Answer 1

The liver processes your blood, breaking any complex or dangerous compounds down so they’re easier to work with. In terms of “cleaning”, it tries to make things more water-soluble so they can be dissolved in urine. It’s also where most things get metabolised (like sugar and alcohol).

The kidneys filter your blood for impurities, so they can put those impurities into urine for your bladder to dispose of. They also regulate your blood for other things, like water and electrolytes. Really anything that can be “too high”.

Tldr: The liver chops things up. The kidneys filter things out.
