Question

the long structure of small intestine is accommodated in small space in our body comments​

Answer 1

Answer:

Small intestine, a long, narrow, folded or coiled tube extending from the stomach to the large intestine; it is the region where most digestion and absorption of food takes place. It is about 6.7 to 7.6 metres (22 to 25 feet) long, highly convoluted, and contained in the central and lower abdominal cavity. A thin membranous material, the mesentery, supports and somewhat suspends the intestines. The mesentery contains areas of fat that help retain heat in the organs, as well as an extensive web of blood vessels. Nerves lead to the small intestine from two divisions of the autonomic nervous system: parasympathetic nerves initiate muscular contractions that move food along the tract (peristalsis), and sympathetic nerves suppress intestinal movements.

Answer 2

Explanation:

The small intestine is the most important part of the digestive system where digestion and absorption of nutrients take place. The small intestine in adults is a long and narrow tube about 7 meters (23 feet) long. The large intestine is so called because it is wide in diameter as compared to the small intestine. The small intestine can be divided into 3 major regions such as duodenum, jejunum, and ileum.
