Answer :
Final answer:
The liver produces bile, which aids in the digestion and emulsification of fats, as well as helps to neutralize acidic chyme entering from the stomach. The correct option is A.
Explanation:
The substance that is produced by the liver is bile. The liver plays a crucial role in digestion, particularly in the digestion of fats. It produces bile, which is then secreted into the duodenum or stored in the gallbladder.
When fatty food enters the duodenum, bile is released, which helps in breaking down large fat globules into smaller ones, making it easier for fat-digesting enzymes to work.
This process is known as emulsification of fats. Bile also helps to neutralize the acidic chyme that comes from the stomach, creating a more favorable environment for the enzymes in the small intestine to function effectively.
