Each of the movements of the previous question pushes a small amount of chyme through the pyloric sphincter into duedenum, this process is called?
Gastric emptying
This accessory digestive organ lies posterior to the stomach and secrets digestive enzymes into the duodenum to aid digestion in the small intestine.

Acini

Gallstones

Small intestine
Which portion of the small intestine is in the left upper quadrant?
Jejunum
The last portion of the small intestine joins with the large intestine, is mostly in the right lower quadrant.
Ileum
The sphincter between the small and large intestine is?
Illeocecal sphincter
About how long does chyme remain in the small intestine?
3-5 hours
What percentage of digestive absorption occurs in the small intestine?
90%
The large major part of the GI tract is? It’s four regions are the cecum, colon, rectum, and anal canal.
Large intestine
Attached to the cecum of the large intestine is a cooked tube, which controls bacteria entering large intestine via immune responses, is called?
Vermiform appendix
The longest portion of the large intestine is? Divided into ascending, transverse, descending, and sigmoid.
Colon
The longitudinal outer bands of the large intestine are called?
Teniae coli
The colon is gathered into series of pouches called?
Haustra
Name the phase of digestion charaterized by the smell, sight, sound, or thought of food activating neural centers in the brain.
Cephalic phase
Name the phase of digestion where food hits the stomach, thereby starting digestion.
Gastric phase
Name the phase of digestion when food chyme enters the small intestine.
Intestinal phase
