hepatic sinusoid
Wide thin-walled blood vessels in the liver. In mammals they have neither veinous or arterial markers. Every claim on this page comes from the Leumas anatomy graph and carries its source.
What the hepatic sinusoid is
Wide thin-walled blood vessels in the liver. In mammals they have neither veinous or arterial markers. The atlas records it as a tissue at the tissue scale in the human body.
Where the hepatic sinusoid is
It sits in the abdomen and trunk, within the cardiovascular, digestive and endocrine systems. Not positioned individually. Drawn inside the structure this dataset says contains it — the containment is asserted, the exact spot within it is not.
What the hepatic sinusoid connects to
The atlas records 13 typed relationships for it, across 7 kinds of connection. part of abdomen, abdominal segment of trunk and liver, and 3 more.
Supply and innervation
Venous drainage: hepatic portal venule.
Also called
Also recorded as liver hepatic sinusoids, liver sinusoid, liver sinusoidal blood vessel, sinusoid of liver, sinusoidal blood vessel of liver and vas capillare sinusoideum, and 2 more. Searching any of those names reaches this page.

Questions
Where is the hepatic sinusoid?
It sits in the abdomen and trunk, within the cardiovascular, digestive and endocrine systems. Not positioned individually. Drawn inside the structure this dataset says contains it — the containment is asserted, the exact spot within it is not.
What does the hepatic sinusoid connect to?
Part of: abdomen, abdominal segment of trunk, liver, liver lobule, trunk and vasculature of liver.
Is the hepatic sinusoid 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.
