Which organ is NOT directly supplied by the celiac trunk?

The celiac trunk is a major artery that branches from the abdominal aorta and supplies blood to several vital organs in the upper abdomen. It divides into three primary branches: the left gastric artery, the splenic artery, and the common hepatic artery. These branches are responsible for delivering blood to the stomach, liver, and spleen.

The kidneys, however, are not supplied by the celiac trunk. Instead, they receive blood from the renal arteries, which branch directly from the abdominal aorta below the celiac trunk. Since the kidneys have their own dedicated arteries, they are classified as not being directly supplied by the celiac trunk, making this the correct answer. Understanding the vascular supply and the specific arterial branches is essential for recognizing how different organs are interconnected within the circulatory system.
