Guts and Glory

The white sharks digestion system is similar to ours, accept here aren’t as nearly many organs. The food is torn and chewed up by the razor sharp teeth and is immediately swallowed. It travels through a short esophagus where it eventually goes into the stomach by the control of a sphincter. Once in the stomach, the rugae or folds in the lining expand, a shark can eat up to 10% of its body weight. The stomach has HCl which breaks down bones, and Mucus which protects the stomach lining from the HCl. Furthermore, the pancreas has a duct or tube that empty protein digesting enzymes which starts protein breakdown.

The White Shark has a ring valve intestine which the food enters once broken down by the stomach by another sphincter. This where all the food nutrients is absorbed. Then the food is expelled through the anus after  it is as absorbed as it can be.
