What is papilla in kidney?
Papilla. The renal papilla is the location where the renal pyramids in the medulla empty urine into the minor calyx in the kidney. Histologically it is marked by medullary collecting ducts converging to form a papillary duct to channel the fluid. Transitional epithelium begins to be seen.
How do you make a clay kidney?
Kidneys resemble beans in their shape, which is why we have a food called kidney beans. Take a ball of modeling clay and elongate it to an oval, then bend it slightly like a bean. Flatten it slightly on one side so it will lie flush against a mounting board. Repeat this for the other kidney.
