The correct answer is: D) secretin
Gastric secretion is highly regulated whether its secretion should be increased (when food is eaten) or decresed (as the stomach empties). Secretion is controlled by the nervous system and endocrine system that work together. There are three phases of gastric secretory control:
Cephalic-by the brain
Gastric-by the stomach itself
Intestinal- by the small intestine
All of three can work simultaneously.
Secretin is released by duodenal enteroendocrine cells and it stimulates the pancreas and gall bladder, but also suppresss gastric secretion and motility. Secretion of the secretin is stimulated by the chime and it is the part of intestinal phase.
Answer:
C3 photosynthesis produces a three-carbon compound via the Calvin cycle while C4 photosynthesis makes an intermediate four-carbon compound that splits into a three-carbon compound for the Calvin cycle. Plants that use CAM photosynthesis gather sunlight during the day and fix carbon dioxide molecules at night.

<span>Hi,
The food is chewed and grinned up from the teeth and broken down from saliva, then the epiglottis shuts covering the trachea allowing food to travel
down the esophagus, once it travels down it reaches the stomach which is mechanically and chemically broken down from the stomach muscles and the hydrochloric acid. Then it goes into small intestine, then the large intestine where it is determined to be a solid, liquid, or gas and the liquid is normally drained out causing it to be solid, Then it is eventually stored in the rectum and released through the anus. There are three helping organs the liver, gallbladder, and pancreas which produce the digestive enzymes but arent part of the digestive tract,
