1

Functions of the gastrointestinal system

Intake food
Digest food
Absorption
Elimination of waste

2

Types of digestion

Mechanical
Chemical
Absorption

3

Mechanical digestion

Chewing

4

Chemical digestion

-Mouth with saliva
-Stomach and intestines with enzymes

5

Absorption

Final stage in digestion:
Nutrients transported through the lining of the intestines into the blood and lymph

6

Parts of mouth

Lips
Cheeks
Hard palate
Soft palate
Uvula
Tongue
Tonsils

7

Mastication

Chewing

8

Deglutination

Swallowing

9

Pharynx parts

Inner: longitudinal
Outer: constrictor

10

Pharynx purpose

Uses its skeletal muscles and peristalsis to push the food down into the esophagus

11

Peristalsis

Pushing mechanism

12

Esophagus

10 in, mucus lined tube that connects the pharynx with the stomach

13

Accessory organs

Tongue
Liver
Gallbladder
Pancreas
Appendix
Teeth
Salivary

14

Appendix

-Has no known purpose, might be immune related
-Connected to ascending colon

15

Types of teeth

Deciduous
Permanent
Third year molars

16

Salivary glands

Salivary/parotid
Submandibular
Sublingual

17

Liver functions

Production of bile
Produces glycogen
Storage of vitamins
Release bilirubin
Removes toxins from the blood
Manufacture blood proteins
Produce cholesterol

18

Gall bladder

-Located on inferior surface of the liver
-Collects bike

19

Bile

Digestive juice, consisting of water, bile salts, and bilirubin that emulsifies fat

20

Enzymes made by salivary glands

Amylase

21

Foods amylase acts upon

Starches

22

Enzymes made by the stomach

Pepsin
Lipase
Renin(only in kids)

23

The stomach's enzymes act upon...

Proteins and fats

24

Enzymes made by the pancreas

Lipase
Amylase
Trypsin

25

The pancreas' enzymes act upon...

Fats
Starches
Protein

26

Enzymes made by liver

Bile

27

Food that bile acts upon

Proteins
Fat

28

Enzymes made by small intestine

Lactase
Sucrase
Maltase
Peptidase

29

Food that the small intestine's enzymes act upon

Sugar
Protein

30

Deciduous teeth

Baby teeth that erupt around 6 months

31

Permanent teeth

Erupt between 6-12 and are done after adolescence

32

Third molars

"Wisdom teeth" that emerge around 17-25

33

Mumps

Inflammation of submandibular glands

34

Saliva

Mixture of mucus and serous fluid

35

Saliva function

-Bind food together
-Contain amylase
-Inhibit bacteria
-Make food slippery enough to swallow

36

Enzymes

Proteins found in digestive juices that act on food substances, causing them to break down into simpler compounds

37

Pancreas

Pink, retroperitoneal, triangular gland that produced enzymes
