The structure that suspends the liver from both the diaphragm and the anterior abdominal wall is the falciform ligament. This crescent-shaped peritoneal fold runs from the liver’s anterior surface to the inner aspect of the anterior abdominal wall at the level of the umbilicus. Along its inferior edge it contains the ligamentum teres hepatis, the remnant of the fetal umbilical vein. The upper edge of the falciform ligament blends with the coronary ligaments, the peritoneal reflections that attach the liver to the underside of the diaphragm, so this single ligament helps anchor the liver to both key surfaces. In short, the falciform ligament provides the anterior attachment to the abdominal wall and, through its continuity with the coronary ligaments, contributes to diaphragmatic support as well. The coronary ligaments themselves attach to the diaphragm, but do not extend to the anterior abdominal wall independently, and the round ligament/ligamentum teres is contained within the falciform ligament.
