mitral valve

An atrioventricular valve that is part of the outflow part of the left atrium. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the mitral valve is

An atrioventricular valve that is part of the outflow part of the left atrium. The atlas records it as a organ at the organ scale in the human body.

Where the mitral valve is

It sits in the thorax and trunk, within the cardiovascular system. Positioned deliberately as part of this species body plan.

What the mitral valve connects to

The atlas records 9 typed relationships for it, across 6 kinds of connection. part of outflow part of left atrium.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the mitral 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 left atrioventricular valve, valva atrioventricularis sinistra, bicuspid valve and valva mitralis. Searching any of those names reaches this page.

Questions

Where is the mitral valve?

It sits in the thorax and trunk, within the cardiovascular system. Positioned deliberately as part of this species body plan.

What does the mitral valve connect to?

Part of: outflow part of left atrium.

Is the mitral 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.
