Question: 1 / 405

What are the functioning units of the liver called?

Hepatic lobules

The functioning units of the liver are called hepatic lobules. Each hepatic lobule is a hexagonal structure that is essential for the liver's functions, including the metabolism of nutrients, detoxification of substances, and the production of bile. Within each lobule, hepatocytes (the liver cells) are arranged in a way that facilitates the circulation of blood and the interaction with bile ducts. This structural design allows for effective processing of blood and nutrients as they pass through the liver.

The other terms listed refer to different aspects of liver anatomy: Glisson's capsule is the connective tissue that envelops the liver; liver sinusoids are the specialized capillaries found within the lobules that allow for the exchange of substances between the blood and liver cells; and falciparum lobules is not a recognized term in liver anatomy. Understanding the hepatic lobule's role is crucial for comprehending liver function and pathology.
