The unusual circulatory pattern involving the liver and digestive organs is referred to as a pulmonary circuit b glycogenic blood barrier c hepatic portal system d lymphatic circuit?

The correct answer is c. Hepatic portal system

The hepatic portal system is a unique circulatory pathway involving the liver and digestive organs. Unlike the systemic circulation, which carries blood from the heart to the rest of the body and back, the hepatic portal system focuses on the liver's involvement in processing nutrients absorbed from digestion.

Here's an overview of the hepatic portal system:

1. Origination: The hepatic portal system begins with the capillaries in the digestive organs, including the stomach, intestines, pancreas, and spleen.

2. Portal vein formation: These capillaries merge to form the portal vein, which is the primary vessel of the hepatic portal system.

3. Blood flow: The portal vein carries blood rich in nutrients, including glucose, amino acids, and vitamins, from the digestive organs towards the liver.

4. Liver processing: The liver receives the nutrient-rich blood and processes it. This involves various functions such as detoxification, nutrient metabolism, and storage.

5. Hepatic veins: Once processed by the liver, the blood exits through the hepatic veins.

6. Return to systemic circulation: The hepatic veins merge into the inferior vena cava, which carries the blood back to the heart, completing the hepatic portal circulation.

The hepatic portal system serves as a critical intermediary between the digestive organs and the liver. It ensures that the nutrients absorbed from digestion are first delivered to the liver for processing and regulation before entering the systemic circulation.
