Does Dry Shampoo Cause Dandruff? Ever since the day we met, my dry shampoo and I have been attached at the hip. It goes with me everywhereâto the gym, on vacation and even to work! But one day my devotion to it was shaken when a friend said she thought it was causing her dandruff.
duodenum. the first or proximal portion of the small intestine, extending from the pylorus to the jejunum. It plays an important role in digestion of food because the bile and pancreatic ducts empty into it. See also digestive system.
The duodenum [help 1] is the first section of the small intestine in most higher vertebrates, including mammals, reptiles, and birds. In fish, the divisions of the small intestine are not as clear, and the terms anterior intestine or proximal intestine may be used instead of duodenum. In mammals the duodenum may be the principal site for iron absorption. The duodenum precedes the jejunum and ileum and is the shortest part of the small intestine . In humans, the duodenum is a hollow jointed tube about 25â38 cm (10â15 inches) long connecting the stomach to the jejunum.
