Question

What can be the consequences if, esophagus is directly attacjed with duodenum?

Answer 1

Food won't be able to mix with the basic enzymes for digestion. Ridges of muscle tissue called rugae line the stomach. The stomach muscles contract periodically, churning food to enhance digestion. The pyloric sphincter is a muscular valve that opens to allow food to pass from the stomach to the small intestine.
