Duodenum. the entry of food into it is controlled by pyloric sphincter.
Explanation:
The first part of small intestine is called duodenum.

deudenum,
jejunum,
ileum.
Stomach has constrictions (sphincters) on both of its ends. Food entry from esophagus to stomach is controlled by Cardiac sphincter (lower esophageal sphincter) and entry of food from stomach to duodenum is controlled by Pyloric sphincter.
