In human anatomy, the Kidneys are located in Abdominal Cavity. The left kidney is located at Vertebral level T12 to L3 and the right one lies slightly lower. The right kidney lies below the Diaphragm and posterior to liver.
As kidneys filter the blood, they remove the waste as urine which then passes from the kidney where it collects in the renal pelvis. It then moves to the ureters which send it to the urinary bladder and then through the urethra as it is passed out of the body in a process known as urination.
