Ninja Nerd - Circulatory System | Liver Circulation Model

Blood Vessels in the Liver

• The common hepatic artery branches into the proper hepatic artery.
• The proper hepatic artery has branches that supply blood to the liver.
• The hepatic portal vein receives blood from the superior mesenteric vein, inferior mesenteric vein, gastric veins, and splenic vein.
• The hepatic portal vein branches into smaller veins that supply blood to the liver lobules.
• The hepatic portal vein tributaries are the branches that supply blood to the liver lobules.

Liver Blood Flow

• Blood from the hepatic portal vein is processed in the liver lobules.
• After processing, the blood is drained into the hepatic veins.
• The hepatic veins are responsible for draining the liver lobules.
• The blood from the hepatic veins flows into the inferior vena cava.

Additional Structures

• The gallbladder is attached to the liver and has its own blood supply from the cystic artery.
• The cystic artery supplies the cells of the gallbladder.

Blood Vessels in the Liver

• The common hepatic artery branching gives rise to the proper hepatic artery, which then supplies blood to the liver.
• The hepatic portal vein receives blood from four major sources: superior mesenteric vein, inferior mesenteric vein, gastric veins, and splenic vein.
• The hepatic portal vein then branches into smaller veins that distribute blood to the liver lobules.
• The hepatic portal vein tributaries are the branches that supply blood to the liver lobules.

Liver Blood Flow

• The liver lobules process blood from the hepatic portal vein.
• After processing, the blood is drained into the hepatic veins.
• The hepatic veins are responsible for draining the liver lobules.
• The blood from the hepatic veins ultimately flows into the inferior vena cava.

Additional Structures

• The gallbladder is attached to the liver and has its own independent blood supply from the cystic artery.
• The cystic artery supplies oxygenated blood to the cells of the gallbladder.
