What is Earth's largest organ?

Explanation:
An organ is a structure made of tissues that works together to perform specific functions. The skin fits this definition and, by covering the entire exterior of the body, it has the greatest surface area and mass of any organ. That expansive coverage makes skin the largest organ overall. Inside the body, other organs like the liver are large, but they don’t surpass the skin in total size. Skin isn’t just a barrier; it also regulates temperature, senses touch, and helps keep the body protected and hydrated. So the answer is skin because it is the body’s largest organ by size and weight.
