Body system function: The urinary system is also known as the excretory system has a key organ that does a lot and it's the kidneys. The kidneys are like a filtration system that take out bad stuff from your bloodstream but keep the good ones in to keep you healthy. The urinary system helps you get rid of solid waste as well as fluid waste. The fluid is known as urine which is the product of the urinary system.

Organs: The organs of the urinary system are the kidneys, the ureters, the bladder, and the urethra. The kidneys help filter out all the bad stuff from your bloodstream but they also help you survive from dehydration. This is because when you haven't had water for a long time it will tell the kidneys and the kidneys would reabsorb all water that it can. You then lose less water from your body because the kidneys are preventing you from losing some water in your body. Then there's the ureters which help the urine from the kidneys travel to the bladder. The bladder holds your pee until you go to the restroom. Then what carries the urine from the bladder all the way out of your body is the urethra. The process is first the kidneys filter waste from your bloodstream and then the ureters take the urine from the kidneys. The ureters then carry the urine to the bladder where it stays until you go to the restroom. Lastly the urethra takes the urine out of your body and in the toilet.

One organs function: The kidneys are a big role in the urinary system because it helps you stay hydrated and it filters all the stuff your body doesn't need into a liquid called urine which goes to the bladder.

Interactions with other systems: The Urinary system interacts with the circulatory system because when the urinary system takes out the waste from your bloodstream and the waste goes through the urinary system. The waste that is taken out from your bloodstream is urea, uric acid, and water but some water is returned to the bloodstream. The urinary system also interacts with the endocrine system by monitoring the compound and fluid levels.

Analogy explanation: A sink water filter is like the Urinary system because the Urinary system filters your bloodstream so it doesn't have any waste your body has. Then the sink filter takes the water (the bloodstream) from the sink and cleans it just like the urinary system does for your body. Then when you need to go to the bathroom the waste is stored in the bladder and when you need to go you go to the bathroom. With the sink filter it has a container that's connected to the filtration system and all the waste from the water goes in the containers just like the wasted from you body is held in the bladder. Then when your ready to clean the sink filter you can just take the waste out like how you release the waste in your body by going to the bathroom.

Redesign: We could redesign the urinary system by making it less dirty. If the urinary system is less dirty then it will get less diseases and infections. If the Urinary system had less infections and diseases people wouldn't have to get surgery for it. We could also make it so the urinary system takes more waste out from your bloodstream so you won't get sick from it in your bloodstream.
