caecum

A pouch in the digestive tract that connects the ileum with the ascending colon of the large intestine. It is separated from the ileum by the ileocecal valve, and is the beginning of the large intestine. It is also separated from the colon by the cecocolic junction. Every claim on this page comes from the Leumas anatomy graph and carries its source.

Questions

Where is the caecum?

It sits within the digestive system. Positioned deliberately as part of this species body plan.

What does the caecum connect to?

Part of: colon, digestive tract and large intestine.

Is the caecum the same in other species?

Leumas holds the same relationship vocabulary for every species it carries, so where another dataset records this structure you can put the two side by side on /compare.
