Why small intestine is hollow??

1.	Why small intestine is hollow??
Answer» The small intestine is made up of 3 layers,\xa0the duodenum, jejunum, and ileum. It contains enzymes like trypsin and chymotrypsin which breaks down food to the maximum possible with the help of bile from the liver. Peristalsis also takes place\xa0in this organ. The duodenum is largely responsible for the continuous breaking-down process, with the jejunum and ileum mainly responsible for absorption of nutrients into the bloodstream.Contents of the small intestine starts from a semi-solid form till the end in a liquid form after passing through the organ. Once the nutrients have been absorbed and the leftover-food residue liquid has passed through the small intestine, it then moves on to the large intestine, or colon. Stomach Large intestine
