immune system
Anatomical system that protects the body from foreign substances, cells, and tissues by producing the immune response and that includes especially the thymus, spleen, lymphoid tissue, lymphocytes including the B cells and T cells, and antibodies. Every claim on this page comes from the Leumas anatomy graph and carries its source.
What the immune system is
Anatomical system that protects the body from foreign substances, cells, and tissues by producing the immune response and that includes especially the thymus, spleen, lymphoid tissue, lymphocytes including the B cells and T cells, and antibodies. The atlas records it as a region at the system scale in the human body.
Where the immune system is
It sits within the lymphatic & immune system. Only the system is known. The position shown carries almost no spatial information.
What the immune system connects to
The atlas records 9 typed relationships for it, across 4 kinds of connection. a kind of material anatomical entity.
Supply and innervation
This dataset asserts no arterial supply, venous drainage or innervation for the immune system. 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.

Questions
Where is the immune system?
It sits within the lymphatic & immune system. Only the system is known. The position shown carries almost no spatial information.
What does the immune system connect to?
A kind of: material anatomical entity.
Is the immune system 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.
