2 Which part of the digestive tract is the longest?

3 Try to explain why that part is the longest.

Answer 1

Answer:

1) The Small Intestine. It absorbs most of the nurtients in our food. The circulatory system passes them on to other parts of the body to store or use. Special cells help absorbed nutrients cross the intestinal lining into the bloodstream.

2) The small instestine; although the small intestine is  narrower than the large intestine, it is actually the largest section of the digestive system tube, that is measures about 22 feet (or seven meters) on average, or 3 1The /2 times the length of tthe body.

3) The small intestine, despites its name, is the largest part of the gastrointestinal tract. It works with other organs of the digestive system to further digest food after it leaves the stomach and absorbs nurtients.
