Flashcards in Ruminant Digestive System Deck (32):
1

What animals have ruminant digestive systems?

Sheep
Cattle
Goats
Deer
Giraffes
Zebras

2

The 4 complex stomach structures in ruminants are:

Rumen
Reticulum
Omasum
Abomasum

3

1st part of the ruminant system
actions

Mouth - teeth and lips hold food and chew
saliva moistens food

4

2nd part of the ruminant system and actions

Esophagus - through which food goes to the stomach

5

3rd part of the ruminant system

Rumen - 1st compartment of the stomach

6

Function of the Rumen

large fermentation vat with bacteria, protozoa, and certain fungi to break down roughages

7

Rumen capacity in cows and sheep

Cows - 40 gallons
Sheep - 5 gallons

8

What does the Rumen digest and with what?

Uses micro- organisms
Digests cellulose, synthesizes amino acids, and B - complex vitamins

9

How do you identify the Rumen?

Lined with carpet - like papillae

10

4th part of the ruminant system

Reticulum - 2nd compartment of the stomach

11

Reticulum's function

Acts with Rumen in mixing activity and provides more storage for ferments, screens for foreign objects from digestive system

12

How to identify the Reticulum?

Has small compartments that look like "honey comb"

13

Reticulum's capacity

Cow - 2 gallons
Sheep - 2 quarts

14

5th part of the ruminant digestive system

Omasum - 3rd compartment of the stomach

15

Omasum's function

Aids in grinding action of food, moves 60-70% of water before abomasum

16

Omasum's nickname

Manyplies

17

How to identify the Omasum

Round and muscular with many folds

18

Omasum's capacity

Cow - 4 gallons
Sheep - 1 quart

19

6th part of the ruminant digestive system

Abomasum - 4th compartment of stomach

20

Abomasum's function and uses what

Where most digestion takes place - contents very liquid
has digestive enzymes: pepsin, rennin, bile
breaks down proteins and adds moisture

21

Abomasum's capacity

Cow - 4 gallons
Sheep - 3 quarts

22

7th part of the ruminant digestive system

Small intestine

23

How to identify the Small Intestine

Small in diameter, long in length

24

Function of the Small Intestine

Splits food into molecules and absorbs nutrients

25

Capacity of the Small Intestine

Cow 15 gallons; 130 feet
Sheep 2 gallons; 80 feet

26

8th part of the ruminant digestive system

Large Intestine

27

How to identify the Large Intestine

Large in diameter, small in length

28

Function of the Large Intestine

Absorbs water and forms indigestible wastes to solids - prepared for excretion

29

Capacity of the Large Intestine

Cow 10 gallons
Sheep 6 quarts

30

How do ruminants eat?

They eat fast and then regurgitate feed (cud) -done many times

31

Salivary glands functions

Secrete saliva, moistens food and mixes with food material to aid in swallowing

32

Pharynx

Funnels food into esophagus, preventing food materia from entering lungs
