After food reaches the stomach, it undergoes several processes:Mixing and Churning: The stomach muscles mix the food with stomach acids and enzymes, turning it into a semi-liquid mixture called chyme.Digestion: The stomach acid (hydrochloric acid) and enzymes (like pepsin) break down proteins into smaller peptides.Emptying into the Small Intestine: The pyloric sphincter at the bottom of the stomach gradually releases the chyme into the small intestine.The next step is for the chyme to move into the small intestine, where most of the nutrients will be absorbed into the bloodstream.
