To achieve the goal of providing energy and nutrients to the body, six major functions take place in the digestive system:

• Ingestion.
• Secretion.
• Mixing and movement.
• Digestion.

Which vitamins are made by the bacteria in the large intestine?

The bicarbonate that the large intestine secretes helps to neutralize the increased acidity resulting from the formation of these fatty acids. These bacteria also produce large amounts of vitamins, especially vitamin K and biotin (a B vitamin), for absorption into the blood.

What triggers the release of secretin from the small intestine?

Regulation of Synthesis and Release Secretin is synthesized and secreted by S cells in the small intestine, and neurons in the brain. Secretin release is mainly stimulated by gastric acid delivered into the duodenal lumen. In addition, secretin is released by digested products of fat and protein.

How does the pancreas connect to the rest of the digestive system?

Pancreas: Your pancreas is located behind your stomach and is attached to both your gall bladder and your small intestines. Among other functions, the pancreas aids in digestion by producing digestive enzymes and secreting them into the duodenum (the first segment of the small intestine).

Can you live without a pancreas?
