Digestive System
__
The Five Basic Processes
The five basic processes include..
❖ Mechanical Digestion
❖ Ingestion
❖ Chemical Digestion
❖ Absorption
❖ Excretion
Mechanical Digestion
● Begins in the mouth (Teeth)
○ The cheeks are crucial for keeping food in mouth when breaking down
○ The main components of mechanical digestion include the teeth, tongue, and
cheeks
The Esophagus (Muscular) Bolus
● This part of the process is also known as peristalsis
● Transfers food to the stomach
, The Stomach
● A form of mechanical digestion
● The liquid inside is called chyme, a liquid muscle with acid (HCl) and food
● The stomach is surrounded by mucus to prevent the acid from burning through
● The acid breaks down food in a chemical digestion form
The Small Intestine
● Consists of Duodenum (Chemical Digestion) ileum, and jejenum (Both help with
abortion)
