body downApocrine Sweat Glands:Found in pubic areas of the bodyEmit oils near the hair shaft that produce a body odor
12 glands Sebaceous Glands Located in the dermis of the skin Located everywhere on the body except the insides of the hands and the soles of the feetProduce a discharge called sebum that is waterproof and allows the skin to stretchLubricate hair cuticles
13 glands Ceruminous Glands Located in the dermis of ear canals Create a waxy discharge to shield the ear canal from dust particles and pathogensLubricate the eardrum
14 Nerve receptorsResponsible for sensing touch (pain, pressure, and temperature)Communicate with the nervous system about the external environment
15 Diseases and conditions Melanoma: Skin cancer that appears as a dark, varying, bleeding spot. It is the most dangerous type of skin cancer and can be fatal.Basal Cell Carcinoma: Skin cancer where the skin becomes the color of a pearl. This is the most common type of skin cancer, and it destroys skin tissues and bones. It seldom spreads to other areas of the body. However, if it is not taken care of, it can cause problems.Acne: A very common disorder of the hair and oil glands that causes pimples on the face, chest, and back.Warts: Bumps on the skin (normally on the hands and feet) caused by viral infections.Eczema (Dermatitis):This is dry, red, irritated, and scaly skin that can occur on any part of the body.Vitiligo: A condition in which the skin does not produce melanin, and spots of white skin appear on the body.Psoriasis: Inflamed, red, irritated patches that appear on the knees and elbows.
16 ConclusionThis project greatly expanded my knowledge on the human integumentary system. I learned about the location of the integumentary system, the functions of the system, the parts of the system, and the diseases that affect the system. The information I have collected will be beneficial in future classes that focus on the human body. It will also help me better understand how I am made and the importance of keeping my body and its systems healthy.
