The Urinary System

The urinary system is important to the human body. This system helps to regulate blood pressure and also by removing waste products from the blood. The first step in this process is when the blood enters through the renal artery, after that it enters the glomeruluos. This forces the blood in to the filtrate, this is also known as filtration.
Then it enters the nephrons which wastes are filtrated out from. Reabsorption plays the role of returning useful molecules back into the blood. Then it travels to the collecting duct. And lastly it is moved through the urethra. And the urine is removed.
