what type of digestion occurs in the mouth when chewing food
BOTH mechanical and Chemical. Chewing is mechanical, saliva is chemical
Where does peristalsis occur?
esophagus, stomach, small intestine, large intestine
humans get diarrhea when water is NOT absorbed by this structure
large intestine
Bile is a secretion that helps in the digestion of
lipids
Which process increases the surface area of food PRIOR to chemical digestion
mechanical digestion (like chewing)
Both mechanical and chemical digestion begin in the ______
mouth
What parts of the digestive system are digestive enzymes secreted
mouth stomach and small intestines (MSSi)
which structures release digestive secretions directly into the small intestines
pancreas and gall bladder
which activity occurs in the esphogus
peristalitis
From which structure are glucose and amino acids and other nutrients absorbed
small intestines
chemical digestion ends in the ____________
small intestines
Chewing food increases the surface area of food which helps to
speed up the process of chemical digestion
An acid necessary for enzyme action to occur is found within the
stomach
The initial hydrolysis of carbohydrates occurs in
the mouth
where is gastric juice (like urea and bile) produced
the stomach
what is the role of teeth in digestion
they break down food mechanically and increase surface area so enzymes can act
which substances are released into the small intestines and aid indigestion
bile, pancreatic juice, intestinal juice
what helps humans produce feces with low water content
large intestines
