How does the food change in consistency and form?
- There is a change in the food's consistency and form whenever it reaches the process of digestive system. In the said body system, as the food enters the mouth, the teeth breaks down the food into smaller pieces in order to form bolus during the process of chewing. With the aid of moistened saliva for the ability of swallowing the food with ease, chemical food breakdown occurs. Saliva, on the other hand, contains an enzyme named amylase that begins to break down large starches into simple sugars and the likes. As enzymes alter the structure, the food is being chemically broken down into smaller pieces in the stomach while mixing those with digestive juices in order to break it down thoroughly as chyme. Meanwhile, the small intestine absorbs nutrients from the chyme then turns it into a semisolid fluid consistency. After the food breakdown journey, the food wastes are being converted into solid wastes and eliminate those from the body in the form of feces.
How could the body absorb nutrients from the foods we eat?
- The small intestine acts upon the absorption of most nutrients. The digested nutrients absorbed by the small intestines were being aided by the specialized cells to go into the bloodstream. Once successfully delivered, the nutrients will then move around the different kind of cells in the body and responds to the each system's concern by utilizing its protection factor.
