The renal cones are located within the medulla of the kidney, and the main tissue is the collecting ducts, which transport urine produced by the kidney to the renal calyces, then then to the renal pelvis, and finally into the ureter for discharge into the bladder. The kidney can be divided into two parts, the renal cortex and the renal medulla, the renal cones are located in the renal medulla, the renal cones are inverted triangles in the section, the bottom of the cones are towards the renal cortex, the tip of the vertebrae extends towards the renal sinus called the renal papilla, the main tissue of the vertebrae is the collecting ducts, and the renal papilla is the outlet of the urine produced. The urine produced by the kidneys passes through the renal papilla at the tip of the renal cone into the renal calyces, then into the renal calyces, and finally into the renal pelvis, where it passes through the ureter, the bladder, and the urethra and is then excreted from the body.
