Size
The skin is the largest organ of the human body, covering about 2 square meters, and acts as a protective layer for everything inside the body.
Protection
Skin protects the body from injury, germs, and harmful sunlight. It serves as the body’s first defense against external dangers and infections.
Thermoregulation
The skin helps control body temperature by producing sweat and expanding or shrinking blood vessels, keeping the body cool or warm when needed.
Structure
Skin has three layers: the outer layer (epidermis), the middle layer (dermis), and the deepest layer (subcutaneous tissue), each serving different functions.
Vitamin D Synthesis
The skin makes vitamin D when it is exposed to sunlight. This vitamin is essential for healthy bones and the immune system.
Sensation
Nerve endings in the skin allow us to feel touch, pain, heat, and cold. They help us sense the environment and protect from harm.
