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
