We had to write and explantion piece about the Urinary System. This is mine:

The urinary tract system has many assets to it, being the Kidneys, Ureters, Bladder and Urethra. Your urine is full of different things that make it, like water, foods, urea, chemicals, and even some things that you have breathed, and been exposed to! Your urinary system sometimes comes up with some problems, like infections to the Kidneys, Bladder and Urethra. Sometimes, we need to hold onto our Urine for a while though, and this can lead to some bad things happening with your Bladder.

Have you ever wondered what your Urine may be made up of? Because your Urine is made up of many different things, and sometimes some things can even change the colour of your Urine from yellow to red! Your Urine is made up of many things, but it mostly made of water. Your urine is made with a sort of filter. The extra waste from your body, gets filtered through the kidneys, to make Urine. Then, at about every 10-15 seconds, your ureters, which are as thick as your middle finger, push very little bits of urine into your Bladder, which then, you let out through your Urethra.  The watse consists of water, Urea, foods, and other chemicals.  The waste, which is called Urea, is made when protein from meat is broken down. Some foods, like Beetroot, Blackberry,  and Rhubarb can turn your Urine colour pink or red!

There is many problems that may accure with the Urinary Tract System. Sometimes you could get a Bladder infection, which are called Cystirtis. You can get this infection, by bacteria reaching your Bladder. You could also get a Kidney infection, which is called Pyelonephritis. You can get this when large stones get stuck in in your Kidneys, which can cause a lot of pain.

Sometimes we all have that time when we just have to let it out, but what if it is the wrong time, and the wrong place? We’ve all had a situation like that,  so, what WILL happen if you hold onto your Urine for to long? Well, your Bladder can actually burst! Although this is very unlikely, some peoples Bladder have burst, which have lead to fatal, or painful endings. You really should be going about 8 times a day. If you don’t go, and your Bladder doesn’t burst, it can build up bacteria, which could lead to an infection.  

As you now know, the urinary system is very important. The foods and drinks you have are a very important thing to making your Urine, as much as what can cause problems with your urinary system, and what can happen if we hold on to much.
