Final answer:
The correct order of the digestive system through which food passes is Mouth, Stomach, Small intestine, and Large intestine, corresponding to option c) in the provided choices.
Step-by-step explanation:
The human digestive system, also known as the gastrointestinal (GI) tract, processes food in a specific sequence to effectively extract and absorb nutrients, and expel waste. The correct order of the digestive system parts as per the question would be c) Mouth, Stomach, Small intestine, Large intestine. This is because digestion begins in the mouth, where mechanical and chemical digestion starts with chewing and saliva. The food then moves down the esophagus to the stomach, where it is further broken down by stomach acids. Next, the food travels to the small intestine, where most of the digestion and nutrient absorption occurs. Finally, any undigested food moves into the large intestine, where water is absorbed, and the remaining waste is readied for expulsion from the body.
