Carter Mullins · Answer 1

a bile duct along with a portal venule and arteriole

Explanation:

Bile canaliculi are small ducts and are present between hepatocytes. These ducts collect the bile produced by the hepatocytes and pass it to bile ductules and then to the bile ducts. The bile ducts merge to form larger right and left hepatic ducts, which in turn merge and exit the liver as the common hepatic duct.

Hepatic sinusoids are the blood capillaries present between the rows of hepatocytes. These capillaries receive oxygenated blood from branches of the hepatic artery and nutrient-rich deoxygenated blood from branches of the hepatic portal vein.

A portal triad refers to a bile duct, branch of the hepatic artery, and branch of the hepatic vein. It is located at the three corners of the hexagonal hepatic lobules.
