How long is each part of the digestive system?
The digestive system — which can be up to 30 feet in length in adults — is usually divided into eight parts: the mouth, the esophagus, the stomach, the small intestine (or “small bowel”) and the large intestine (also called “large bowel” or “colon”) with the liver, pancreas, and gallbladder adding secretions to help …
Which animal has the longest digestive system?
