It is most likely the the stomach since the intestines do not break down food. The stomach is filled with extremely strong acids that are powerful enough to dissolve razor blades whole. The food drops into our stomachs and immediately breaks down. Then the stomach passes what is left through the Pyloric Sphincter (the wall passage between stomach and small intestine). The small intestine then absorbs all the nutrients through the villi (small hairlike cells on the inner intestine walls). Once the food reaches the large intestine, bile is added to the food, turning it into our stool, while absorbing liquids and salts from the product. Then the food leaves our bodies, only so we can obtain more.
