what determines whether what you eat gets used, stored or pooped out by your body?

In: Biology

Different parts of your digestive tract break down the food into simpler nutrients, and then absorb them. Once absorbed those nutrients go into the blood stream and are then taken in by the cells that require them (for use or storage). Anything that isn’t absorbed (stuff your body can’t break down or use) comes out as poop. Poop is just ‘filler’ and whatever nutrients there were too much of in that batch to be absorbed by the time they pass through the relevant area of the tract.
