Question

Where does the remaining gastric juice go after the food enters into small intestine?(or)do the gastric juice along with chyme evenly enters the duodenum?

Answer 1

● When the chyme is completely liquefied with with gastric juices, the pyloric sphincter opens briefly, about three times a minute, to allow small portions of chyme to pass through.

● At the beginning of the small intestine, the chyme bypasses the opening from the common bile duct, which is dripping fluids into the small intestine from two organs outside the GI tract--the gallbladder and the pancreas.

● The chyme travels on down the small intestine through its three segments--the duodenum, the jejunum, and the ileum--almost 10 feet of tubing coiled within the abdomen.

● There, the pancreas contributes digestive juices by way of ducts leading into the duodenum.

● Secretes enzymes that digests all energy-yielding nutrients to smaller nutrient particles.

● Bile also flows into the duodenum.

● The liver continuously produces bile, which is then concentrated and stored in the gallbladder.

● The gallbladder squirts bile into the duodenum of the small intestine when fat arrives there.

● By the time food leaves the stomach, digestion of all three nutrients has begun, and the action gains momentum in the small intestine
