Peristalsis is the term used to describe how muscle layers contract and expand in order to move food throughout the digestive system. From the mouth, the food goes through the esophagus, into the stomach, then through the small and large intestines until it finally comes out the rectum. During this process, the small intestine absorbs nutrients which are moved into the blood stream by way of “vili”, or small projections in the small intestines, which contain dedicated cells to assist in the process.

Explanation:

According to USDA, “natural” meat and animal farm products should not include synthetic pigments, unnatural flavorings, chemicals or other synthetic components, and they should be “minimally treated”. However, this label does not reveal how the animals were grown, what they were served if antibiotics or hormones were used, or other perspectives of production that purchasers might reasonably expect from something designated “natural.”
