Final answer:
The liver is connected to the abdominal wall and diaphragm by several ligaments and to the lesser curvature of the stomach by the lesser omentum. It also has circulatory connections with other organs through the hepatic artery and portal vein.
Step-by-step explanation:
The liver is an essential organ that is primarily connected to the abdominal wall and diaphragm by the peritoneal folds known as ligaments, which include the falciform ligament, the coronary ligament, two lateral ligaments, and the ligamentum teres hepatis. The liver is positioned inferior to the diaphragm in the right upper quadrant of the abdominal cavity and is also tethered to the lesser curvature of the stomach by the lesser omentum. Additionally, the liver has connections with other organs through the circulatory system; it receives oxygenated blood from the aorta via the hepatic artery and nutrients and wastes through the portal vein from the gastrointestinal tract and spleen.
