Blood enters the kidney through the renal artery. Then ...
... the blood is filtered.
After the blood is filtered in the kidney ...
... water, nutrients, and chemicals travel through a nephron.
In the nephron ...
...cells absorb specific amounts of chemicals and water back into the blood.
After absorption ...
... excess water and chemicals go into the renal pelvis, through the ureter, and into the bladder.
The final step in the kidneys ...
...cleaned blood leaves through the renal vein and travels back to the heart.
