Human kidneys viewed from behind with spine removed
Human kidneys viewed from behind with spine removed

The renal arteries normally arise off the abdominal aorta and supply the kidneys with blood. The arterial supply of the kidneys is variable and there may be one or more renal arteries supplying each kidney. Due to the position of the aorta, the inferior vena cava and the kidneys in the body, the right renal artery is normally longer than the left renal artery. The right renal artery normally crosses posterior to the inferior vena cava. Position of kidneys, view from behind with spine removed. ...

The renal arteries carry a large portion of total blood flow to the kidneys. Up to a third of total cardiac output can pass through the renal arteries to be filtered by the kidneys.


Diseases of the renal arteries

Renal artery stenosis, or narrowing of one or both renal arteries will lead to hypertension as the affected kidneys release renin to increase blood pressure to preserve perfusion to the kidneys. Renal artery stenosis is the narrowing of the renal artery. ... Renin, also known as angiotensinogenase, is a circulating enzyme (EC 3. ...


Atherosclerosis can also affect the renal arteries and can lead to poor perfusion of the kidneys leading to reduced kidney function and, possibly, renal failure. Renal failure is the condition where the kidneys fail to function properly. ...

Dr. Koop - Renal artery stenosis (454 words)
Renal artery stenosis is caused when atheroembolic renal disease results in narrowing of the renal artery.
Renal artery stenosis often causes hypertension (high blood pressure) with no other signs of its presence, and it is usually discovered in investigation for the cause of hypertension that is difficult to control.
Renal artery stenosis is, in fact, among the most common causes of secondary (caused by another condition)  hypertension.
AllRefer Health - Renal Artery Stenosis (Fibromuscular Dysplasia (FMD), Occlusion - Renal Artery, Renal Artery ... (526 words)
Renal artery stenosis is a narrowing or blockage of the artery that supplies the kidney, caused by atherosclerosis, fibromuscular dysplasia of the renal artery wall, or scar formation in the artery.
Renal artery stenosis often causes hypertension with no other signs of its presence, and it is usually discovered in investigation for the cause of hypertension that is difficult to control.
Renal artery stenosis may cause chronic renal failure if it affects both renal arteries or if the hypertension associated with this condition is prolonged or severe.
