The right lobe is located to the right of the falciform ligament above, and the fissures of the gall bladder and vena cava below. Extending from the anterior edge, the quadrate lobe is a square-shaped lobe located in the anterior region between the fissure of the gall bladder on the right and the umbilical fissure on the left.

The liver serves as a filtering agent and gatekeeper for fluids in the body. It removes toxic substances from the blood and excess glucose from the body. The liver is the site for glycogen storage in the body. When glucose supplies are low in the body, the liver then produces more glucose through the conversion of amino acids. As the liver removes waste from the blood, it synthesizes urea, a waste product the body later excretes.
