the flux capacitor
Stomach
liver
i believe it is the stomach then the liver
the liver comes after
intestines: Digestive system lungs: Respiratory system
Urinary is the first that comes to mind...you drink something, then must excrete it via the kidneys/urine. But as I sit here and think about it, the pancreas comes to mind, which is part of the endocrine system as well as digestive... The pancreas is responsible for most of the enzymes that are used during digestion. So I guess it would go endocrine, digestive, then urinary.
It comes out as solid waste.
it helps because you urine comes from the uniaray sytem
It does not take a long time, the mouth is the first part of the digestive system.
mouth
mouth
the answer is ingestion.
