In human anatomy, the hepatic portal system is the system of veins comprising the hepatic portal vein and its tributaries. It is also called the portal venous system, although it is not the only example of a portal venous system, and splanchnic veins, which is not synonymous with hepatic portal system and is imprecise (as it means visceral veins and not necessarily the veins of the abdominal viscera).
Famous quotes containing the words portal and/or system:
“Some sepulcher, remote, alone,
Against whose portal she hath thrown,
In childhood, many an idle stone—
Some tomb from out whose sounding door
She ne’er shall force an echo more,
Thrilling to think, poor child of sin!
It was the dead who groaned within.”
—Edgar Allan Poe (1809–1849)
“I candidly confess that I have ever looked on Cuba as the most interesting addition which could ever be made to our system of States. The control which, with Florida, this island would give us over the Gulf of Mexico, and the countries and isthmus bordering on it, as well as all those whose waters flow into it, would fill up the measure of our political well-being.”
—Thomas Jefferson (1743–1826)
