The county jurisdiction includes the island of Santa Rosa south of Pensacola; it is not part of Santa Rosa County proper. Escambia County is part of the Pensacola-Ferry Pass-Brent Metropolitan Statistical Area.
It secretes juices containing enzymes that are capable of digesting all major types of food -- carbohydrates, fats and proteins. The pancreas is the first organ to begin digesting fats. It secretes pancreatic lipase, esterase and phospholipase, which break down chemically complex fats into simple, easy-to-absorb fats. Similarly, trypsin and carboxypolypeptidase break down proteins, and pancreatic amylase breaks down carbohydrates.
These stimuli cause an influx of intracytoplasmic calcium signaling the activation of phospholipases that then release arachidonic acid from its esterified position in membrane phospholipids. Arachidonic acid is acted upon by one of two major enzymes resulting in one of two classes of metabolites. Cyclooxygenases produce prostaglandins and thromboxane. 5-lipoxygenase produces leukotrienes. Prostaglandins and leukotrienes are locally active, short-lived mediators.
