The digestive processes are
ingestion, propulsion, mechanical digestion, chemical digestion, absorption, and defecation
.
What are the six processes of digestion?
The six major activities of the digestive system are
ingestion, propulsion, mechanical breakdown, chemical digestion, absorption, and elimination
. First, food is ingested, chewed, and swallowed. Next, muscular contractions propel it through the alimentary canal and physically break it down into tiny particles.
Can you name the three functions of the GI tract?
