Question
Answer
injestion   taking into the mouth  
digestion   breaking down process  
mechanical process   action that involves organ itself, like chewing  
chemical process   breaks down large food molecules into compounds that have smaller molecules, like acid breaking down food in stomach  
3 parts of digestive system   ailementary canal, GI tract, GI tube  
where digestive system starts   mouth  
where digestive system ends   anus  
29 ft   average length of digestive system  
20 ft   average length of small intestine  
how food is processed   digestion, absorption, metabolized  
4 quadrants   right upper, right lower, left upper, left lower  
used to loacal pain or symptoms related to digestive system organs   4 quadrants  
lumen   space inside digestive tract  
mucosa   most inner layer of digestive tract  
submucosa   inner layer of connective tissue, just outside of mucosa  
muscularis   two layers of smooth muscle that perform peristalsis  
serosa   attaches digestive tract to wall of abdominal cavity  
peristalsis   wave-like movements that mix food with digestive juices  
oral cavity   mouth  
mouth   where food enters digestive tract  
roof of mouth   hard palate, soft palate  
hard palate is made of   bone  
soft palate is made of   muscle and pharynx  
uvula   piece of soft palate hanging in throat  
this prevents any food and liquid from entering the nasal cavities above the mouth   uvula  
floor of mouth   tongue  
where are tastebuds   in papillae on tongue  
lingual frenulum   skin anchoring tongue in mouth  
3 parts of tooth   crown, neck, root  
crown   exposed portion of tooth  
neck   section between exposed and inset portion of tooth  
root   inset portion of tooth, in gum  
gingiva   gums  
enamel   hardest tissue in body  
what is only found on the crown portion of the tooth   enamel  
location of dentin and cementin   outer shell of tooth  
greatest portion of outer shell of tooth is composed of   dentin  
4 types of teeth   incisors, cuspids, bicuspids, tricuspids  
baby teeth   desiduous teeth  
number of baby deeth   set of 20  
number of adult teeth   set of 32  
produce saliva   salivary glands  
amouht of saliva excreted daily   1 L  
3 pairs of salivary glands   parotid, submandibular, sublingual  
largest salivary glands   parotid  
two types of salivary glands   serous, mucous  
type of gland secreting thin, watery solution made of enzymes   serous salivary gland  
type of gland secreting thick solution to help food move through digestive tract   mucous salivary gland  
two types of serous salivary glands   parotid, submandibular  
two types of mucous salivary glands   sublingual, submandibular  
this salivary gland is both serous and mucous   submandibular  
used in both respiratory and digestive systems   pharynx  
3 parts of pharynx   naso, oro, larengo  
upper part of pharynx behind nose   nasopharynx  
middle part of pharynx behind mouth   oropharynx  
lower part of pharynx behind larynx   larengopharynx  
main digestive organ   espohagus  
function of esophagus   passage way for food, pushes food towards stomach, connects pharynx to stomach  
where is stomach   upper left quadrant  
stomach   size of sausage when empty, expands when full, can push on diaphragm  
entryway of food to stomach   cardiac sphincter  
cardiac sphincter is also called   lower exophogeal sphincter  
function of cardia sphincter   keeps food from re-entering esophagus  
closes opening between end of stomach and start of small intestine   pyloric sphincter  
end of stomach   pyloris  
stomach wall is made of   smooth muscle and mucous membranes that secrete gastric juices and acid  
folds in empty stomach   rugae  
diameter of small intestine   2 cm  
division of small intestine   duodenum, jejunum, ileum  
first part of small intestine, where most of the digestion occurs   duodenum  
small instestine is made of   smooth muscle and mucous membrane for peristalsis  
function of intestinal glands   secrete inestinal juice for digestion and movement  
finger shaped projections from mucosa, absorb cargohydrates and proteins   villi  
largest gland in digestive system   liver  
main location of liver   right upper quadrant  
function of liver   secretes bile (EXOCRINE GLAND)  
function of bile   breaks down fats and emilinates cholesterol from body  
drains bile from liver   hepatic duct  
how bile enters and leaves gallbladder   cystic duct  
joins hepatic and cystic ducts and drains bile into duodenum   common bile duct  
concentrates and stores bile produced by the liver, located just under surface of liver   gallbladder  
exocrine gland and endocrine gland   pancreas  
type of pancreat gland that secretes pancreatic juices into pancreatic ducts   exocrine pancreatic gland  
type of pancreatic gland that secretes hormones into the blood   endocrine pancreatic gland  
where is the pancreas   behind the stomach  
pancreatic juice   most important digestive juice  
where does main pancreatic duct empty   duodenum  
cells not connected with pancreatic ducts, secrete hormones and insulin   pancreatic islet of langerhans  
parts of large intestine   cecum, colon, rectum  
parts of colon   ascending, transverse, descending, sigmoid  
external opening of the digestive tract   rectum  
beginning of large intestine   ileocecal valve  
large intestine is made of   smooth muscle and mucous membrane  
organ of elimination   large intestine  
this intestine moves slower than the other   large  
this happens when large intestine digests too fast   diarrhea  
this happens when large intestine digests too slowly   constipation  
average length of time for large intestine digestion process   3-5 days  
only this intestine has villi   small  
these stay contracted to keep anus closed   inner and outer anal sphincter  
involuntary anal muscle   inner anal sphincter  
voluntary anal muscle   outer anal sphincter  
worm like, blind tube just off cecum, plays no role in digestion but may aid in immune defense   veriform appendix  
serous membrane that lines abdominal cavity and covers organs in it   peritoneum  
this lines abdominal cavity   pareital peritoneum  
this covers each abdominal organ   visceral peritoneum  
extensions of peritoneum   mesentery and greater omentum  
largest extension of peritoneum, visceral extension, also called a lace apron, hangs from lower stomach and transverse colon over the intestines   greater omentum  
pareital extension of peritoneum that attaches small intestine to posterior abdominal wall   mesentery  
outside of peritoneum   retroperitoneum  
transforms food into substances that can be absorbed and used by cells   digestion  
digestive enzymes are found in   saliva, gastric juice, pancreatic juice, and intestinal juice  
process by which digested food moves from intestine into blood or lymph   absorption
