The Urinary System

Function:

The function of the Urinary System is to get rid of liquid, soluble waste.

Organs:

    The organs that make up the Urinary System is the Kidney which filters the urine. Then the urine goes down the ureters which is a pipe, and then into the bladder, where it stores the urine, until it is released by a muscle called the Urethra.

Interactions w/ Other Systems:

     The Urinary System interacts with the Circulatory System by filtering blood that passes by the kidneys. When blood from the Circulatory System reaches the kidneys, the kidneys filter out harmful waste in the blood and add it in urine. The Urinary System also interacts with the Endocrine System. The Endocrine System works with the Urinary System by controlling the amount of urine that is released and produced. If you are dehydrated the Endocrine System will tell the Urinary System to not produce as much urine and if you drink a lot the Endocrine System will tell the Urinary System to produce more urine.

Explanation:

     I compared the Urinary System to factory liquid/hazardous waste disposal pipes that dump harmful waste into water sources such as rivers. The function of these disposal pipes is to remove waste produced by the factory. When the factory uses materials to make products, it creates some substance that is not necessary for the creation of the product. The factory takes that substance and puts it through pipes and eventually dumps it out. The function of the Urinary System is to dispose of used liquids and potentially harmful substances. When the Urinary System no longer needs the water or has too much it dumps it out through the bladder, similar to how a factory removes waste products it no longer needs.

Structure and Function:

      The organ that I chose for this section was the bladder. The bladder is rounded in shape, hollow, and connects to the ureters. The bladder is also rubbery and is rather big. This is because humans (should) drink a lot of fluids to keep them hydrated and healthy, and since they drink a lot of fluids, they need something to carry that. Since the bladder is rubbery, it allows a lot of urine to go inside of it and if the bladder fills up, it expands since it is rubbery. The bladder is also big so it should take a lot of fluids to make the bladder expand.
