> 1. The Digestive Tract
>
>
> – Discuss the purpose and components of the digestive system.
>
> The Mechanical Aspect of Digestion
>
> – Specify the key mechanical processes involved with the digestion of a
> food item of your choice.
>
> The Chemical Aspect of Digestion
>
> – Differentiate the mechanical and chemical digestive processes and
> discuss the role of enzymes and other gastric fluids in digesting sugar,
> starch, fiber, fat, and protein.
>
> A Letter From Your Digestive Tract
>
> – Review the letter on page 92 of your textbook. Discuss the correlation

> disorders.

preview of the answer..

As explained by Smith & Morton (2011), the digestive process is critical in ensuring the survival of living organisms and supplying them with the required energy. This complex task is performed by a group of organs that include the mouth, stomach, esophagus, and intestines. The digestive process involves three main steps namely ingestion, digestion, and absorption. This analysis provides an extensive discussion on the purpose and components of the digestive system, establishes the mechanical processes involved in food digestion, and describes the function of enzymes and other gastric fluids in digesting sugar…
