Which of the following converts acidic food into alkaline in the alimentary canal?

Correct option is D

Correct Answer: (D) Bile Juice

Explanation:

• Bile juice plays a crucial role in converting acidic food into alkaline in the alimentary canal.
• After food passes from the stomach, which secretes gastric juice (containing hydrochloric acid), it enters the duodenum (the first part of the small intestine).
• Here, bile (produced by the liver and stored in the gallbladder) is secreted into the duodenum.
• Bile is alkaline in nature, and it helps neutralize the acidity of the stomach contents, creating an optimal pH for the action of digestive enzymes in the small intestine.

Other Options:

• Pancreatic Juice: Pancreatic juice is also alkaline and helps neutralize the acidic contents entering the duodenum, but its primary role is in digesting carbohydrates, proteins, and fats.
•  Intestinal Juice: Intestinal juice also has an alkaline nature, helping in digestion and neutralizing stomach acids, but it does not directly neutralize the acidity of the food as much as bile does.
•  Gastric Juice: Gastric juice is acidic, containing hydrochloric acid, which helps in breaking down food in the stomach.
