lymphatic vessel

A vessel that contains or conveys lymph, that originates as an interfibrillar or intercellular cleft or space in a tissue or organ, and that if small has no distinct walls or walls composed only of endothelial cells and if large resembles a vein in structure[BTO]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the lymphatic vessel is

A vessel that contains or conveys lymph, that originates as an interfibrillar or intercellular cleft or space in a tissue or organ, and that if small has no distinct walls or walls composed only of endothelial cells and if large resembles a vein in structure[BTO]. The atlas records it as a lymphatic at the organ scale in the human body.

Where the lymphatic vessel is

It sits within the cardiovascular and lymphatic & immune systems. Only the system is known. The position shown carries almost no spatial information.

What the lymphatic vessel connects to

The atlas records 24 typed relationships for it, across 6 kinds of connection. part of lymph vasculature and lymphatic part of lymphoid system.

Supply and innervation

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

Questions

Where is the lymphatic vessel?

It sits within the cardiovascular and lymphatic & immune systems. Only the system is known. The position shown carries almost no spatial information.

What does the lymphatic vessel connect to?

Part of: lymph vasculature and lymphatic part of lymphoid system.

Is the lymphatic vessel 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.
