Did you know in the next sixty seconds one point two liters blood would been filtered through your kidneys. the blood contains urea which is a waste product formed from the breakdown of excess protein in the body needs to get rid of the urea as it is toxic to the body if it pulls up.

The job of the kidneys is to filter out your urea along with the excess water and ions and excrete them from the body in the urine .so how does the kidneys do this well each kidney is actually made up of about a million microscopic portering units called nephrons as the blood flows into the renal artery it splits into smaller and smaller arteries these eventually become capillaries each capillary  pulls a bottle called Glomerulus the blood is now under very high pressure and the Glomerulus has little pools in it that allows the pools of the blood to be squeezed all the water through because I mean us it's finals and you're all get squeezed out of.

The water glucose amino acid ions and urea all  get squeezed out and recollected by a structure at the beginning of the nephron called Bowman's capsule and they are now referred to as the fulltrac the blood cells and lost proteins stay in the capillary because they are  to big to be squeezed out this process is called ultra filtration.

 the nephron is a quelled tube that moves through the kidneys that's the full trip pass anything with the boarding needs to keep it's taken back into the blood by a process called selective absorption. however the blood does not want the urea so it carries it through the nephron and eventually reach the collecting the the collecting duct takes waste on the area of the kidney called the pyramid which collects all the waste from all the nephrons.
Then it falls out of the kidney down the bladder where it is then  stored.
