Vascular branch delivering arterial blood via the splenic artery to ___________?
Show answer Hide answer
Answer: A. Spleen
Explanation
The splenic artery provides arterial blood supply directly from the celiac trunk to the human spleen. This tortuous blood vessel is the largest branch of the celiac axis supplying oxygenated blood to splenic pulp. Adequate arterial perfusion is critical for the spleen to filter blood and execute immune surveillance functions. The spleen is an intraperitoneal organ located in the upper left quadrant of the human abdominal cavity. Venous blood leaving the spleen collects into the splenic vein, which eventually forms the hepatic portal vein. Splenic tissue plays a major role in destroying aged red blood cells and storing emergency platelets.
The pancreas receives its primary arterial blood supply from branches of the pancreaticoduodenal and splenic arteries. The stomach receives oxygenated blood primarily from the left and right gastric and gastroepiploic arterial networks. The heart is an independent muscular pump supplied with arterial blood directly by the left and right coronary arteries.
