Answer:
The skin
Explanation:
The skin covers the entire body, making it the largest organ overall.
The skin consists of three layers: the epidermis, dermis, and subcutaneous tissue.
It contains hair follicles, sweat glands, blood vessels, and nerve endings.
The skin has several crucial roles:
Protection: Shields against physical injury, pathogens, and UV radiation.
Temperature regulation: Helps maintain body temperature.
Sensation: Contains sensory receptors for touch, pressure, pain, and temperature.
Excretion: Eliminates waste products through sweat.
Vitamin D synthesis: Sun exposure triggers vitamin D production in the skin.
