Which organ is considered the largest in the human body?

The skin is considered the largest organ in the human body due to its extensive coverage, accounting for about 15% of an individual's total body weight and covering an average area of about 22 square feet. It serves vital functions, including protection from environmental hazards, regulation of body temperature, and sensation through its rich supply of nerves and receptors.

The skin's layered structure, including the epidermis, dermis, and subcutaneous tissue, allows it to perform these functions effectively. This organ plays a crucial role in maintaining overall health and homeostasis. Understanding the significance of the skin's size and functions is fundamental for estheticians, as they work to promote skin health and address various skin concerns.
