GENERAL HISTOLOGY

Detailed explanation-1: -Secretin stimulates the pancreas to secrete basic juice (rich in HCO3–) and helps to neutralize the acidity of the chyme that has entered the small intestine.

Detailed explanation-2: -In order to neutralize the acidic chyme, a hormone called secretin stimulates the pancreas to produce alkaline bicarbonate solution and deliver it to the duodenum.

Detailed explanation-3: -The duodenum is separated from the stomach by the pyloric sphincter. The chyme is mixed with pancreatic juices, an alkaline solution rich in bicarbonate that neutralizes the acidity of chyme from the stomach.

Detailed explanation-4: -Answer and Explanation: The bicarbonate from the pancreas helps to neutralize the acidic chyme and the bile from the gall bladder aids in the digestion of fat.

Detailed explanation-5: -Chyme passes from the small intestine through the ileocecal valve and into the cecum of the large intestine. Any remaining nutrients and some water are absorbed as peristaltic waves move the chyme into the ascending and transverse colons. This dehydration, combined with peristaltic waves, helps compact the chyme.
