abstract：:An acinus is the principal secretion unit of an exocrine gland. This paper sets up a mathematical model of an acinus and examines the effect on the output of varying the operating parameters, both of the secretion mechanism and the fluid properties. Particular reference is made to acini of the pancreas. The question o...
