Quizplus · Accepted Answer

Urea is a waste product produced by the liver when it breaks down proteins. It is filtered out by the kidneys and can be found in the renal medulla. Urea creates a concentration gradient in the renal medulla, which helps to draw more water out of the tubule and into the bloodstream. This process is known as countercurrent exchange and is important for maintaining electrolyte and water balance in the body.
