duodenum The first and shortest portion of the small intestine lying between the pyloric end of the stomach and the jejunum.
duplications The presence of two copies of one or more loci in a chromosome.
dura mater The outermost meninx.
Two ducts enter the duodenum:
one draining the gall bladder and hence the liver
the other draining the exocrine portion of the pancreas.
The head of the pancreas is encircled by the duodenum and its tail touches the spleen.
The upper part, the duodenum, is the most active in digestion. Secretions from the liver and pancreas are used for digestion in the duodenum. Epithelial cells of the duodenum secrete a watery mucus.
The flagellated corkscrew-shaped bacterium, Helicobacter pylori, apparently survives in the forbidding acid environment of the stomach and duodenum by hiding in the mucus and neutralizing stomach acid in its local environment.
The pattern of secretion of gastrointestinal hormones is changed by the bypass and removal of the duodenum and proximal jejunum, which together form the upper (proximal) part of the small intestine.
This makes sense because pepsin is an enzyme that is normally found in the stomach where the pH is low due to the presence of hydrochloric acid. Trypsin is found in the duodenum, and therefore, ...
