ELI5: If I take a whole bunch of solid foods and I blend them to liquid form, do I pee them out? If so, why?

If I wanted to blend a apple, banana, and milk together for a smoothie and I drink it, would I pee it out or poop it out and why? As well, would the body still absorb all nutrients the same way?

Pee comes from filtered blood out of your kidneys, into your bladder...

Poop actually comes from your intestines connected to your stomach and your mouth.

Humans are basically poop tubes. 

So basically, you’ll poop out undigested solids and waste, you’ll pee out both stuff that was removed from your blood and water soluble vitamins. Pee will sometimes smell like what you ate, but make no mistake, there’s no direct path from your mouth to your pee.

Blending it will give increased absorption as if you chewed it all really really well.
