kindly ask the questions separately(4 MCQs at a time) and not all together
1) a pancreas
2)d localised mechanical digestion of chyme in the small intestine.
This process occurs via contractions of circular muscles, happens in both directions and works to mix the chyme with the digestive juices
3) e CCK.It inhibits gastric emptying
4 a Buffer of HCl in gastric juice
Bicarbonate is produced by the pancreatic acini, secreted into the duodenum via pancreatic duct. Bicarbonate neutralizes the acidity of gastric juices from the stomach and protects the small intestinal muscosa from erosion and ulcers due to the acid
