The secretions of the stomach are acidic. The acid is too strong than you can imagine. The pH is as low as 2. The secretions of the stomach remain acidic till the mid-part of the second part of the duodenum. Here the alkaline secretions of the liver and the pancreas enter the duodenum to counter the acidic secretions of the stomach.
No, the small intestine do not need an acidic environment in order to work. Acid works in stomach to partially digest the food. In the small intestines, fats are digested using bile from the gallbladder which is not acidic.
The release of enterokinase is stimulated by the presence of acidic chyme in the small intestine. This triggers the release of enterokinase from the duodenal mucosal cells, which then activates trypsinogen to trypsin in the small intestine.
The bicarbonate found in the small intestine comes from the pancreas. The pancreas releases bicarbonate ions into the small intestine to help neutralize the acidic chyme that comes from the stomach. This bicarbonate helps create a more optimal pH environment for the enzymes in the small intestine to function properly in the digestion process.
The digestion of food in mouth and stomach and also in small intestine is not neutral , it is either acidic or basic.
Food enters the small intestine first. It enters the duodenum in the small intestine.

Secretin is a hormone released by the small intestine in response to acidic chyme entering from the stomach. It stimulates the pancreas to release bicarbonate-rich pancreatic juice, which helps neutralize the acidity of the chyme, creating a more optimal pH environment for digestion in the small intestine. This process protects the small intestine from damage caused by the acidic chyme.
Sodium bicarbonate is released into the small intestine to neutralize the acidic chyme coming from the stomach, creating a more optimal pH environment for digestion and absorption of nutrients in the small intestine.
Alkaline pancreatic juices are secreted into the small intestine and neutralize the acidic chyme.
The release of enterokinase is stimulated by the presence of acidic chyme in the small intestine. This triggers the release of enterokinase from the duodenal mucosal cells, which then activates trypsinogen to trypsin in the small intestine.
The bicarbonate found in the small intestine comes from the pancreas. The pancreas releases bicarbonate ions into the small intestine to help neutralize the acidic chyme that comes from the stomach. This bicarbonate helps create a more optimal pH environment for the enzymes in the small intestine to function properly in the digestion process.
The pH in the mouth is around 6.5-7.5, slightly acidic due to bacteria and food breakdown. The stomach has a highly acidic pH of 1.5-3.5 to aid digestion. The small intestine has a pH of 7-8, which is more alkaline to neutralize the acidic chyme from the stomach and facilitate nutrient absorption.
Bile released from the gallbladder into the duodenum --Bile from the gallbladder mainly serves to emulsify fats. It does serve neutralization purposes distally in the ileum. The main buffers of acidic chyme as it moves from the stomach to the first part of the small intestine, the duodenum, are pancreatic bicarbonate and secretions from the submucosal Von Brunners glands. The Goblet cells of the duodenal epithelium secrete mucus which helps to protect the small intestine from damage from the acidic chyme as well.
because of it low pH(making it acidic), the duodenum (the first section of the small intestine) secretes cholecystokinin (CCK), which causes the gallbladder to secrete bile.
Food mixed with acid passes from the stomach into the small intestine. Here, the acidic food is neutralized by pancreatic enzymes and bile from the liver. This process prepares the food for the absorption of nutrients in the small intestine.
