Stomach
After entering your stomach, the pie soon becomes unrecognizable. The stomach's wall, lined with three layers of powerful muscles, begins churning and mixing it into smaller and smaller pieces. Gastric juices, rich in acid and enzymes, pour out of glands that line your stomach. The acid and enzymes help break down food into a thick, creamy fluid called chyme.
Once the concoction is well mixed, waves of muscle contractions propel it through the pyloric valve and into the first section of your small intestine (duodenum). The pyloric valve releases less than an eighth of an ounce of chyme at a time. The rest is held back for more mixing.
