Flashcards do conjunto (32)
- 1Give an example for each: ruminant, Pseudo-ruminant, monogastric, and hind-gut fermenter.ruminant -> deer
pseudo-ruminant -> horses
monogastric -> pigs
hind-gut fermenter -> rabbits - 2What are some functions of the mouth?digestion -> (breaking down food through chewing with teeth, while simultaneously mixing it with saliva which contains enzymes that start the chemical digestion of carbohydrates)
communication - 3What is the purpose of the secondary palate?to separate the nasal cavity from the oral cavity, allowing for simultaneous breathing and chewing
- 4—1 -> philtrum
2 ->papila incisiva
3 -> palatum duram
4-> palatum molle
5 ->arcus pallatoglossus
6 -> ostium intrapharyngeum - 5—
- 6define Thecodont what animal(s) are they found in?dentition in which the teeth are embedded in the deep sockets of the jaw bone, found in crocodiles
- 7define Acrodont what animal(s) are they found in?an anatomical placement of the teeth at the summit of the alveolar ridge of the jaw, without sockets, characteristic of bony fish.
- 8define Pleurodont what animal(s) are they found in?an animal having teeth fused with the inner surface of the alveolar ridge without sockets (found in reptiles)
- 9list the functions for each type of tooth: Incisors: Canines: Pre-molars: Molars:Incisors -> cut food
canines -> tear food
premolars -> crush it
molars -> grind it into smaller pieces for swallowing. - 10Name some functions of the tonguetasting food, moving food around the mouth to aid in chewing and swallowing, forming sounds for speech
- 11Where is the pharynx?in the middle of the neck, behind the nose, and above the esophagus and larynx
- 12What connects the pharynx to the crop in some species?esophagus
- 13—
- 14Does the esophagus pass through the diaphragm?yes
- 15Name some functions of the stomachcreates digestive juices, breaks down food, & holds food
- 16How many stomach(s) do cows have? (if they have multiple, what are the parts?)one stomach but four compartments
listed in order -> rumen, reticulum, omasum, abomasum - 17What is different about bird stomachs?it is two chambered: the first chamber is the proventriculus and the second is the gizzard
- 18Woah who do those belong to?Chondrichthyes and bony fish
- 19Do crocs and alligators have a gizzard?yes
- 20—
- 21—
- 22What are the 4 chambers of the rumen? (list in order)g
- 23—
- 24Compare ruminants and pseudo-ruminantsRuminant digestive system is found in animals that have four compartments in their stomach. Pseudo ruminant digestive system is found in animals that have three chambered stomachs or monogastric stomachs (think camels when thinking of pseudo ruminants)
- 25Why does the inside of the omasum have so many folds?for extra surface area to help increase absorption of food
- 26You can eat a rumen…. ew….. what is it called?tripe
- 27Name some functions of the intestines:absorb and breakdown nutrients, eliminates waste
- 28Describe the Relative Intestine Length for each, and list why they are that length: Herbivores: Carnivores:Herbivores:
Long intestines - To allow time for digestion of cellulose-rich plant material, which is difficult to break down
Carnivores:
Short intestines - meat is readily digested, carnivores need less intestinal length to absorb nutrients efficiently. - 29What is the function of the pancreas?produces digestive enzymes to help aid in breaking down food and can also produce hormones like insulin and glucagon to regulate blood sugar levels
- 30Who has a pancreas? who doesn't?Mammals, birds, reptiles and amphibians have one
fish don't have one - 31What is the function of a liver?filters all of the blood in the body and breaks down poisonous substances, such as alcohol and drug, can produce bile which helps aid in eliminating waste and digestion
- 32Who doesn’t have a gall bladder?lampreys, horses, & deer
