Final answer:
The pathway of food through the digestive system includes the mouth, throat, stomach, small intestine, large intestine, and anus. It involves processes like chewing, digestion, absorption, and elimination. For example, when eating a hamburger, the food goes through these stages before being eliminated as waste.
Step-by-step explanation:
The pathway of food as it travels through the digestive system can be described as follows:
- The process starts in the mouth where food is chewed and mixed with saliva.
- The food then travels down the throat or esophagus into the stomach.
- In the stomach, the food is broken down further by stomach acid and digestive enzymes.
- The partially digested food then enters the small intestine where nutrients are absorbed into the bloodstream.
- The remaining undigested food and waste material move into the large intestine where water is absorbed and the waste material is compacted into feces.
- Finally, the feces are stored in the rectum and eliminated through the anus.
For example, when you eat a hamburger, it is first chewed in the mouth and mixed with saliva. It then travels down the esophagus into the stomach where it is broken down by stomach acid and digestive enzymes. The nutrients are then absorbed in the small intestine, and the remaining waste material is eliminated through the large intestine and rectum.
