Can a fish bone be digested?

No, fish bones are not digestible by humans.

Here's why:

* Structure: Fish bones are made of calcium phosphate, which is a hard and rigid material. Unlike the bones of mammals, which are softer and more porous, fish bones have a much denser structure.

* Lack of Enzymes: Our digestive system doesn't have the enzymes necessary to break down the tough structure of fish bones.

* Risks: If swallowed, fish bones can lodge in the throat, esophagus, or stomach, causing discomfort, pain, and even potentially serious complications.

Important: If you happen to swallow a fish bone, it's best to consult with a medical professional for guidance. They can assess the situation and advise on the best course of action.
