Sphincter controlling the movement of food from the stomach into the duodenum?
Pyloric sphincter controls the movement of food from stomach to duodenum. With parasympathetic or vagal stimulation it opens up or relaxes and with sympathetic stimulation it contracts or closes.
What regulates gastric secretions?
duodenum
Where are the spincters in the digestive system?
1st: inferior esophageal sphincter (near esophagus passin through the diaphragm, prevents the reflux of gastric juices into the esophagus). 2nd: pyloric sphincter (at the pyloric part of stomach, controls the flow of contents from the stomach into the duodenum). 3rd: internal, external anal sphincter (lies in the anal canal and controls the discharge of wastes).
What hormone functions to counteract the effect of gastric acid in the small intestine?
Secretin is a hormone that controls the secretions into the duodenum, and also separately, water homeostasis throughout the body. It is produced in the S cells of the duodenum in the crypts of Lieberkühn.[1] Its effect is to regulate the pH of the duodenal contents via the control of gastric acid secretion and buffering with bicarbonate from the centroacinar cells of the pancreas as well as intercalated ducts. It is notable for being the first hormone to be identified.[2] In humans, the secretin peptide is encoded by the SCT gene

What is the inferior gastric valve that leads into the duodenum?
Pyloric valve
The mixture of food and gastric juice that enters the duodenum is called?
Its chyme.
What phase of the gastric secretion is chyme moved into the duodenum?
intestinal phase
What is the section of the small intestine that receives gastric juices and food from the stomach?
duodenum
Phase of gastric regulation includes inhibition by the enterogastric reflex?
The phase you are referring to is the intestinal phase of gastric regulation. During this phase, the enterogastric reflex inhibits gastric activity in response to the presence of acidic chyme in the duodenum. This helps regulate the rate at which the stomach empties its contents into the small intestine.
What neutralize the gastric juices?
alkaline juices is the duodenum secreted from glands in the gut wall.
What regulates discharge of CHYME into Duodenum?
The discharge of chyme from the stomach into the duodenum is primarily regulated by the pyloric sphincter, which controls the passage of partially digested food. Hormonal signals, particularly the release of secretin and cholecystokinin (CCK) in response to the presence of acidic chyme and fats in the duodenum, also play a crucial role. These hormones help modulate gastric emptying and stimulate the secretion of bile and pancreatic enzymes, ensuring optimal digestion in the small intestine.
