Do jellyfish and humans have a similar digestive system?

Jellyfish and humans have very different digestive systems. Jellyfish have a gastrovascular cavity, which is a single opening that serves as both a mouth and an anus. Food enters the gastrovascular cavity and is then broken down by enzymes. The nutrients are then absorbed into the jellyfish's body walls.

Humans, on the other hand, have a much more complex digestive system. Food enters the mouth and is then broken down by teeth, saliva, and stomach acid. The food is then passed to the small intestine, where it is further broken down by enzymes from the pancreas and bile from the liver. The nutrients are then absorbed into the bloodstream through the villi, which are small finger-like projections on the walls of the small intestine. The remaining waste products are then passed to the large intestine, where they are eventually expelled from the body.

In summary, jellyfish and humans have very different digestive systems. Jellyfish have a simple gastrovascular cavity, while humans have a more complex system of organs and enzymes that break down food and absorb nutrients.
