S cells are cells which release secretin, found in the jejunum and duodenum. They are stimulated by a drop in pH in the small intestine's lumen. The released secretin will increase the secretion of HCO3- into the lumen. Secretin is a hormone produced in the S cells of the duodenum in response to low duodenum pH and fatty acids in the duodenum to stimulate the secretion of bicarbonate from bicarbonate producing organs(liver, pancreas, Brunners glands) when the pH drops below a set value. ... Diagram of the Human Intestine In anatomy of the digestive system, the jejunum is the central of the three divisions of the small intestine and lies between the duodenum and the ileum. ... In anatomy of the digestive system, the duodenum is a hollow jointed tube that connects the stomach to the jejunum. ... click here for more info The title of this article is incorrect because of technical limitations. ... Diagram showing the poop shoot In biology the small intestine is the part of the gastrointestinal tract between the stomach and the large intestine (colon). ...

Secretin is a hormone produced in the S cells of the duodenum in response to low duodenum pH and fatty acids in the duodenum to stimulate the secretion of bicarbonate from bicarbonate producing organs(liver, pancreas, Brunners glands) when the pH drops below a set value. ...
The cytoplasm of a cell is surrounded by a plasma membrane.
This membrane serves to separate and protect a cell from its surrounding environment and is made mostly from a double layer of lipids (hydrophobic fat-like molecules) and hydrophilic phosphorous molecules.
The cytoskeleton acts to organize and maintain the cell's shape; anchors organelles in place; helps during endocytosis, the uptake of external materials by a cell, and cytokinesis, the separation of daughter cells after cell division; and moves parts of the cell in processes of growth and mobility.
Cell is a microprocessor architecture jointly developed by a Sony, Toshiba, and IBM alliance known as STI.
The Cell architecture breaks ground in combining a light-weight general-purpose processor with multiple GPU-like coprocessors into a coordinated whole, a feat which involves a novel memory coherence architecture for which IBM received many patents.
In the Cell the problem has been reversed: reading the data is no longer the difficult problem due to the complex encodings used in industry; today the problem is efficiently decoding that data into an ever-less-compressed version as quickly as possible.
