Really there is no 'structure' as such between the small and large intestine. The small intestine is in three parts (that are not separated/divided), the first 20cm or so is the duodenum, the next roughly 2.5m is the jejunum with the remaining roughly 3.5m the ileum which then turns into cecum (the first part of the large intestine). Imagine the intestines as piping with each part being another pipe welded to the last - there are different sections but ultimately they form one long tube.
Iliocecal valve
Actually The small intestine is not connected to the stomach. Between the stomach and the small intestine is the Duodendum. At the end of the small intestine the colon, or large intestine begins.
No, the large intestine is between the small intestine and the anus.
ileocecal valve
* Part of digestive system * intestines * absorb (small=nutrients large=water)
The sphincter muscle, or ileocecal valve is located at the junction of the small and large intestine.
Ileocecal valve
The small intestine.
The duodenum is the first part of the small intestine and it is about 20 feet from the beginning of the large intestine.
Caecum
The sphincter muscle, or ileocecal valve is located at the junction of the small and large intestine.
The small intestine is said to be small because it's diameter is not as large as the large intestine.
