HUMAN INTEGUMENTARY

SYSTEM

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.

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.

FUNCTIONS The human integumentary system’s main role is to

defend your body from the external world. The functions of the integumentary system include:

Preserving body liquids

Guarding against diseases, infections, bacterium, and viruses

Removing waste products Controlling body temperature Protecting living tissues and organs in the body Protecting the body from rapid temperature changes

and UV radiation Acting as a sensor for touch, pressure, pain, and cold

and hot temperatures Storing water, fat, glucose, and vitamin D Preventing dehydration

PARTS OF THE INTEGUMENTARY SYSTEM

Skin Hair Nails Glands Nerve Receptors

SKIN

Epidermis: Uppermost layer of skin

Mostly waterproof

Responsible for skin pigmentation

Protects the skin from UV radiation

Assists the immune system in

fighting off pathogens

SKIN

Dermis: Layer beneath the epidermis

Consists of the papillary and reticular layers

Allows for stretching

Works to prevent wrinkling and sagging

Fights off infections and unknown substances

Contains glands

SKIN

Hypodermis: Third layer of skin

Responsible for protecting the body

Cushions the bodies’ organs

Made of tissues that store extra energy as fat

HAIR

Covers most of the body Shields the body from UV radiation Insulates the body by trapping in heat Made up of the follicle, root, and shaft

NAILS

Located on the tips of fingers and toes Protects the ends of the fingers and toes Used as tools Consists of the root, body and free edge

GLANDS

Sudoriferous Glands (Sweat Glands) Located in the dermis of the skin Eccrine sweat glands:

Located in most every part of the body

Let off water and sodium chloride to cool the body down

Apocrine Sweat Glands: Found in pubic areas of the body

Emit oils near the hair shaft that produce a body odor

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 feet Produce a discharge called sebum that is

waterproof and allows the skin to stretch Lubricate hair cuticles

GLANDS

Ceruminous Glands Located in the dermis of ear canals Create a waxy discharge to shield the ear

canal from dust particles and pathogens Lubricate the eardrum

NERVE RECEPTORS

Responsible for sensing touch (pain, pressure, and temperature)

Communicate with the nervous system about the external environment

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.

CONCLUSION

This 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.
