All of the following statements concerning this region of the small intestine are true, EXCEPT for . . .Chooe one from the following:(A) This region of the small intestine is the 2nd longest region(B) Peyer's patches are located in the submucosa of this region of the small intestine(C) This region of the small intestine is classified as intraperitoneal(D) Branches of the superior mesenteric artery supplying this region of the small intestine demonstrate multiple levels of arcades(E) Most of the nutrients available to the body after digestive hydrolysis are absorbed across the wall of this region of the small intestine

The digestive system comprises the organs that help in digesting the food, absorption of nutrients from the digested food, and excretion of the waste unabsorbed materials. The digestive system begins with the oral cavity and ends at the anus. The abdominal part of this system is called the gastrointestinal tract that includes the terminal part of the esophagus, stomach, small and large intestines. The accessory organs that help in digestion are the pancreas, liver, gall bladder.The arrow is pointing towards the terminal part of the ileum. The Ileum is the third or the terminal part of the small intestine. The ileum is 3.5 cm in diameter and compared to the jejunum it is thinner and less vascular. It measures about 12 feet in length and is the longest of the small intestine subparts. Peyer's patches are secondary lymphoid tissue and are located in the intestine, they are responsible for immunity. They are present in the submucosa layer of the ileum of the small intestine. The ileum, jejunum, and some parts of the duodenum are intraperitoneal, they are surrounded by the peritoneal layer. Ileal arteries supply the ileum which forms 2 or more arcades and their terminal vasa recta are shorter compared to the jejunum. The ileal branches are from the superior mesentric artery. Bile salts, vitamin B12, and the rest of the nutrients that are not absorbed by jejunum get absorbed in the ileum. The major nutrient absorption takes place in the jejunum followed by the ileum. Therefore, The answer is:- (A) This region of the small intestine is the 2nd longest region (E) Most of the nutrients available to the body after digestive hydrolysis are absorbed across the wall of this region of the small intestine
