Detailed explanation-1: -Venous blood rich in nutrients enters the liver from the hepatic portal venous system. The hepatic portal vein drains the digestive tract and efficiently transports metabolic building blocks (sugars and amino acids) directly to the liver, where they are reconstituted into more complex molecules.
Detailed explanation-2: -The hepatic portal vein carries 75% of the hepatic blood flow and hence is crucial. It is not a true vein as it does not conduct blood directly to the heart. It supplies veins with metabolic substrates. It also ensures that food ingested is processed by the liver first before entering the systemic circulation.
Detailed explanation-3: -The hepatic portal vein is an important and unique vein that receives blood from structures of the abdomen and transports it into the liver for filtration and processing.
Detailed explanation-4: -Answer and Explanation: The blood coming from the digestive organs is filtered by the liver before distributing it to the rest of the body. This is because the blood from these organs is rich in nutrients, alcohol, drugs, and potentially toxic substances that the liver needs to metabolize, neutralize, and detoxify.
