Herivores eat plants
Carnivores eat meat
Labia lips

what are the functions of the gi tract prehnsion of food transpert of foodbreakdown of foodabsoption of foodcarries waste to be eliminated form the body
what are the structures of gi mouth, teeth, tongue, pharanyx, esophagus, stmach, intestines.
what are the accessory organs salivary glands, liver, pancreas
sheep goats horses have what kind that help them to pick up food Soft flexiable lips
cattle and hogs have shift and immobile lips
rats have so that they can chew through material without having to ingest it lips that meet behingd the inscisors
members of the camel family have allowing them to graze without digging up the roots upperlips that split
conical papillae cone-shaped finger-like projections found onthr inside of the lips of ruminants. Prevents food from escaping from the mouth.
oral cavity contains gums teeth and tongue
what is the palate it forms the roof of the mouth
hard palate rigid bony structure covered with mucous membranes that contains transverse ridges of thickend membrane
soft palate parition between mouth and the nasoharanyx that is composed of muscle and covered with mucous membranes.
cheeks formed by buccinator muscle(keeps food between the teeth while chewing) and the buccal pad
tongue keeps food between the teeth during chewing puts pressure on the hard palate to aid in the swallowing used for the food prehension, licking, grooming, lapping up fluid
lingual frenulum anchors underside of the tongue to floor of the mouth
papillae elevation on the sides and the upper surface of the tongue.
gingivae/ gingiva covers the surfaces of the maxilla and the mandible and forms a collar around each tooth very vascular
teeth number vary between species and diet
deciduous teeth functions to cut and grind food and to provide defenserabbits and rodents have only one set of teeth that grow throughout life
carnivoers have brachydont teeth
crown projects above gumline
neck located in gumline
root fixes the tooth in the socket(bony Alveoulus)
enamel encases the crown( hardest substance of body)
Cementum encases the root. Cementum is bonelike
dentin lise under the enamel and cementum and makes up the bulk of the tooth
Alveolar Bone is the bony structure that supports the teeth
pulp cavity inside the dentin and conatins the tooths nerve and blood supply
perodental ligament connects cementum to bone of the alveolus
periodontium peridontal ligament+ the connections in the cementum+ surrounding Alveolaer bone
herbivores have hypsodont teeth
incisors front teeth that are used for shearing and cutting grass. aslo defense
canines "fangs eyeteeth, wolf teeth, tusks," used to them prominent in carnivore. Used for defense
premolars and Molars "cheek teeth," grind food to a size that can be swallowed.
dental formulas indicates the number of each teeth on 1 side of the mouth ICPM
lingual surface of the teeth next to tongue
buccal surface of teeth next to the cheeck
labial surface of teeth next to the lips
occusal surface of teeth for chewing
Salivary glands paratid(next to the parietal bone), mandibular, sublingual, Zygomatic(only in dogs)
saliva serous fluid secreted by the salivary glands that funcions to dissolve or lubicated food, facilitate swallowing, and initiate digestion.
Pharynx passage way for air and food
Esophagus muscular tube from the pharaynx through the diaphragm to the stomach dilates as food passes through
voluntary swallowing passage of food from the mouth to the pharaynx. at this point the larynx is blocked by the epiglottis so food should olgy the right way the tounge helps
1st invoulntary swallowing reflex phase that passes the food from the esophagus to the stomach. respiration is surppressed as to keepfood from going into the trachea
2nd invoulntary swallowing muscles contract the food through the cardiac sphinctor into the stomach
peritoneum membranes that lines the abdominal cavity; holds viscera in place
omentum fold of pertioneum overlying organs, esp stomach. lace like in apperance
mesentary peritoneal fold that attaches the intestines to the dorsal
nonruminant simple stomached
Monogastric single chambered stomach located caudal to diaphragm on the left side of the body 3 main parts: fundus, body, pylorus
sphincter muscle muscles that are ring shaped that close an opening when they contract
cardiac sphincter located between the esophagus and stomach . food enters when it relaxes. sphincters thightens when digestion is taking place. prvents reflux.
pyloric sphincter located between the pylorus and the duodneum. contracts to revent stomach conents from escaping during digestion. relaxes to allow contents to leave stomach and continue to intestines.
layers of intestinal wall (from inner to outer) mucosa, submucosa, muscular externa, serosa
chyme smeifluid contents of stomach after digestionmoves through digestive tract via peristalsis
4 chambers of a ruminant stomach rumen, recticulum, omansum, abomasum1st 3 chambers ferment the food.
