How does human pee?

Answer 1

The kidneys filter the blood of impurities and this substance becomes urine (pee). The urine then travels along tubes called ureters which takes the urine from the kidneys to the urinary bladder. When the bladder fills up, the person will feel the need to pee. The urine then travels from the bladder along a tube called the urethra to the toilet.

Answer 2

It comes from extra fluids your body doesn't need. Your liver filters out what it needs, sending the extra down your ureters into your bladder. For a visual example, make tea out of grinds, not a bag. Fold a paper towel into a skinny strip. Fill a cup or beaker of some kind (clear is best) with the tea you have made. Don't put too much in there, only about an inch. Leave the grounds in it! Fold the paper towel in half. Stick one half into the beaker with the tea. Place that beaker on a couple of books. Take another beaker and place it below, with the other half of the paper towel angled down towards it. This may take a few days, but the result is that the paper towel has soaked up the tea and it drips into the lower beaker, leaving the tea grounds in the higher beaker. This is what your bladder does.

Thank you, science class. I never thought I would use this information.
