Consider: The mighty kidney

“Each kidney (bean-shaped organ) weighs about 5 ounces and contains approximately one million filtering units called nephrons. Each nephron is made of a glomerulus and a tubule. The glomerulus is a miniature filtering or sieving device while the tubule is a tiny tube like structure attached to the glomerulus.”

This is the closest I could find to an image of one nephron.
