The small intestine connects to the large intestine about a hands length beneath the liver. The portion of the S.I. is called the ileum and the portion it joins to is the cecum. A sphincter connects the two, preventing back flow. Below the junction is the appendix, which is essentially the tapering off of the large intestine into a rat tail like shape. Matter is supposed to continue up through this part of L.I. hence it's named the ascending colon.
The Ileum!The jejunum is before the ileum, & the cecum is after the ileum.
The duodenum is the first portion of the small intestine. The jejunum is the middle portion of the small intestine. And the ileum is the last and longest portion of the small intestine, extends from the jejunum to the cecum of the large intestine.
The small intestine and large intestine are connected. The area where they connect is around the appendix in the lower right portion of the abdomen.
The ileum of the small intestine is directly attached to the large intestine. It forms the majority of the small intestine. It is C-shaped and short. It is the middle portion of the small intestine. It is at the beginning of the small intestine.
The cecum is located in the first part of the large intestine. This serves as a connection between the ileum to the ascending colon and a part of the intestine that moves the waste to be excreted.
The small intestines joins the large intestines at the cecum. The cecum isn't really a pouch, but the appendix, which is a pouch, is also attached to the cecum.
The ilium is about 3 meters long, and contains villi similar to the jejunum. It absorbs mainly vitamin B12 and bile acids, as well as any other remaining nutrients. It joins to the cecum of the large intestine at the ileocecal junction.
The duodenum is only the first portion of the small intestine. The small intestine comprises the duodenum, the jejunum, and the ileum. Following the ileum of the small intestine is the ileocecal valve, which separates the small intestine from the large intestine. The duodenum is separated from the stomach by the pyloric sphincter.
The iliocecal sphincterThe ileum is the last (and longest) portion of small intestine. It empties into into the cecum (the first part of the "large intestine") at the iliocecal junction. The iliocecal sphincter is a ring of invountary smooth muscle at this junction, controlling the passage of digestive contents from the small intestine to the large intestine.
The small intestine- duodenum, jejuneum, and ileum.
the jejunum is the middle portion of the small intestine
