Stomach

Real World Example

Picture trying to mix a salad in a small, cramped container where you need to shake everything up to ensure the dressing coats every leaf. Similarly, the stomach acts as a muscular baglike organ where food is vigorously mixed with digestive juices to break it down effectively. Just as the container's confines and your shaking motions ensure the salad is evenly coated, the stomach's muscular walls contract to thoroughly mix the food with enzymes and acids, facilitating digestion.
