Hello,

Interesting questions! Let's take a closer look at the digestive system.

1. Start by imagining you are eating a carrot and describe the mechanical and chemical digestive processes that act on the carrot in the order of their occurrence in the body. In this description, identify which digestive processes are mechanical and which digestive processes are chemical.

Organs involved are the mouth, esophagus, stomach, small intestines and the large intestines. Each organ has a unique action and enzymes involved in mechanical and chemical digestion form the time the carrot or pizza enters the mouth. Carrots take longer to digest than pizza, and have different combinations of both chemical and mechanical processes e.g., takes longer and more effort to chew a carrot than a piece of pizza, etc. For example,

1). Mouth: The enzyme aiding digestion is the amylase in saliva. Mechanical digestion of all food (teeth chewing & grinding) chemical digestion of carbohydrates begins with amylase. Carrots involve more mechanical digestion in the mouth, as it involves more chewing and grinding than does ...

Solution Summary

By imagining you are eating a carrot, this solution describes the mechanical and chemical digestive processes that act on the carrot in the order of their occurrence in the body. In this description, it identifies which digestive processes are mechanical and which digestive processes are chemical. It then explains how this process would be different if you were describing the process of digesting a piece of greasy pizza.
