Two sphincters guard the opening and closing of the stomach and three guard the anus.
Explanation:
The sphincter that opens into the stomach is the cardiac sphincter and the one that opens into the small intestine from the stomach is the pyloric sphincter. The anal sphincters are internal sphincter, external sphincter and levator ani.
