  1. INTEGUMENTARY SYSTEM Easier known as skin BY: JARON ESTEP & PEYTON PATRICK

  2. What the integumentary system does • Protects the body’s internal living tissues and organs • Protects against invasion from harmful organisms • Protects from dehydration • Helps excrete waste through perspiration • Acts as a receptor for touch • Stores water fat glucose and vitamin D

  3. Layers of The integumentary system • Epidermis • Dermis • Hypodermis

  4. Epidermis • The top layer of skin made up of the epithelial cells. • Does not contain blood vessels. • Its main function is protection, absorption of nutrients, and homeostasis. • Its structure consists of a keratinized stratifies squamous epithelium which is made of four types of cells. Keratinocytes, melanocytes, merkel cells, and langerhans’ cells.

  5. Dermis • The dermis is the middle layer of skin • Composed of dense irregular connective tissue and areolar connective tissue such as collagen. • The dermis has two layers • One is a papillary layer • The other is a reticular layer • The dermal layers provide a site for the endings of blood vessels and nerves

  6. Hypodermis • Also called hypoderm, subcutaneous tissue, or superficial fascia and the bottom layer of the integumentary system. • Types of cells that are found in the hypodermis are fibroblasts, adipose cells, and macrophages. • It is derived from the mesoderm, but not the dermatome region of the mesoderm

  7. Some Skin Diseases • Rash • Blister • Sunburn • albinism • Herpes • Cancer • Psoriasis

  8. Rash • A change in skin which affects its color appearance or texture

  9. Blisters • A blister is a small pocket of fluid in the upper layer of the skin

  10. sunburn • A sunburn is a form of radiation burn that affects living tissue from an overexposure to ultraviolet light

  11. Albinism • A congenital disorder characterized by the complete of partial absence of pigment in the skin.

  12. Herpes • Is a viral disease from the herpesviridae family caused by both herpes simplex virus type 1 and type 2 • There is two main types of herpes: oral herpes, and genital herpes
