pericardium
The combination of pericardial sac (a double-walled sac containing the heart and the roots of the great vessels) plus fibrous pericardium. Every claim on this page comes from the Leumas anatomy graph and carries its source.
What the pericardium is

Where the pericardium is
It sits in the thorax and trunk, within the cardiovascular system. Positioned deliberately as part of this species body plan.
What the pericardium connects to
The atlas records 11 typed relationships for it, across 6 kinds of connection. part of heart plus pericardium.
Supply and innervation

Questions
Where is the pericardium?
It sits in the thorax and trunk, within the cardiovascular system. Positioned deliberately as part of this species body plan.
What does the pericardium connect to?
Part of: heart plus pericardium.
Is the pericardium 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.
