Which hollow organ in the left upper quadrant receives food, begins breaking it down, and sends it to the small intestine?

Explanation:
The stomach is the hollow organ in the left upper quadrant that receives food and begins breaking it down. It does this through mechanical churning and mixing with gastric juices—acid and enzymes like pepsin—forming a semi-liquid chyme. From there, the pyloric sphincter releases chyme into the small intestine for further digestion. The spleen sits in the LUQ but isn’t involved in digestion, the liver is a solid organ primarily responsible for processing nutrients and bile production, and the pancreas supplies digestive enzymes to the small intestine but does not receive ingested food.
