Secretions Released into Small Intestine
The small intestine is the major site of digestion and absorption of nutrients in the human digestive system. Several secretions are released into the small intestine to facilitate digestion and absorption. The secretions are:
1. Pancreatic Juices:
The pancreas secretes pancreatic juice, which contains digestive enzymes such as amylase, lipase, and proteases. These enzymes help break down carbohydrates, fats, and proteins to their respective components, which can be absorbed by the small intestine.
2. Bile:
The liver produces bile, which is stored in the gallbladder and released into the small intestine when food enters it. Bile helps in the digestion and absorption of fats by emulsifying them into small droplets, which can be easily broken down by pancreatic enzymes.
3. Intestinal Juices:
The small intestine also secretes its own juices, which contain enzymes that break down carbohydrates, proteins, and fats. These enzymes include maltase, sucrase, lactase, peptidases, and lipase.
4. Other Secretions:
Apart from the above secretions, the small intestine also secretes mucus, which lubricates the walls of the small intestine and protects it from the harsh digestive enzymes. Additionally, the small intestine secretes hormones such as secretin and cholecystokinin, which regulate the secretion of pancreatic juice and bile.
Conclusion:
In conclusion, the secretions released into the small intestine are bile, pancreatic juice, intestinal juice, mucus, and hormones. These secretions work together to facilitate the digestion and absorption of nutrients from food.
