The pyloric sphincter controls the exit of food from the stomach to the small intestines.
The correct option is a. true.
The movement of food from the stomach into the small intestine is controlled by the pyloric sphincter at its base.
The smooth muscle ring known as the pyloric sphincter, separates the small intestine from the stomach. It opens and shuts to regulate the movement of stomach fluids and partly digested food from the pylorus to the duodenum.
The pyloric sphincter starts to spasm in waves of peristalsis to push chyme into the pylorus once the stomach has finished its digesting function. The pyloric sphincter temporarily opens as each peristaltic wave reaches the pylorus to allow a little lump of chyme to enter into the duodenum.
