Quizplus · Accepted Answer

The kidneys are a pair of organs located behind the abdominal cavity which filter plasma and form urine. They regulate body water balance (kidney failure often leads to edema formation). They also excrete water-soluble (but not fat-soluble) toxins from the body (e.g., keeping people from becoming uremic). They have other functions, as well.
