QUESTIONS AND ANSWERS SURE A+
✔✔What is the function of the mouth? - ✔✔mechanical breakdown of food; begins
chemical digestion of carbohydrates
✔✔What is the function of the pharynx? - ✔✔passageway for air and food
✔✔What is the function of the esophagus? - ✔✔to carry food, liquids, and saliva from
the mouth to the stomach
✔✔What is the function of the stomach? - ✔✔digest food
✔✔What is the function of the small intestine? - ✔✔digestion and absorption
✔✔What is the function of the large intestine? - ✔✔absorption of water
✔✔What is the function of the rectum? - ✔✔regulates elimination of feces
✔✔What is the function of the anus? - ✔✔wastes exit the body
✔✔What is the function of the liver? - ✔✔produce bile
, ✔✔What is the function of the gall bladder? - ✔✔stores bile
✔✔What is the function of the pancreas? - ✔✔Secretes inslin and glucagon hormones
and makes pancreatic juices
✔✔What is the function of the salivary glands? - ✔✔produce saliva, initiates breakdown
of carbohydrates
✔✔What are the functions of the digestive system? - ✔✔digestion, absorption,
elimination
✔✔Describe the mucosa - ✔✔Epithelium, connective tissue, smooth muscle
✔✔Describe the submucosa - ✔✔Loose connective tissue, blood vessels, lymphatic
vessels, nerves
✔✔Describe the muscular layer of the GI tract - ✔✔Smooth muscle fibers in circular and
longitudinal groups
✔✔Describe the serosa layer of the GI tract - ✔✔Epithelium, connective tissue
✔✔Differentiate between primary and permanent teeth - ✔✔There are 20 primary
(baby) teeth.
There are 32 secondary (permanent) teeth.
✔✔Describe the nervous systems role for digestion - ✔✔Parasympathetic impulses
increase activities of digestive system.
Sympathetic impulses inhibit certain digestive actions.
✔✔Describe the different types of motility and mixing within the digestive system -
✔✔Food is first mixed with saliva in the mouth and then is pushed down the esophagus
by peristalsis. Then it is mixed with gastric juice and pushed into the small and large
intestine where it is moved along toward the rectum by segmentation.
✔✔Describe peristalsis versus segmentation - ✔✔Peristalsis is muscle contractions in
the esophagus, segmentation is muscle contractions in the large and small intestine.
✔✔mechanical digestion - ✔✔Part of digestion that uses movement and muscles to
break down food
✔✔chemical digestion - ✔✔Process by which enzymes break down food into small
molecules that the body can use
