Integumentary SystemConsists of skin and accessory organs
Skin is 2 regions: Dermis epidermis
A fatty layer lies deep (hypodermis)
Hair Follicles Skin Glands Nails
Skin is the body’s outer covering and its largest organ.

Epidermis
Stratified Squamous Epithelium (tissue)
Keratinized: keratin is a tough protein
![Page 8: TODAY Outline chapter 5 Test back Corrections tonight after school, tomorrow at 7:00 am Outline p. 100-105 due tomorrow Project: building day.](https://reader035.fdocuments.in/reader035/viewer/2022062322/56649e9f5503460f94ba15dc/html5/thumbnails/8.jpg)
Keratinized: By the time cells reach surface, little more than keratin filled sacsDesquamification: shedding of outermost layer of a tissue

Epidermis
No direct blood supplyNutrients must diffuse into the epidermis
Four types of cellsKeratinocytes – deepest, produce keratin Melanocytes - make dark skin pigment melanin Merkel cells – associated with sensory nerve endings Langerhans cells – macrophage-like dendritic cells
