special hamburger in about a minute, it acts like an instantaneous input of 325 g of food entering the stomach. In response, the stomach starts producing gastric liquids (acids), which are continuously excreted into the stomach at a rate of 12.0 mL/min as the hamburger is digested. The fluid also leaves the stomach to the small intestine at a flow rate of 12.0 mL/min, so the volume of liquid in the stomach stays constant at 1.15 L. The hamburger digestion rate constant is 1.33 hr-1.
