What is the primary role of somatostatin in the gastrointestinal tract?

Somatostatin plays a crucial role in the gastrointestinal tract primarily by inhibiting the secretion of several other hormones. It acts as a regulatory hormone that helps maintain balance in the digestive system. By suppressing the release of hormones such as gastrin, insulin, and glucagon, somatostatin helps to slow down gastrointestinal motility and reduce the secretion of digestive enzymes and acids. This inhibitory effect allows for better regulation of the digestive process, ensuring that digestion occurs efficiently and that the body does not become overwhelmed by excessive hormone levels which could disrupt normal physiological functions. Thus, the primary role of somatostatin is indeed to inhibit other hormone secretion in the gastrointestinal system.
