Enzymes and Juices for Digestion

Saliva
- Saliva contains an enzyme called amylase, which helps break down carbohydrates into simpler sugars like glucose. This process starts in the mouth as we chew our food.

Gastric Juice
- Gastric juice produced by the stomach contains hydrochloric acid and the enzyme pepsin. Hydrochloric acid helps to break down food and kill bacteria, while pepsin breaks down proteins into peptides.

Pancreatic Juices
- The pancreas produces pancreatic juice, which contains several enzymes such as amylase, lipase, and proteases. Amylase helps digest carbohydrates, lipase breaks down fats, and proteases break down proteins.

Bile
- Bile is produced by the liver and stored in the gallbladder. It is released into the small intestine to help digest fats. Bile emulsifies fats, breaking them down into smaller droplets that can be more easily digested by enzymes.

Intestinal Juices
- The small intestine produces intestinal juices that contain enzymes like peptidases, sucrase, maltase, and lactase. These enzymes help further break down peptides into amino acids and disaccharides into monosaccharides for absorption.

In conclusion, our body produces a variety of enzymes and juices to digest different nutrients, starting from the mouth with saliva breaking down carbohydrates, to the stomach with gastric juice digesting proteins, and finally to the small intestine with pancreatic and intestinal juices breaking down fats, proteins, and carbohydrates further for absorption. Each enzyme and juice plays a crucial role in ensuring that we can extract the necessary nutrients from our food for energy and growth.
