The longest part of the human body is the small intestine. While the femur (thigh bone) is the longest bone, the small intestine, when uncoiled, can reach up to 20 feet in length! It's responsible for absorbing nutrients from the food we eat.
The colon is the longest part of the large intestine, which is a tube-like organ connected to the small intestine at one end and the anus at the other. It's important to note that while the small intestine is the longest overall, different parts of the body can have different lengths depending on the specific anatomical feature being considered, such as organs, muscles, or bones.
