sinoatrial valve
A valve at the opening of the sinus venosus into the primordial atrium[TFD,modified]. Every claim on this page comes from the Leumas anatomy graph and carries its source.
What the sinoatrial valve is
A valve at the opening of the sinus venosus into the primordial atrium[TFD,modified]. The atlas records it as a organ at the organ scale in the human body.
Where the sinoatrial valve is
It sits in the thorax and trunk, within the cardiovascular system. Not positioned individually, and containment is not asserted either. Drawn near structures of the same kind, which is a weak claim about location.
What the sinoatrial valve connects to
The atlas records 5 typed relationships for it, across 3 kinds of connection. a kind of cardiac valve and embryonic structure.
Supply and innervation
This dataset asserts no arterial supply, venous drainage or innervation for the sinoatrial 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 sinuatrial valve and sinoatrial valves. Searching any of those names reaches this page.

Questions
Where is the sinoatrial valve?
It sits in the thorax and trunk, within the cardiovascular system. Not positioned individually, and containment is not asserted either. Drawn near structures of the same kind, which is a weak claim about location.
What does the sinoatrial valve connect to?
A kind of: cardiac valve and embryonic structure.
Is the sinoatrial 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.
