The renal arteries normally arise off the side of abdominal aorta which is situated immediately below the superior mesenteric artery and supply blood to the kidneys. Each renal artery is directed across the crus of the diaphragm almost forming a right angle with the aorta. A large portion of the blood flow to the kidneys is provided by the renal arteries. The renal arteries can pass through a third of the total cardiac output to be filtered by the kidneys. The kidneys have a variable arterial and there can be one or more renal arteries supplying each kidney. They are located above the renal vein. A common renovascular anamoly is teo or more arteries to a single kidney (Supernumerary renal arteries) with an occurrence ranging from 25% to 40% of kidneys. A renal artery has a radius of 0.25 cm (approximately) and 0.26 at the root.
Review articles are the summary of current state of understanding on a particular research topic. They analyze or discuss research previously published by scientist and academicians rather than reporting novel research results.
Review article comes in the form of systematic reviews and literature reviews and are a form of secondary literature. Systematic reviews determine an objective list of criteria, and find all previously published original research papers that meet the criteria. They then compare the results presented in these papers. Literature reviews, by contrast, provide a summary of what the authors believe are the best and most relevant prior publications.
The concept of "review article" is separate from the concept of peer-reviewed literature. It is possible for a review to be peer-reviewed, and it is possible for a review to be non-peer-reviewed.
