What types of cells are found in the intestine related to hormone secretion?

In the intestine, K cells and L cells are crucial for hormone secretion. K cells, located primarily in the duodenum, secrete the hormone gastric inhibitory peptide (GIP), which plays a significant role in regulating gastric function and glucose metabolism. L cells, found in the ileum and colonic mucosa, secrete hormones such as glucagon-like peptide-1 (GLP-1) and peptide YY (PYY), both of which are involved in insulin secretion and appetite regulation.

These cell types are essential for maintaining homeostasis in the digestive system and influencing metabolic processes, demonstrating their importance in gastrointestinal hormone regulation. Understanding the contributions of K and L cells enhances knowledge of how the intestine communicates with other organs regarding hunger and energy balance.
