Villi are hairs in the throat that brush up mucus, they get stuck together and become useless if you smoke. The three segments of the small intestine are the Duodenum, the Jejunum and the Lleum.
c. cecum which is the first portion of the large intestine)
the small intestine is subdivided into three parts : duodenum, jejunum and ileum some books mix the jejunum and the ileum togother
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.
Food passes from the stomach to the small intestines where most of the nutrients are broken down and absorbed. From the small intestines the balance of the nutrients move to the large intestine where water is extracted and feces is moved to the rectum.
Yes they do. They have two coeloms (body cavities)
Following after the small intestine is the large intestine (or large bowel).
Anatomically bowel is a synonym for intestine and it is a part of gastrointestinal tract from sphincter pylori of the stomach to the anus. It consists of two segments, the small and the large intestine. Small intestine is subdivided also to duodenum, jejunum and ileum, whereas the large intestine is further subdivided into cecum and colon.
Small intestine
In anatomy, the intestine (or bowel) is the segment of the alimentary canal extending from the stomach to the anus and, in humans and other mammals, consists of two segments, the small intestine and the large intestine. In humans, the small intestine is further subdivided into the duodenum, jejunum and ileum while the large intestine is subdivided into the cecum and colon.
The large intestine, also called the colon, comes next.
Both. Mechanical: Segmentation is a process of pushing the chyme (partially digested food) back and forth in between sections (segments) of the small intestine further breaking down the food mechanically. Chemical: The small intestine receives pancreatic juices and bicarbonate from the pancreas, and bile which was produced in the liver, but gets stored in the gallbladder, and secreted from the gallbladder into the small intestine.
