29
It breaks down various nutrients found in feed into molecules that can be used by the cells of the body
digestive system
30
Stages of the digestive process include:
- biting - chewing - swallowing and mixing of food - digestion and absorption of nutrients - excretion of waste
31
__________ is the chemical breakdown of complex food into simple nutrients and ultimately into molecules that are small enough to pass across the wall of the intestines
Digestion
32
The passage of molecule across the intestinal wall in to the blood or lymph system is called__________
Absorption
33
Animals such as cattle, sheep, horses, and rabbits, which depends entirely on plants for food
Herbivores
34
Other species, such as dogs and cats, which depend almost entirely on the flesh of other animals for food
Carnivores
35
Species as swine, poultry, and humans, which consume both flesh and plants
Omnivores
36
Animals can be divided into three group based on their digestive systems
- ruminants - monogastrics - hindgut
37
Sheep, goat, cattle, and deer are ________ animals. they have four stomachs instead of one.
ruminant
38
The four stomachs of ruminat
- rumen - reticulum - abomasum - omasum
39
- the largest of the ruminant stomach - contains millions of microbes, bacteria, and protozoa - lining composed of many papillae that aid in the absorption of nutrients - produces a large amount of methane gas, mainly methane and carbon dioxide
Rumen
40
Swine and poultry are ________ animals which means they have a single glandular stomach
monogastric
41
Horses, donkeys, and rabbits are examples of __________ fermenters
hindgut
42
- The tongue and lips are used to select food that animal intends to ingest
mouth
43
Food is chewed or physically broken down to smaller pieces by a process called ________-
mastication
44
Saliva provides:
- lubrication so the food may be swallowed - enzymes that breakdown the nutrients
45
Foods move down the esophagus to the stomach in a wave-like motion called __________
peristalsis
46
It is a tube-like tract that connects the pharynx to the stomach
esophagus
47
When the animals swallows, the ________ rises so that the _________ closes off the ________ thus preventing food from entering the air passageway
larynx, epiglottis, trachea
48
It is a storage chamber that holds food particles
non-ruminant stomach
49
Foods particles enter the rumen and bacteria start eating or digesting these particles. T or F.
F
50
Ruminants get their main source of protein from digesting the microbes that pass into the small intestine. T or F.
T
51
All ruminants are herbivores. T or F.

52
Microorganisms in the digestive system of ruminants synthesize some amino acids essential to the animal. T or F.
F
53
__________ and ________ is expelled by belching and, to a lesser extent, absorbed into the blood

66
- Molecules in the ________ are converted to compounds that animals need for tissue growth, nerve formation, enzyme synthesis, and many other functions - It excretes bile, which is stored in gallbladder
Liver
67
This is where bile is stored
gallbladder
68
It has properties that allow it to emulsify fats, increasing the efficiency at which they are digested
Bile

Poultry do not have teeth to physically break down their food. The glandular stomach of poultry is called _________-
Proventriculus
70
Before reaching the proventriculus, food is stored in an enlargement of the gullet, called the ________
crop
71
Feed passes from the ______ into the _________
gizzard, duodenum
72
- provides oxygen to the blood - excretes waste gases such as carbon dioxide - create noise via the voice box or the syrinx
respiratory system
73
The respiratory system includes;
- lungs - nostrils - nasal cavity - pharynx - larynx - trachea
74
________ are the external openings of the respiratory tract that lead to the _________
Nostrils, nasal cavity
75
Air and food pass through the _______, but not the same time
pharynx
76
The ________ controls breathing and prevents the inhalation of foreign objects into the lungs
Larynx
77
The _______ contains rings of cartilage that are rigid and prevent it from collapsing
trachea
78
The trachea enters the chest cavity as a single tube to the base of the heart where it divides into two branches called ___________
primary bronchi
79
Inside the lungs, the bronchi branch into smaller bronchi and finally into very small tubes called ________
bronchioles
80
The bronchioles open into alveolar ducts, which lead to the smallest portions of the respiratory system called ________
alveoli
81
It is diffused from the bloodstream into the alveoli so it can be exhaled out of the body
Oxygen
82
The primary function of the lungs is to _________
exchange gases with the atmosphere
83
Muscles of the diaphragm contract causing the thoracic cavity to enlarge and a vacuum to be created. The lungs to expand and air is drawn into them
Inhalation
84
