Anything smaller than a certain size is eventually filtered out by your kidneys. They are essentially the spaghetti strainers of your blood with very tiny holes. Small enough that red blood cells don’t fit in them. This is why your pee isn’t red, although it can be. If it is, see a doctor.

Anything larger than that is broken down by enzymes from your liver.
