Veins do not send blood to capillaries. They receive blood from capillaries.
Arteries send blood to capillaries, in this case, specifically, hepatic arterioles.
A vein that sends blood to the hepatic capillaries is the hepatic portal vein.
hepatic portal vein
hepatic portal vein.
hepatic portal system
the vessel that carries blood between the intestinal capillaries and the sinusoids of the liver.
the gastrosplenic vein joins the superior mesenteric vein and takes blood to the hepatic vein
The hepatic artery in the liver enters from the bottom and is much smaller in diameter than the aorta or the portal vein that it lies above. The hepatic vein exits the liver from the top, carries blood through the top portion of the liver, and is larger in diameter than the hepatic artery.
Gastrosplenic Vein joins the Superior Mesenteric Vein and takes blood to Hepatic Portal Vein and delivers blood to liver.
By definition arteries always carry blood away from the heart and veins carry it to the heart.Most arteries carry blood with the least amount of carbon dioxide. But there is an exception. The arteries that carry blood to the lungs is very high in carbon dioxide.
You have capillaries in the gastrointestinal tract. The capillaries unite to form the veins. You have again formation of the capillaries in the liver. Here the blood has to pass through the sinusoids to the central vein. The blood is accompanied by blood from the hepatic artery. The portal blood carry the nutrients. The hepatic artery carry the oxygen. The liver cells are metabolically active. They need both to perform the desired function. So you have very unique arrangement in the liver. So you have capillaries - veins - capillaries in portal circulation.
An artery carries blood to the liver, not a vein. The hepatic artery.Maybe you meant to ask which vein receives nutrient-rich blood from the small intestine. That would be the superior mesenteric vein. But it doesn't go to the liver.

The capillaries flow from an artery to a vein.
