8. There are millions of ______in the kidney. They are responsible for removing urea from the blood.

9. Blood reaches the ______, where the narrow vessels create an area of relatively high pressure. This forces the fluid part of the blood through the walls of the ______capillaries. Blood cells and proteins are too large to pass through and remain in the blood, but the fluid passes through.

10. The filtered fluid, or filtrate, trickles along the ______, where much of the water, glucose, and salts are reabsorbed, ensuring the blood maintains its correct composition. The toxic urea is left in the fluid.

11. The remaining fluid then trickles into the collecting ducts and finally into the ureters. Now called urine, it passes down the ureters and drips into the ______.
