Final answer:
The last organ food passes through before reaching the stomach is the large intestine.
Step-by-step explanation:
The correct answer is C) Large intestine.
Food passes through the digestive system in a specific order. After food leaves the stomach, it enters the small intestine where most of the digestion and absorption of nutrients occur. The small intestine is the longest part of the digestive tract and has three sections: the duodenum, jejunum, and ileum. Finally, food passes through the large intestine, which is responsible for absorbing water and electrolytes, and forming and eliminating waste in the form of stool.
