Digestive System A&P UPDATED
Questions and CORRECT Answers
What are the parts of the digestive system? - CORRECT ANSWER- mouth, esophagus,
stomach, small intestine, large intestine, accessory organs
What are the functions of the digestive system? - CORRECT ANSWER- - physical and
chemical digestion
- absorption
- elimination of undigestible components
- regulation of energy balance
- interface
What is a digestive enzyme? - CORRECT ANSWER- break down chemical bonds found in
nutrients giving individual nutrients for absorption
What are the important accessory organs? - CORRECT ANSWER- liver - important in
"assimilation"
pancreas - digestive --> enzymes that break down
teeth - helps w/ mechanical breakdown
salivary glands - helps create the "bolus"
Mouth - CORRECT ANSWER- teeth (break particles) receptors for temperature and
form/texture, salivary glands --> enzymes, (digestion)taste buds
esophagus - CORRECT ANSWER- mucous
stomach - CORRECT ANSWER- chemical digestion, differentiates between ruminants and
non-ruminants
small intestine - CORRECT ANSWER- chemical digestion & absorption of nutrients
large intestine - CORRECT ANSWER- fermentation of CHO and proteins
, accessory organs - CORRECT ANSWER- teeth, salivary glands, the liver synthesizes bile
(stored in the gall bladder), & pancreas
Steps of the process of nutrition - CORRECT ANSWER- 1. procurement - seeking of food
(eyes, nose, ears)
2. ingestion - takes the feed into their mouth/stomach
3. digestion - hydrochloric acid starts chemical digestion in the stomach followed by gastric
lipase and pepsin + some digestion happens in the small intestine; process of breaking down
large polymers into individual nutrients
4. absorption - nutrients are moved into the inside of the animal's body
5. assimilation - nutrients are activated into metabolites
6. metabolism - metabolites (already active nutrients) are used in chemical reactions at a
cellular level
7. excretion - getting rid of waste products
What do enterocytes do? - CORRECT ANSWER- absorb nutrients
How do you determine if an animal is a ruminant or a non-ruminant? - CORRECT
ANSWER- based on how their stomach is divided
ruminants - CORRECT ANSWER- polygastric
compartmentalized stomach
non-ruminants - CORRECT ANSWER- monogastric / simple stomach
What is the true stomach in a cow? - CORRECT ANSWER- abomasum
What does the true stomach release? - CORRECT ANSWER- hydrochloric acid and digestive
enzymes
what are the 4 compartments in ruminants? - CORRECT ANSWER- rumen, reticulum,
omasum, & abomasum
