Detailed explanation-1: -Blood coming from the digestive organs flows through the portal vein to the liver, carrying nutrients, medication and also toxic substances. Once they reach the liver, these substances are processed, stored, altered, detoxified, and passed back into the blood or released in the bowel to be eliminated.

Detailed explanation-2: -Blood leaves the liver through the hepatic veins. This blood is a mixture of blood from the hepatic artery and from the portal vein. The hepatic veins carry blood to the inferior vena cava-the largest vein in the body-which then carries blood from the abdomen and lower parts of the body to the right side of the heart.

Detailed explanation-3: -The blood flows into the liver through the hepatic portal vein. It filters through the liver in a system of smaller and smaller veins. As blood passes over liver cells, these cells process nutrients in the blood. This processing makes products like proteins and sugars that your body can use.

Detailed explanation-4: -Blood travels through the liver. The liver filters (cleans) the blood, removing toxins and waste that eventually leave the body through urine and feces. The lobes also contain thousands of lobules (small lobes). These lobules connect with many bile ducts, tubes that transport bile from the liver to the small intestine.

Detailed explanation-5: -The liver’s blood supplies 75% of its blood comes in through the portal vein system. This is a network of blood vessels which transport blood through the intestine, stomach, the spleen and the pancreas, draining into the portal vein and then into the liver.
