I am Kidney Woman! I save every citizen in Gotham city by removing waste products from the blood and regulating the water and fluid levels!
Idiots like them make my job a lot harder. Salt in diets is something citizens all need. But if they eat too much salt, it can damage the body overtime!
More salt in their diet signals the brain to cause thirst. When the thirst center goes on alert because things are too salty, and the body needs to dilute more salt, that's when they start to feel thirsty. More water = more urine and more work for me to do!
Voiding is one of the ways your body gets rid of unwanted substances. Pee consists of wastes like ammonia, uric acid, creatinine, urea, etc. and of course salts.
Once I create the urine, it travels down the two ureters and into the bladder. From there it's stored until it is time for secretion. The urine travels down through the urethra, there are different sizes for genders, and out of the body.
Now, they are happy and homeostasis is maintained. I'm always waiting for the next time...I WILL NEVER FAIL! (as long as you take care of me)
