Bile and Pancreatic Juice
Bile and pancreatic juice are the two substances added to the food in the small intestine to aid digestion.
Together, bile and pancreatic juice play a crucial role in the digestion and absorption of nutrients in the small intestine. They work synergistically to ensure that fats, proteins, and carbohydrates are broken down efficiently, allowing the body to extract essential nutrients for energy and growth.
Bile and pancreatic juice are the two substances added to the food in the small intestine to aid digestion.
- Bile: Bile is produced by the liver and stored in the gallbladder. It contains bile acids which help emulsify fats, breaking them down into smaller droplets. This process increases the surface area of the fats, making it easier for enzymes to digest them.
- Pancreatic Juice: Pancreatic juice is produced by the pancreas and contains enzymes such as amylase, protease, and lipase. These enzymes help break down carbohydrates, proteins, and fats into smaller molecules that can be absorbed by the body. The pancreas also releases bicarbonate ions to neutralize the acidic chyme coming from the stomach, creating a more optimal environment for enzyme activity.
