capillary

Any of the smallest blood vessels connecting arterioles with venules. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the capillary is

Any of the smallest blood vessels connecting arterioles with venules. The atlas records it as a organ at the organ scale in the human body.

Where the capillary is

It sits within the cardiovascular system. Only the system is known. The position shown carries almost no spatial information.

What the capillary connects to

The atlas records 16 typed relationships for it, across 7 kinds of connection. part of vasculature.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the capillary. 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 blood capillary and capillary vessel. Searching any of those names reaches this page.

Questions

Where is the capillary?

It sits within the cardiovascular system. Only the system is known. The position shown carries almost no spatial information.

What does the capillary connect to?

Part of: vasculature.

Is the capillary 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.
