Megacolon
the jejunum is the middle portion of the small intestine
In adults the jejunum is found in the small intestine and lies between the duodenum and the ileum. The lining of the jejunum absorbs small food particles which have previously been digested in the duodenum.
The first portion of the large intestine is called the cecum. It connects the small intestine to the colon and is located in the lower right side of the abdomen. The appendix is attached to the cecum.
The portion of the small intestine that attaches to the cecum is the ileum. The connection point is called the ileocecal valve, which regulates the flow of contents from the small intestine into the large intestine.
The suture of the second portion of the small intestine is known as the mesentery. It is a fold of peritoneum that attaches the small intestine to the posterior abdominal wall, providing support and allowing blood vessels, nerves, and lymphatics to reach the intestine.
located in the wall of the distal portion of the small intestine.
The distal coiled portion of the small intestine is called the ileum. It is located between the jejunum and the cecum (the beginning of the large intestine) and is the longest section of the small intestine. The ileum is primarily involved in the absorption of nutrients, especially vitamin B12 and bile salts.
peyer's patches are found in the lowest portion of small intestine.
The cecum is the first portion of the large intestine.
alimentary canal
The Ileum!The jejunum is before the ileum, & the cecum is after the ileum.
Sigmoid colon The final portion of the large intestine that empties into the rectum.
The iliocecal valve is an involuntary smooth muscle sphincter located between the ileum (small intestine) and the secum (portion of large intestine). Its function is to prevent backflow or reflux into the ileum.
the jejunum is the middle portion of the small intestine
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 first portion of the small intestine, the duodenum, is straight. The second portion, the ileum, is coiled.
The ileum is the most distal portion of the small intestine from the pylorus of the stomach. It connects to the large intestine at the ileocecal valve.
