How many teeth are there in an adult human and what do they do? -
ANSWER>>There are thirty-two teeth in the human mouth. Together they work to

for biting; one pointed canine for tearing; two fairly flat pre-molars for grinding;
and three flat molars for crushing.
What is the specific function of the salivary gland in the process of digestion? -
ANSWER>>Food is mixed and moistened with saliva (from the salivary glands)
containing enzymes that begin the process of chemical digestion by breaking
down starches.
Where are taste buds located? - ANSWER>>Taste buds are found primarily on the
tongue but also on the surface of the mouth and the wall of the pharynx.
Describe the function of the tongue in the digestive process. - ANSWER>>The
tongue grips the food, constantly repositions it between the teeth and forms it
into a compact mass which is pushed back to the pharynx to begin the process of
swallowing.
What is a bolus? - ANSWER>>A bolus is the compact mass of food formed by the
combination of chewing by the teeth and repositioning by the tongue.
List the 3 parts of the pharynx. - ANSWER>>the nasopharynx, the oropharynx, and
the laryngopharynx.
Through what sections of the pharynx does air travel? Through what sections of
the pharynx does food travel? - ANSWER>>Air enters the nose, continues through
the nasopharynx, oropharynx and the laryngopharynx. Air then enters the trachea
on its way to the lungs. Food and liquid enter the mouth, continue through the
oropharynx and the laryngopharynx but then continue into the esophagus.
What prevents food from entering the lungs and why is this necessary? -
ANSWER>>Food is prevented from entering the larynx by the epiglottis, a flap of
elastic cartilage which covers the larynx when swallowing food or liquid.
