How does the small intestine reduce blood sugar levels?

The small intestine reduces blood sugar levels primarily through the absorption of nutrients and the regulation of hormone release. When carbohydrates are digested, they are broken down into glucose, which is then absorbed into the bloodstream. In response to rising blood sugar levels, the pancreas releases insulin, facilitating the uptake of glucose by cells for energy or storage. Additionally, the small intestine secretes hormones like GLP-1, which enhance insulin secretion and lower blood sugar levels.
