:The followings are local hormones , except alzy Leukotrienes a Interleukin -2 .b Prostaglandins c Secretin

The correct answer is c. Secretin.<br /><br />Secretin is a hormone produced by the small intestine in response to the presence of acidic chyme entering the duodenum. It stimulates the pancreas to release bicarbonate-rich fluid, which helps neutralize the acid and provides an optimal pH for the action of digestive enzymes. Secretin also stimulates the liver to produce bile, which aids in the digestion and absorption of fats.<br /><br />On the other hand, leukotrienes, interleukin-2, and prostaglandins are all examples of local hormones. Local hormones are hormones that act locally, rather than being transported through the bloodstream to distant target tissues. They are produced by cells in response to specific stimuli and act on neighboring cells to regulate various physiological processes.
