what are the four stages your food is processed in the body?
digestion
breakdown of food so that we can use it in the body
mechanical and chemical
what are the two types of digestion?
enzymes
chemical digestion is possible because of _____
amylase
chemical enzyme found in our saliva in the mouth
major organ
organ of the digestive system that food passes through
accessory organ
an organ that aids in digestion but food does not pass through
epiglottis
covers windpipe when swallowing so food doesn't go down the wrong tube
NO
does digestion occur in the esophagus
peristalsis
