lymph node
Any of the rounded masses of lymphoid tissue that are surrounded by a capsule of connective tissue, are distributed along the lymphatic vessels, and contain numerous lymphocytes which filter the flow of lymph. Every claim on this page comes from the Leumas anatomy graph and carries its source.
What the lymph node is
Any of the rounded masses of lymphoid tissue that are surrounded by a capsule of connective tissue, are distributed along the lymphatic vessels, and contain numerous lymphocytes which filter the flow of lymph. The atlas records it as a lymphatic at the organ scale in the human body.
Where the lymph node is
It sits within the lymphatic & immune system. Positioned deliberately as part of this species body plan.
What the lymph node connects to
The atlas records 57 typed relationships for it, across 10 kinds of connection. part of lymphoid system.
Supply and innervation
Arterial supply: lymph node artery. Venous drainage: lymph node vein.
Also called
Also recorded as lymph gland and nodus lymphaticus. Searching any of those names reaches this page.

Questions
Where is the lymph node?
It sits within the lymphatic & immune system. Positioned deliberately as part of this species body plan.
What does the lymph node connect to?
Part of: lymphoid system.
Is the lymph node 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.
