What is the largest organ in the body?

While thin in thickness, the skin is considered an organ and is therefore the largest in the body because of its great surface area. The skin is an important part of the integumentary system. The small intestine and stomach are both significant organs of the digestive system, but neither are the largest organ of the body. The small intestine where digestion and nutrient absorption occurs is the longest part of the digestive system, while the large intestine is the largest part of the digestive system. The femur is the largest bone in the body, but is not the largest organ.
