Answer:
- Ingestion. 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.
- small intestine. The small intestine absorbs most digested food molecules, as well as water and minerals, and passes them on to other parts of the body for storage or further chemical change. Specialized cells help absorbed materials cross the intestinal lining into the bloodstream.
- about 30 feet. The alimentary canal is the long tube of organs — including the esophagus, stomach, and intestines — that runs from the mouth to the anus. An adult's digestive tract is about 30 feet (about 9 meters) long.
- The large intestine consists of the colon, rectum, and anal canal. The wall of the large intestine has the same types of tissue that are found in other parts of the digestive tract but there are some distinguishing characteristics.
- four compartments . Ruminant stomachs have four compartments: the rumen, the reticulum, the omasum and the abomasum. Rumen microbes ferment feed and produce volatile fatty acids, which is the cow's main energy source.
