Right lobe of the liverThe larger of the two main lobes. From the front it lies to the right of the falciform ligament.
Left lobe of the liverThe smaller main lobe. It tapers to a thin edge on the left side of the body.
Falciform ligamentA sickle-shaped fold from the liver to the front belly wall. From the front it marks off the right lobe from the left.
Round ligament (ligamentum teres)A cord in the free edge of the falciform ligament. It is what is left of the umbilical vein.
Coronary ligamentIt ties the liver's top to the diaphragm. Its two layers border the bare area.
Triangular ligamentsOne at each end of the coronary ligament. Its two layers meet there and tie the lobe to the diaphragm.
How this list was compiled: Every name and detail line was checked on 2026-09-30 against TeachMeAnatomy, The Liver, https://teachmeanatomy.info/abdomen/viscera/liver/; Gray, Anatomy of the Human Body, 20th edition, 1918 (public domain), the section on the liver, https://archive.org/details/anatomyofhumanbo00grayrich; Kenhub, Liver, https://www.kenhub.com/en/library/anatomy/liver; and Wikipedia, Liver, https://en.wikipedia.org/wiki/Liver.

The drawing: Drawn for this site on 2026-10-04 by script. The outlines of both views follow two public domain plates of Johannes Sobotta, Atlas and Text-book of Human Anatomy, 1906 (public domain; files from Wikimedia Commons): the liver from the front (https://commons.wikimedia.org/wiki/File:Sobo_1906_387.png) and the liver from below and behind (https://commons.wikimedia.org/wiki/File:Sobo_1906_389.png). The ligaments, vessels and ducts were checked against Henry Gray, Anatomy of the Human Body, 20th edition, 1918, figs. 1085 to 1087 (public domain). Own drawing in smooth curves through points read off the plates; no picture is embedded. Licence: own drawing; outlines after public domain plates
How it works
This liver diagram, no labels on it, is the front view: two lobes and the ligaments that anchor the organ. The underside, with the gallbladder and the two small lobes, is on the liver anatomy quiz.

Liver, no labels: the word bank
In alphabetical order: coronary ligament, falciform ligament, left lobe, right lobe, round ligament (ligamentum teres), triangular ligaments.
The liver without labeling: where each line ends
Two lines run into the body of the organ and end on the two lobes. A line from the top center comes down to the band between the lobes, the falciform ligament, and the cord hanging from the lower end of that band is the round ligament. The line at the upper left ends on the hatched band along the top edge, the coronary ligament. The last ends on the small triangle at the far end of that band, a triangular ligament.
The liver faces you, so the body's right is on the left of the page: the big lobe is the right lobe.
Drawn with no line: the stump of the inferior vena cava at the top, and the rounded bottom of the gallbladder under the right lobe.
The answer key writes two names short: Round lig. and Triangular.
Questions and answers
Where is the liver in the body?
In the right upper quadrant of the abdomen, just below the diaphragm, where the lower ribs on the right shield most of it. It reaches across the middle of the upper abdomen into the left side.
Is the liver an organ or a gland?
Both. It is the largest organ inside the abdomen and also the largest gland in the human body. As a gland it makes bile, which is why it counts as an accessory organ of digestion.
What are the ligaments of the liver?
The falciform, coronary and triangular ligaments are folds of peritoneum, the membrane that covers the liver, unlike a ligament in a joint. They hold the liver to the front abdominal wall and the diaphragm. The round ligament is a cord, not a fold.
Is there an answer key for a liver diagram not labeled?
Yes. The key is the same drawing with a name at the end of each of the six lines.
