Male reference · HRA lung v1.3
HRA male lung surfaces (13 left, 14 right) are shown within Whole Body. Their segment labels are source terminology that has not been reviewed, so there is no explorable hierarchy yet.

Male reference · BodyParts3D 4.0
BodyParts3D liver pieces are shown within Whole Body. Nine pieces the source labels "hepatovenous segments" were reviewed only so they render as liver tissue rather than vein; they are not reviewed Couinaud segments, and no liver segment hierarchy exists yet.
Known limitations- Liver pieces are not Couinaud segments
- Source segment VIII is two pieces
- Segment IX and caudate lobe not reconciled
