25
food is acted upon chemical substances called ______________ that melt food
enzymes or bio catalyst
26
organs of digestion is divided into two
- alimentary organ - accessory organ
27
Alimentary organ - where digestion begins
Mouth/oral cavity
28
Alimentary Break down food to smaller pieces
Teeth
29
Alimentary mixes the food with saliva and aids in swallowing
Tongue
30
Alimentary forms the roof of the mouth
Palate
31
Alimentary secrete saliva that lubricates food
SALIVARY GLANDS
32
Alimentary Passage way for digestion in the back
Pharynx or throat
33
Alimentary - prevent food for entering trachea
Epiglottis
34
Alimentary -passes from pharynx to stomach
Esophagus
35
Alimentary Stores food and mixed food with yellow juice
Stomach
36
Folds in stomach is called
Rugae
37
Chyme is
Digested food
38
Organ of complete digestion and absorption also longest organ in digestive system
Small intestines
39
SMALL INTESTINE - considered as the organ of complete digestion and absorption longest organ of digestive system divide into THREE:
❑ Duodenum ❑ Jejunum ❑ Ileum
40
Called colon, fecal materials, absorb vitamims, reabsorb water
Large intestines
41
Warehouse for feces
Rectum
42
Anus
Exit
43
Food enter, get wet and chewed (epiglottis)
Bolus
44
During the act of swallowing, the bolus is transported by the esophagus into the stomach via wave-like contraction called
PERISTALSIS
45
Parotid gland Sublingual gland Submandibular gland
Salivary gland
46
Requirements of animals - inorganic material to maintain homeostasis (elements in the body)
Minerals
47

Vitamins
48
Nutritional Requirements of Animals
water, carbohydrates, proteins, lipids, minerals, and vitamins.
