What does the digestive system do?

Breaks down foods

1

Name the 4 food stages?

1. Food - before injestion
2. Bolus - Chewed up food mixed w/ saliva
3. Chyme - bolus mixed w/ stomach acid & further
4. Feces - digested food & bacteria

2

2 types of digestion

1. Mechanical Digestion - Physical impact on the food item
-chewing - muscle contractions of the stomach
2. Chemical Digestion - Breakdown via enzymes & chemical compounds - saliva - stomach acid -intestinal enzymes

3

Define Amalase

enzyme that begins to breakdown the starches

4

Central incisors

front flat teeth

5

Lateral Incisors

Cutting teeth sightly curved

6

Canine teeth

Holding & tearing food

7

Bicuspid Teeth

used for grinding up foods

8

Molars

Used for grinding foods

9

Nasopharyngeal cavity

where nasal and oral cavity meet

10

Pharynx

voice box

11

Larynx

vocal cords

12

Sublingual gland

saliva gland

13

Submandibular gland

saliva gland near your back teeth/mandible

14

Parotid gland

saliva gland near back of mouth, tube carries it into cheek.

15

Uvula

stimulates gag reflex prevents food from getting in nose

16

Epiglottis

under tongue prevents food from getting in trachea

17

esophagus

tube to stomach

18

Trachea

Ridged pathway to lungs

19

swollowing

voluntary or in voluntary muscle reaction

20

peristalsis

involuntary muscle contractions

21

Esophageal spincter

prevents back flow into esophagus
top valve of the stomach

22

Pyloric spincter

valve between stomach & intestines
bottom valve

23

Rugeuy

layers of stomach not a flat smooth surface

24

small intestine

full of digestive enzymes provided by the pancreas

25

Bile

material that comes from the pancreas and gail bladder

26

Name the 3 parts of the small intestine

1. Duodenum
2. Ileum
3. Jejunum

27

Duodenum

1st part of the small intestine
this is where the enzymes are added to chyme

28

Ileum & Jejunumm

remaining portions of the small intestines

29

Iliosecal valve

connects small and large intestines
