How does your body filter blood?

The liver breaks down the toxins in your body because toxin is a poisonous substance. Then, the kidneys filter the toxins out of the blood. It gets to the nephron by the capillaries. The capillaries take the blood to the nephron (tiny filters that separate waste from useful things in the blood)

This is how a nephron works:

- blood plasma goes through walls of capillaries
- waste and plasma goes in nephron tubes and the useful things go back to the capillaries
- leads to renal veins which goes out of kidneys (the blood)
- goes into collecting duct to nephrons
- processed into urine

Everyday, the kidneys produce 2.5 pints of urine, from 45 gallons of blood they filter.
