Functions of the kidney
removal of urea
Waste products are produced by our cells. These include carbon dioxide from respiration and urea from the breakdown of excess amino acids in the liver.
The renal arteries take blood with waste products to the kidneys to be filtered. Renal veins then return the filtered blood to be circulated around the body.
Blood vessels take the blood through the kidneys where the waste products are removed into convoluted tubules
These tubules join together to form the ureter, which transports urine to the bladder where it is stored.

Nephron
-
The glomerulus filters blood and produces glomerular filtrate. This filtrate contains water, glucose, salts and urea
The Bowman's capsule collects the filtrate and it enters the tubules. All glucose is reabsorbed immediately into the blood capillaries.
As the rest of the filtrate travels through the tubules, water and salts needed by the body are reabsorbed into the blood capillaries.

The waste, consisting of excess water, excess salts and urea, is urine.
The collecting duct collects the urine, which is then transported in the ureter to the bladder.
