A

Breaks bond using intestines,organs and microbes

24
Q

What are the 3 parts of the small intestine

A

Duodenum, jejunum, ileum

25
Q

Describe the duodenum

A

In the upper part of small intestine, neutralizes stomach acid and has low ph, enzymatic digestion to break everything down

26
Q

Describe the jejunum

A

at the second bend of small intestine, does digestion but Mainly absorbs

27
Q

Describe the ileum

A

At the last part of small intestine, does absorption and immune responses

28
Q

What are the 3 parts of the large intestine

A

Colon, cecum,rectum

29
Q

What does the colon do

A

Absorbs water and forms feces

30
Q

What does the cecum do

A

It’s the blind pouch has one way in and one way out, main digestion area for some species

31
Q

What does the rectum do

A

Connect the colon to the anus

The mix of water, salt,mucus, and enzymes

33
Q

What r the 3 main salivary glands

A

Parotid,submandibular, sublingual

35
Q

What does the pancreas do

A

Makes digestive enzymes

36
Q

What type of stomach do pigs have and what diet

37
Q

What is the diet and stomach of chickens

A

Omnivore and monogastric

38
Q

What is the order of chickens digestive tract

A

Esophagus,crop (food storage), proventriculus ( equivalent to the stomach acid digestion happens ) , gizzard or ventriclus( a muscular stomach and it grinds food) , duodenum,jejunum, ileum,2 cecas , large intestine,And cloaca.

39
Q

What does the gall bladder do in the chicken

A

Secreates bile to small intestine that comes from the liver

40

Esophagus,stomach, pyloric sphincter( a muscle and closes off but allows fluids to small intestine) ,jejunum,ileum, connects with large intestine at ILEOCECAL JUNCTION,colon, rectum,anus

42
Q

Is the cecum active in pigs and dogs

A

No

43
Q

A

Yes

48
Q

What is massive in the horse GI tract and what does it do

A

Cecum and it’s where the bulk of digestion happens

49

52
Q

How many chambers do ruminants have 4

A

The main compartment is the rumen, reticulum,omasum,and the abomasum( true stomach)

53
Q

What is the order of ruminant stomach

A

Esophagus,rumen, reticulum(honey comb pattern) , omasum, abomasum,pylorus

54
Q

What does papilla do in the rumen

A

It increases the surface area of the rumen to get the feed to interact with the tissue and microorganisms

55
Q

What is the reticular grove

A

For newborn animals that are suckling, it bypasses the esophageal groove to stimulate tissues to then get the milk straight to omasum and bypass the rumen

56
Q

How is the rumen studied

A

With fistulated cows, the cows gets an opening made and a plug is put to the rumen
