What brings dirty blood into the liver?

Hepatic artery
Hepatic portal vein
Inferior vena cava
Superior vena cava

The correct answer is: Hepatic portal vein

The correct answer is the Hepatic Portal Vein. The Hepatic Portal Vein is responsible for carrying blood that is rich in nutrients and also the products of digestion from the gastrointestinal tract to the liver. This includes blood with absorbed nutrients, as well as waste products that need to be processed by the liver. This mechanism allows the liver to regulate and process the levels of nutrients and other substances in the blood before it enters the systemic circulation. Options A, C, and D are not correct because they do not bring dirty blood into the liver. The Hepatic Artery (Option A) carries oxygenated blood to the liver, the Inferior Vena Cava (Option C) carries deoxygenated blood from the lower body towards the heart, and the Superior Vena Cava (Option D) carries deoxygenated blood from the upper body towards the heart.
