Structural features of skin:
1. Epidermis: The outermost layer of skin that provides a protective barrier against environmental factors.
2. Dermis: The middle layer of skin that contains blood vessels, nerves, hair follicles, and sweat glands.
3. Hypodermis: The innermost layer of skin that contains fat cells and helps regulate body temperature.
Functional features of skin:
1. Protection: Skin acts as a barrier to protect the body from harmful substances, UV radiation, and pathogens.
2. Sensation: Skin contains nerve endings that allow us to feel touch, pressure, temperature, and pain.
3. Thermoregulation: Skin helps regulate body temperature by controlling the amount of heat lost through sweating and blood flow.
4. Excretion: Skin helps eliminate waste products from the body through sweat glands.
5. Vitamin D synthesis: Skin produces vitamin D when exposed to sunlight, which is essential for bone health.
6. Immune response: Skin plays a role in the body's immune response by detecting and fighting off infections.

Structural Features | Functional Features
---|---|
- Epidermis: Stratified squamous epithelium | - Protection: Forms a barrier against physical, chemical, and microbial damage
- Dermis: Thick layer of connective tissue | - Support: Provides strength and elasticity
- Hypodermis: Layer of adipose tissue | - Insulation: Traps heat and protects against cold
- Hair follicles: Produce hair | - Protection: Insulation, waterproofing
- Nails: Hardened keratinized plates | - Protection: Cushion fingertips and toenails
- Sweat glands: Produce sweat | - Thermoregulation: Assists in cooling the body
- Sebaceous glands: Produce sebum | - Protection: Moisturises the skin and prevents water loss
- Langerhans cells: Immune cells | - Immune defense: Recognize and destroy pathogens
- Blood vessels: Supply nutrients and oxygen | - Homeostasis: Regulates temperature and blood pressure
- Nerves: Transmit sensory information | - Sensation: Detect touch, pain, temperature, and pressure
