The liver is composed of a left and right lobe. The gallbladder is located at the right lobe and stores the bile. Two distinctive sources bring blood to the liver: the hepatic artery, which brings blood coming from the heart, and the portal vein that brings blood from the intestines. Then the hepatic veins eliminate/drain that blood. If we look closer, the liver is composed, of lobules where we find blood vessels, canals and cords interposed by liver cells, hepatocytes, which act as exchange zones. The liver is a large, meaty organ that sits on the right side of the belly. Weighing about 3 pounds, the liver is reddish-brown in color and feels rubbery to the touch. The liver has 2 main sections (lobes). Both are made up of 8 segments. The segments are made up of a thousand small lobes (lobules). The lobules are connected to small ducts (tubes) that connect with larger ducts to ultimately form the common hepatic duct. The common hepatic duct transports bile made by the liver cells to the gallbladder and the first part of the small intestine (the duodenum). Bile is a clear yellow or orange fluid that helps digest food. Normally you can't feel the liver, because it's protected by the rib cage. The liver has two large sections, called the right and the left lobes. The gallbladder sits under the liver, along with parts of the pancreas and intestines. The liver and these organs work together to digest, absorb, and process food. The liver's main job is to filter the blood coming from the digestive tract, before passing it to the rest of the body. The liver also detoxifies chemicals and metabolizes drugs. As it does so, the liver secretes bile that ends up back in the intestines. The liver also makes proteins important for blood clotting and other functions.
