Ch 5 Flashcards
passage of materials through the walls of the small intestine into the bloodstream
absorption
small building block of proteins, released when proteins are digested
amino acids
enzyme secreted by the pancreas and salivary glands to digest starch
amylase
terminal end or opening if the digestive tract to the outside of the body
anus
blind pouch hanging from the cecum
appendix
digestive juice made in the liver and stored in the gallbladder
bile
pigment released by the liver in bile
bilirubin
intestine
bowel
pointed, dog-like teeth next to the incisors
canine teeth
first part of the large intestine
cecum
portion of the large intestine consisting of the ascending, transverse, descending, and sigmoid segments
colon
carries bile from the liver and gallbladder to the duodenum
common bile duct
elimination of feces from the digestive tract through the anus
defecation
swallowing
deglultition
- primary material found in teeth
- it is covered by the enamel in the crown and a protective layer of cementum in the root
dentin
breakdown of complex foods to simpler forms
digestion
- first part of the small intestine
- measures 12 inches long
duodenum
- removal of materials from the body
- in the digestive system
- the removal of indigestible material as feces
elimination
- breaking up large fat globules into small globules
- increases the surface area that enzymes can use to digestive fat
emulsification
hard, outermost layer of a tooth
enamel
chemical that speeds up a reaction between substances
enzyme
tube connecting the throat to the stomach
esophagus
substances produced when fats are digested
fatty acids
- solid waste
- stool
feces
- small sac under the liver
- stores bile
gallbladder
simple sugar
glucose
starch
glucose is stored in the form of this in liver cells
glycogen
- substance produced in the stomach
- aids digestion
hydrochloric acid
third part of the small intestine
ileum
any one of four front teeth in the dental arch
incisor
- hormone produced by the endocrine cells of the pancreas
- it helps transport sugar into body cells
insulin
second part of the small intestine
jejunum
pancreatic enzyme necessary to digest fats
lipase
- large organ located in the RUQ of the abdomen
- it secretes bile
- it stores sugar, iron, and vitamins
- it produces blood proteins
- it destroys worn-out red blood cells
- it filters out toxins
liver
- ring of muscles between the esophagus and the stomach
- also called the cardiac sphincter
lower esophageal sphincter (LES)
chewing
mastication
three large, flat teeth at the back of the mouth, on either side of the dental arch
molar teeth
two teeth before the molars
premolar teeth
roof if the mouth
palate
lies anterior to the soft palate and is supported by the upper jawbone (maxilla)
hard palate
is the posterior fleshy part between the mouth and the throat
soft palate
- organ behind the stomach
- produces insulin and enzymes
pancreas
- small projections on the tongue
- taste buds are located within
papillae
salivary gland within the cheek, just anterior to the ear
parotid gland
rhythmic contractions of the tubular organs
peristalsis
- throat
- the common passageway for food from the mouth and for air from the nose
pharynx
large vein bringing blood to the liver from the intestines
portal vein
enzyme that digests protein
protease
- soft tissue within a tooth
- containing nerves and blood vessels
pulp
- ring of muscle at the end of the stomach, near the duodenum
- it is normally closed, but opens when a wave of peristalsis passes over it
pyloric sphincter
- distal region of the stomach
- opening to the duodenum
pylorus
last section of the large intestine, connect the end of the colon and the anus
rectum
ridges on the hard palate and the wall of the stomach
rugae
digestive juice produced by salivary glands
contains the enzyme amylase
saliva
begins the digestion of starch to sugar
amylase
parotid, sublingual, and submandibular glands
salivary glands
- lower s-shaped segment of the colon just before the rectum
- empties into the rectum
sigmoid colon
circular ring of muscle that constricts a passage or closes a natural opening
sphincter
muscular organ that recieves food from the esophagus
stomach
fat molecules composed of three parts fatty acids and one part glycerol
triglycerides
soft tissue hanging from the middle of the soft palate
uvula
microscopic projections in the wall of the intestine that absorb nutrients into the bloodstream
villi
an/o
anus
append/o
appendic/o
appendix
