    Choose the correct order of the digestive system.

    • Mouth,stomach, small intestine, large intestine, esophagus

    • Mouth, esophagus, stomach, small intestine, large intestine

    • Option 2

    Correct Answer
    A. Mouth, esophagus, stomach, small intestine, large intestine
    Explanation
    The digestive system starts with the mouth where food is broken down by chewing and mixed with saliva. From there, the food travels down the esophagus, a muscular tube that connects the mouth to the stomach. In the stomach, the food is further broken down by stomach acid and enzymes. Next, the partially digested food moves into the small intestine where nutrients are absorbed into the bloodstream. Finally, the remaining waste passes into the large intestine where water is absorbed and the waste is formed into feces before being eliminated from the body. Therefore, the correct order of the digestive system is mouth, esophagus, stomach, small intestine, and large intestine.
