Propulsion moves food through the alimentary canal and includes both swallowing and peristalsis. Which is like, gulping (deliberately) and peristalsis (automatically) advances down to the GI tract.
Mechanical digestion is the physical process of preparing the food for chemical digestion and involves chewing, mixing, churning, and dissecting. Such as, once the food enters the mouth, you chew it up and mix it around while chewing.
Chemical digestion is a series of catabolic steps in which complex food molecules are broken down to their chemical building blocks by enzymes. This is when, food is broken down by enzymes.
Absorption is the passage of digested end products from the lumen of the GI tract through the mucosal cells into the blood
