blood

A fluid that is composed of blood plasma and erythrocytes. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the blood is

A fluid that is composed of blood plasma and erythrocytes. The atlas records it as a tissue at the tissue scale in the human body.

Where the blood is

This dataset records no region or system for it. No positional evidence of any kind. Drawn outside the body so it can still be found and counted, never inside it.

What the blood connects to

The atlas records 11 typed relationships for it, across 8 kinds of connection. part of hematopoietic system and hemolymphoid system.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the blood. 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.

Also called

Also recorded as portion of blood, vertebrate blood and whole blood. Searching any of those names reaches this page.

What does the blood connect to?

Part of: hematopoietic system and hemolymphoid system.

Is the blood 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.
