B. Birds have no gastric stomach
C. Birds have a storage area before the stomach
D. Birds have a ventriculus for grinding feed after the stomach

A

B. Birds have no gastric stomach

17
Q

Which of these is not a correct statement about avian GI tracts?

A. The pancreas of birds is very different based on its location
B. Crop function differs some among diet and species
C. The relatively small proventriculus is made up for by the ventriculus
D. The ventriculus acts to decrease particle size of digesta

A

A. The pancreas of birds is very different based on its location

18
Q

Hindgut fermenters ___________.

A. Can consume a forage-based diet because of their high fermentation capacity in the large intestine
B. Can have an ensacculated (sacculated) cecum and colon
C. Have a similar foregut and midgut to a pig or human
D. All of these

A

D. All of these

19
Q

Which of these is not an accurate comparison of GI tract compacity and fermentation?

A. Ruminants have much more relative foregut capacity than other GI tract types
B. All species types discussed have some possible large intestinal fermentation
C. Simple monogastrics usually have a similar capacity among the stomach, small intestine, and large intestine
D. Horses and cattle have similar relative capacity of the foregut, midgut, and hindgut

A

D. Horses and cattle have similar relative capacity of the foregut, midgut, and hindgut

20
Q

How are ruminants different from most other species?

A

They have a large fermentation vat before the small intestine

21
Q

(T/F) The GI tract uses and metabolizes many nutrients, in addition to digesting and absorbing them.

A

True

22
Q

Which of these is not an accurate comparison of horses with other livestock species?

A. Importance of hindgut fermentation to an individual horse depends on its diet
B. They can eat more fiber than pigs
C. They digest fiber better than cattle
D. They have faster passage rate than cattle
E. Although both have large intestinal fermentation, horses have more than pigs

A

C. They digest fiber better than cattle

23
Q

Who has the most minor contribution of fermentation to their diet in this list?

A. Grazing ewe
B. Broiler fed corn-soy diet
C. Gestating sow
D. Grazing mare

A

B. broiler fed corn-soy diet

24
Q

Why do microbes do fermentation in the GI tract?

A

To provide energy for themselves

25
Q

(T/F) Not all livestock species do fermentation in their large intestine.

A

False

26
Q

What is the lumen of the GI tract?

A

The cells lining the GI tract, that touch digesta

27
Q

How does the mouth begin digestion?

A

-Through salivary enzymes in some species
-Mechanical breakdown with teeth or beaks
-Wetting feed and allowing a bolus to form

28
Q

What dictates teeth or beak structure, location, or number?

A

Role in feed/food intake and mechanical digestion

29
Q

(T/F) Most livestock and pets have significant quantities of salivary amylase

A

False

30
Q

Which of these is not a role of saliva?
-Killing pathogens
-Nervous regulation
-Aiding in formation of a feed/food bolus
-Making it easier for nutrients to reach taste receptors
-Protection of teeth

A

nervous regulation

31
Q

Which is not true about the esophagus?
-It connects to the stomach at the cardiac sphincter in non-ruminants
-It is to the side of the trachea in throat of most species
- It delivers food from mouth to stomach
- It is a muscular tube

A

It is to the side of the trachea in throat of most species

32
Q

Which of these best describes the role of HCl secreted in the gastric stomach?

A

Immune defense by killing many microbes, activation of pepsin, and some initial breakdown of digesta

33
Q

How does the stomach protect itself from the chemicals it secretes?

A

H+ and Cl- ions are secretly separately

34
Q

How does the GI tract regulate its secretions?

A

Using signals that are delivered before food is consumed, while food is in the stomach, and while digesta is in the small intestine

35
Q

Which of these is not a reason zymogens are used by the GI tract?
-Zymogens can be activated in the GI tract lumen by other chemicals present
-To protect the gastric stomach, pancreas, and small intestine from protease action during synthesis and secretion
-Because the GI tract and accessory organs often make enzymes that could digest their own tissues without protection measures
-To protect cells from dissacharidases and amylase

A

To protect cells from dissacharidases and amylase

36
Q

Which of these is not an accurate similarly or difference among species?

A

All species use the same approach to decrease digesta particle size
