What is the largest organ in body?
The skin is the largest organ in the human body.
What is the organ that covers and protects the body and releases waste from the blood through sweat glands?
The largest organ in the body cavity in a frog is the liver. However, the skin is considered to be the largest organ only that it is not in the body cavity. according to "dissection of a frog" (great fun *sarcasm*) i believe that the liver is the largest organ :) The liver is the largest internal organ in a frog.
