What is the source of blood in the hepatic portal system?
Blood passes from branches of the portal vein through cavities between “plates” of hepatocytes called sinusoids. Blood also flows from branches of the hepatic artery and mixes in the sinusoids to supply the hepatocytes with oxygen.
What major vessels take blood to hepatic portal vein?
