Digestive Organs
This muscular tube carries food from your mouth to your stomach.
esophagus
Chewing food is an example of this type of digestion.
mechanical digestion
This is the sticky, bacteria-filled film that develops on your teeth.
plaque
This is the solid waste that remains after the digestive system has removed usable nutrients and water.
feces
A student brushes their teeth twice a day. This is one way to help maintain healthy teeth and gums. Name one other habit they should practice.
flossing daily
This organ stores bile produced by the liver.
gallbladder
This type of digestion uses chemicals and enzymes to break food down.
chemical digestion
This is the hardest material in the human body and protects the outside of your teeth.
enamel
This wavelike muscular movement pushes food through the digestive tract.
peristalsis
Someone has red, swollen, irritated gums. This condition is most likely called this.
gingivitis
This organ absorbs most nutrients from digested food and contains tiny structures called villi.
small intestine
This thick liquid is produced when partially digested food mixes with gastric juice in the stomach.
chyme
This is the part of the tooth that can be seen above the gum line.
crown
These tiny, fingerlike structures increase the surface area of the small intestine and help absorb nutrients.
villi
A student hasn't brushed their teeth regularly and develops persistent bad breath. What is the medical term for bad breath?
halitosis
This organ absorbs water and helps form waste before it leaves the body.
large intestine
These substances help speed up chemical reactions involved in digestion.
enzymes
This is hardened plaque that can irritate the gums.
calculus (tartar)
This is an open sore that can develop in the lining of the stomach or small intestine.
ulcer
A student eats a sandwich. Explain what happens to the food from the mouth → stomach → small intestine → large intestine.
This flap of tissue prevents food from entering the windpipe when you swallow.
epiglottis
Name both major processes involved in digestion.
mechanical digestion and chemical digestion
This advanced stage of gum disease can damage the tissues and structures supporting the teeth
periodontitis
Put these in the correct order: stomach → mouth → small intestine → esophagus.
mouth → esophagus → stomach → small intestine
A person eats a meal containing carbohydrates, proteins, and fats. Explain how mechanical and chemical digestion work together to break down the food and allow nutrients to be absorbed.
Mechanical digestion physically breaks food into smaller pieces, beginning with chewing. Chemical digestion uses substances such as enzymes and stomach acid to break food molecules down further. The small intestine completes much of the chemical digestion and absorbs nutrients through the villi.
