D Correct answer
Explanation

The small intestine is a long, highly convoluted tube in the digestive system that absorbs about 90% of the nutrients from the food we eat. It is given the name because it is only 1 inch in diametre, making it less than half the diametre of the large intestine. The small intestine is, however, about twice the length of the large intestine and usually measures about 10 feet in length.
