2 mouth (teeth, tongue, salivary glands), esophagus, stomach, small intestine, large intestine, liver, pancreas, gallbladder 1 set
3 two main groups of organs - those forming the alimentary canal and accessory digestive organs 1 set
4 mouth, pharynx (glottis (hole) and epiglottis (flap) that connects to trachea), esophagus, stomach, small intestine (duodenum*, jejunum, ileum), large intestine *stuff from pancreas and liver (by way of gall bladder) enters small intestine here 1 set
5 salivary glands mouth pharynx- swallow esophagus- transport gall bladder- stores and transports bile liver- makes bile, stores vitamins, destroys poison stomach- stores and churns food pancreas- reg blood sugar small intestine- completes digestion, absorbs nutrients large intestine- resorbs water, forms and stores feces rectum- stores and expels feces anus- opening for elimination of feces 1 set
6 stomach -> small intestine (duodeum, jugenum, illium) -> cecum -> colon (large intestine) 1 set
7 mouth - (physical mastication) & (chemical) salivary enzymes begin to break down sugars/starches. esophagus - peristalsis movements from mouth to stomach. stomach- coated by strong gastric acid. little break down takes place in the stomach. food + gastric acid = "chyme" small intestitine - bile, pancreatic enzymes, and other enzymes produced by the small intestine break down food. large intestine - water and electrolytes are pulled out of food. microbes (good bacteria) help in digestion process. rectum- end of the large intestine where solid waste is stored until leaving through the anus. 1 set
8 oral cavity, pharynx, esophagus, stomach, small intestine, large intestine, salivary glands, pancreas, liver, gallbladder. 1 set
9 mouth & esophagus: ingestion & digestion stomach & s. intestine: digestion & absorption l. intestine: absorption & elimination rectum: elimination 1 set
10 gastrointestinal system - consists of the digestive tracts also known as the alimentary canal 1 set
11 oral cavity > pharynx > esophagus > stomach > small intestine (liver, gallbladder, pancreas) > large intestine (appendix) > anus 1 set
12 - buccal (oral) cavity - salivary glands - pharynx - esophagus - gall bladder - liver - stomach - pancreas - small/large intestines - appendix - rectum - anus 1 set
13 -mouth: palatine and lingual tonsils, sse, ingestion, mechanical and chemical digestion (starch), propulsion -pharynx: sse, naso, oro, laryngo, not nasopharynx, propulsion -esophagus: sse, propulsion: peristalisis-movement of food, adventitia rather than serosa -stomach: oblique layer for grinding food, propulsion, stores food temp, mechanical/chemical digestion (protein), becomes chyme; has gastric pits/glands w/ parietal cells (hci)/chief cells (pepsinogen) -small intestine: propulsion, chemical digestion of food, absorption of nutrients -large intestine (colon): sce, propulsion, water reabsorption, defecation of feces, synthesis of vit k and b 1 set
14 -broken down: 1) mechanical: chewing 2) chemical: starches, saccharides, and amino acids -salivary glands: secrete fluid onto food as well as enzymes to break it down (chemical digestion begins) -pharynx: connects to esophagus; it receives sensation and triggers swallowing -esophagus: moves food to stomach (by parastalsis which forces food down the esophagus) -stomach: stores food, churns food, secretes hydrocholoric acid (breaks down proteins) and pepsin, produces chyme (food all mixed by stomach muscle and has a ph of 2) -small intestine: 3 parts which are duodenum, jejunum, and ileum; absorbs nutrients and water and puts into blood; more chemical breakdown and parastalsis -large intestine: reclaim more water and produce stool/waste -sphincters: regulate passage of food from one region to another 1) cardiac sphincter: backflow of food from stomach and if you have back up=heart burn or acid reflex 2) pyloric sphincter: regulates food from stomach to small intestine -liver: produces bile which contains bile salts (helps emulsify and digest) and bicarbonate(buffer so helps with the ph of chyme so it's not so acidic) -galbladder: stores bile until needed; bile duct connects it to small intestine -pancreas: exocrine (produces enzymes to chemically breakdown food in small intestine) and endocrine (produce hormones that regulate blood sugar 1 set
15 -teeth: 20 decidious teeth: 2/1/0/2, 32 permanent teeth: 2/1/2/3 incisor, canine, premolar, molar; mechanical digestion; starch digestion begins -salivary glands: parotid (amylase), submandibular (mucus and amylase), sublingual-cheek (mostly mucus), chemical digestion (starch) and produce bolus: compaction of food -liver: falciform ligament connect diaphragm and abdominal wall; produce and release bile (emulsifies fat) and store/convert/detoxify nutrients -gallbladder: storage for bile -pancreas: produces enzymes for digestion of all macromolecules, regulates blood glucose levels 1 set
16 alimentary canal (gastrointestinal tract, gi) accessory organs four layers of the gi tract 1 set
