cardiac valve

A membranous fold of the heart that prevents reflux of fluid. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the cardiac valve is

A membranous fold of the heart that prevents reflux of fluid. The atlas records it as a organ at the organ scale in the human body.

Where the cardiac valve is

It sits in the thorax and trunk, within the cardiovascular 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 cardiac valve connects to

The atlas records 14 typed relationships for it, across 6 kinds of connection. part of heart.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the cardiac valve. 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.

Also called

Also recorded as heart valve, valve of heart, heart valves, stomodaeal valve and valvule. Searching any of those names reaches this page.

Questions

Where is the cardiac valve?

What does the cardiac valve connect to?

Part of: heart.

Is the cardiac valve 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.
