The first step to obtaining nutrition is ingestion, a process where food is taken in through the mouth and broken down by teeth and saliva.
Describe the process of ingestion and its role in the digestive system
Food is ingested through the mouth and broken down through mastication (chewing).
Food must be chewed in order to be swallowed and broken down by digestive enzymes.
While food is being chewed, saliva chemically processes the food to aid in swallowing.
Medications and harmful or inedible substances may be ingested as well.

The first step in this process is ingestion:
