👉 Phrenicohepatic is a medical term that refers to the relationship between the brain, liver and gallbladder. The liver is an organ located in the upper right portion of the abdomen, while the gallbladder is a fluid-filled organ located below the liver. The brain is also involved in the process of digestion, but it is not directly connected to the liver or gallbladder. This relationship can be influenced by factors such as genetics, lifestyle choices and certain medications.
