left cardiac atrium

A cardiac atrium that is in the left side of the heart. It receives oxygenated blood from the pulmonary veins, In mammals this is pumped into the left ventricle, via the Mitral valve. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the left cardiac atrium is

A cardiac atrium that is in the left side of the heart. It receives oxygenated blood from the pulmonary veins, In mammals this is pumped into the left ventricle, via the Mitral valve. The atlas records it as a organ at the organ scale in the human body.

Where the left cardiac atrium is

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

What the left cardiac atrium connects to

Supply and innervation

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