Along the inferior surface of the liver are several structures that collectively resemble the letter H. The gallbladder and the round ligament of the liver form the vertical superior parts of the H; the inferior vena cava and the ligamentum venosum form the vertical inferior parts.

The gallbladder is a pear-shaped organ localized on the right side of the body, directly under the liver. This organ functions to store a digestive fluid called bile until it's needed for digestion.The round ligament of the liver (also called ligamentum teres hepatis) is a remnant of the fetal umbilical vein. This ligament is part of the coronary ligament of the liver.The ligamentum venosum (also called the hepatogastric ligament) is a deep cleft on the posterior surface of the liver.
