The primary major organ of the digestive tract that absorbs most nutrients is the Large Intestine.

The rectum is considered an accessory organ of the digestive system.

Bicarbonate secretion from the pancreas is stimulated by the hormone cholecystokinin (CCK).

Mass balance in the gastrointestinal tract is defined solely by matching fluid input with solid output.

The enteric nervous system is responsible for regulating gastrointestinal motility.

The primary function of villi in the small intestine is to decrease surface area for nutrient absorption.

The gastrointestinal tract balances fluid intake and secretion to maintain homeostasis.

The organ responsible for the secretion of bile is the colon.

Microvilli are known as brush border and serve to reduce nutrient absorption in the small intestine.

Salivary glands function as major digestive organs in the gastrointestinal system.

Crypts in the small intestine contribute to the structure's ability to absorb nutrients.

Functions of the liver include storing nutrients and detoxifying harmful substances.

Chemical digestion is completely finished in the small intestine before any nutrient absorption occurs.

When pH is less than 4, Secretin is released to stimulate HCO3- .

Acetylcholine is a hormone released during the intestinal phase to stimulate gastric secretion.

Vagus nerve activity promotes gastric emptying during the intestinal phase.

The release of hormones such as CCK and GLP1 facilitates further gastric secretion.

The intestinal phase is characterized by the inhibition of pepsinogen activation by increasing pH levels greater than 4.

The presence of fatty acids in the intestine decreases the secretion of gastric inhibitory peptide (GIP).

The intestinal phase of gastric secretion is triggered by the entry of chyme into the small intestine.

Cholecystokinin (CCK) is released in response to the presence of amino acids and fatty acids in the duodenum.

Proteases convert triglycerides into monoglycerides and fatty acids during digestion.

The cephalic phase of gastric secretion occurs due to the thought of food.

Secretin promotes the secretion of digestive enzymes from the pancreas in response to acidic chyme.

The presence of chyme in the duodenum activates gastric secretion despite it being part of the intestinal phase.

The duodenum is the first part of the small intestine where the intestinal phase of digestion occurs.
