The gross structure of the human digestive system limited to oesophagus,
stomach, small and large intestines, and rectum. The glands associated with
this system limited to the salivary glands and the pancreas.
O Salivary Glands: duct, secretions, amylase,
enter mouth starch -> maltose.
O Oesophagus: food from mouth -> stomach.
O Ad: Thick muscle wall
O Function: Transportation
O Stomach: muscular sac, inner layer ->
O Ad: Mucus to prevent stomach from being digested by
it's own enzymes.
O Function: Store and digest food primarily (proteins)
O Small Intestine: long muscular tube
O Ad: walls made up of villi, microvilli
O Function: help food digestion, provide large surface
area for enzyme to work
O Ad: Secretary glands produce digestion enzyme in
O Function: Absorb digested material to re-enter the
O Large Intestine: water reasborbtion
O Secretion of glands. Small Gorillas Only Sing Idiotic
O Function: food can become drier and thicker to form
feces and be removed. Instrumental Rythms.
O Rectum: egestion
O Food temporarily stored here, before being

O Food/Water may carry pathogens into the
stomach/intestines via mouth.
O The production of stomach acid (kill
microorganisms), enzymes (break down
pathogens) and mucous prevents the entry
