The integumentary system consists of the skin and its appendages, including hair, glands, and nails, and is made up of three layers: the epidermis, dermis, and hypodermis. Its functions include protection, vitamin D synthesis, temperature regulation, preventing water loss, and sensory reception. Disorders affecting this system include burns, infections, and skin cancer, highlighting its vital role in the protection and survival of the organism.

2. INTRODUCTION
• Integument is skin.
• Skin and its appendages (Hair & Hair follicles, Sebaceous &
Sweat glands and Nails) make up the “integumentary system”.

3. SKIN
Consists of 3 layers:
1. Epidermis - Keratinized stratified squamous
epithelium.
2. Dermis - Strong, flexible connective tissue.
3. Hypodermis (Subcutaneous / superficial fascia) - Fatty
tissue.
Functions:
• Protection
• Synthesizes vitamin-D with UV
• Regulates body heat
• Prevents unnecessary water loss
• Sensory reception (nerve endings)

4. SKIN APPENDAGES
• Hair and hair follicles:
Derived from epidermis and dermis.

5. • Sebaceous (oil) glands:

6. • Sweat glands:

7. • Nails:

8. DISORDERS OF THE INTEGUMENTARY
SYSTEM
• Burns
• Infections
• Skin cancer

9. CONCLUSION
• First line of defense for body.
• Integumentary System is essential for the living organism for
its survival.
