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 |
