THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -The renal arteries are part of the circulatory system. They carry large amounts of blood from the aorta (the heart’s main artery) to the kidneys. Approximately 1/2 cup of blood passes through your kidneys from the renal arteries every minute.

Detailed explanation-2: -Excerpt. The renal arteries are the only vascular supply to the kidneys. They arise from the lateral aspect of the abdominal aorta, typically at the level of the L1/L2 intervertebral disk, immediately inferior to the origin of the superior mesenteric artery.

Detailed explanation-3: -The kidneys receive unfiltered blood directly from the heart through the abdominal aorta which then branches to the left and right renal arteries. Filtered blood then returns by the left and right renal veins to the inferior vena cava and then the heart. Renal blood flow accounts for 20-25% of the cardiac output.
