Answer: (C)

About 1100 - 1200 ml of blood (1/5 th of cardiac output) is filtered at the level of the glomerulus of both kidneys per minute. Humans possess 1 million nephrons per kidney. The glomerulus and renal tubules are the parts of nephrons. Collecting ducts start from the cortex and extend into the medulla.
