What is the significance of the hepatic portal system in the circulatory system?

(N/A) The hepatic portal system is a specialized vascular connection that exists between the digestive tract and the liver.
Its primary significance includes:
$1$. Nutrient Processing: Excess nutrients,such as glucose and amino acids absorbed from the digestive tract,are transported directly to the liver for storage and subsequent release when required by the body.
$2$. Detoxification: The liver processes substances absorbed from the gut,including the conversion of toxic ammonia into urea,which is then transported to the kidneys for excretion.
$3$. Metabolic Regulation: It ensures that the liver acts as a metabolic filter before the blood enters the systemic circulation.
