Now we will talk about that what is renal- renal means anything related to kidney so renal arteries are those arteries, which carries blood from the heart to kidney. These arteries extend to kidney and it purifies this blood. When the diameter of the renal artery is decreased then in this state arties cannot carry the right amount of blood and kidney stops its proper functioning that leads to kidney failure and causes many problems.
