Ninja Nerd - Circulatory System | Pancreas Circulation Model

Posterior View of the Pancreas

• The celiac trunk is a large vessel that comes off the abdominal aorta and splits into three decently sized vessels: the left gastric, splenic, and common hepatic arteries.
• The left renal artery and right renal artery branch off the abdominal aorta.
• The superior mesenteric artery is a large vessel that branches off the abdominal aorta and supplies a decent portion of the small intestine.

Anterior View of the Pancreas

• The splenic artery branches off the celiac trunk and supplies the spleen.
• The common hepatic artery bifurcates into the proper hepatic artery and the gastroduodenal artery.
• The gastroduodenal artery gives off a small branch called the gastroepiploic artery and then forms the superior pancreatic duodenal artery.
• The superior mesenteric artery has multiple branches, including the middle colic artery, ileocolic artery, and right colic artery, and supplies a decent portion of the small intestine.

Arteries and Veins

• The left and right adrenal arteries (also called the superior renal arteries) supply the adrenal glands.
• The superior mesenteric vein is an important vessel that picks up nutrients and blood from the small intestine and a small portion of the large intestine.
• The intestinal veins bring blood from the small intestine and a small portion of the large intestine.
• The left and right adrenal veins (also called the superior renal veins) drain blood from the adrenal glands.

Formation of the Hepatic Portal Vein

• The superior mesenteric vein, splenic vein, and inferior mesenteric vein combine to form the hepatic portal vein.
• The hepatic portal vein also receives blood from the left gastric vein.
• The hepatic portal vein is a major vessel that carries blood into the liver, where it is filtered within the liver lobules.

Posterior View of the Pancreas

• The celiac trunk arises from the abdominal aorta and branches into the left gastric, splenic, and common hepatic arteries.
• The left and right renal arteries branch off the abdominal aorta.
• The superior mesenteric artery branches off the abdominal aorta and supplies a portion of the small intestine.

• The left and right adrenal arteries (also known as the superior renal arteries) supply the adrenal glands.
• The superior mesenteric vein collects nutrients and blood from the small intestine and a portion of the large intestine.
• The intestinal veins bring blood from the small intestine and a portion of the large intestine.
• The left and right adrenal veins (also known as the superior renal veins) drain blood from the adrenal glands.

Formation of the Hepatic Portal Vein

• The superior mesenteric vein, splenic vein, and inferior mesenteric vein combine to form the hepatic portal vein.
• The left gastric vein also contributes to the formation of the hepatic portal vein.
• The hepatic portal vein carries blood into the liver, where it is filtered within the liver lobules.
