Which organ is the largest body organ?

Explanation:
Think about size in terms of coverage and surface area. The skin is the body's largest organ because it covers the entire external surface, creating a vast available area for its many roles. Its surface area is roughly 1.5 to 2 square meters, and it serves as a protective barrier, helps regulate temperature and fluid balance, enables sensation, and participates in vitamin D production. While internal organs like the liver are very large in mass, the skin’s extensive coverage makes it the largest overall organ.
