1. THE INTEGUMENTARY SYSTEM

2. THE INTEGUMENTARY SYSTEM IS MADE OF THE FOLLOWING: Integument (skin) Hairs Sweat Glands Oil Glands

3. INTEGUMENTARY SYSTEM The skin is the largest organ in the body. It covers an area of 18-20 square feet. The skin weighs approximately 6 pounds.

4. FUNCTIONS OF THE INTEGUMENTARY SYSTEM Protection Excretion Sensation Immunity against disease Maintaining homeostasis

5. LAYERS OF SKIN EPIDERMIS DERMIS SUBCUTANEOUS LAYER (HYPODERMIS)

6. THE EPIDERMIS has 5 layers Stratum Corneum Stratum Lucidum Stratum Granulosum Stratum Spinosum Stratum Basale

7. THE DERMIS Contains many fibers and cells Is made of 2 Regions known as the Papillary Region and Dermal Region

8. PAPILLARY REGION OF THE DERMIS Binds dermis to epidermis Gives skin its toughness and flexibility. Contains blood vessels that supply nutrients to the skin.

9. DERMAL REGION OF DERMIS Sebaceous Glands Sudoriferous Glands Sweat Gland Ducts Sweat Gland Pores Melanocytes Hair Follicles Hair Shaft Arrector Pillae muscle Pacinian & Meisner’s Corpuscles

10. THE SUBCUTANEOUS LAYER This lies beneath the dermis and consists of loose connective tissue and adipose tissue. It helps insulate the body and conserve heat.
