Organs opening into the buccal cavity of pharynx (supposedly modified nephridia) of invertebrates. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the peptonephridium is

Organs opening into the buccal cavity of pharynx (supposedly modified nephridia) of invertebrates. The atlas records it as a organ at the organ scale in the human body.

Where the peptonephridium is

It sits within the digestive system. Not positioned individually. Drawn inside the structure this dataset says contains it — the containment is asserted, the exact spot within it is not.

What the peptonephridium connects to

The atlas records 3 typed relationships for it, across 2 kinds of connection. part of digestive system and esophagus.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the peptonephridium. Only a minority of structures carry those edges here, so an empty answer means nothing has been recorded — not that there is nothing to record.

Questions

Where is the peptonephridium?

It sits within the digestive system. Not positioned individually. Drawn inside the structure this dataset says contains it — the containment is asserted, the exact spot within it is not.

What does the peptonephridium connect to?

Part of: digestive system and esophagus.

Is the peptonephridium 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.
