Digestive System

Front 1

purpose of the digestive system

Back 1

to break down food into simple molecules that can be used by your cells

Front 2

simple molecule of proteins

Back 2

amino acids

Front 3

simple molecule of carbs

Back 3

monosaccarides

Front 4

simple molecules of fats

Back 4

fatty acids

Front 5

simple molecules provide

Back 5

energy

Front 6

function of the mouth:

Back 6

chew food to make smaller pieces

Front 7

incisors:

Back 7

sharp, used for cutting food

Front 8

cuspids/bicuspids

Back 8

grasping and tearing foods

Front 9

molars

Back 9

grinding food with large flat surfaces

Front 10

saliva's function:

Back 10

makes food easier to swallow and makes it easier to chew

Front 11

salivary amylase

Back 11

enzyme in saliva that initiates the breakdown of carbs into monosaccarides

Front 12

lysozyme

Back 12

enzyme in saliva that kills bacteria in your mouth

Front 13

3 salivary glands

Back 13

parotid, sublingual, and submandibular

Front 14

pepsin

Back 14

enzyme in the stomach that initiates breakdown of proteins to amino acids

Front 15

HCl

Back 15

hydrochloric acid, a solution in the stomach that provides working condition for pepsin and also kills some bacteria

Front 16

cardiac sphincter

Back 16

prevents stomach contents from moving back up the esophagus

Front 17

pyloric sphincter

Back 17

prevents chyme from reentering the stomach

Front 18

small intestine is...and has 3 parts...

Back 18

20 ft long 1 inch in diameter
duodenum, jejunum, ileum

Front 19

pancreatic amylase

Back 19

enzyme from pancreas that finishes breaking down partially digested carbs into monosaccarides

Front 20

trypsin

Back 20

enzyme made by pancreas, finishes breaking down partially digested proteins into amino acids

Front 21

lipase

Back 21

enzyme from the pancreas that breaks down fats into fatty acids

Front 22

sodium bicarbonate

Back 22

solution made by pancreas that nuetralizes Hydrochloric acid in the chyme

Front 23

Bile

Back 23

solution made by liver and changes fats into smaller pieces, stored in the gallbladder

Front 24

function of the jejunum and ileum

Back 24

absorb the simple molecules (nutrients) so that they can go to the cells in your body

Front 25

villi

Back 25

jejunum and ileum have this, it makes the surface area larger, so that there will be a greater absorbtion rate

Front 26

large intestine is...and has 3 parts..

Back 26

5 ft long, 2 1/2 inch diameter.
caecum, colon, rectum

Front 27

function of the large intestine

Back 27

to remove water from undigested materials, which will produce a concentrated waste called feces

Front 28

Bolus

Back 28

food once it comes into contact with saliva

Front 29

epiglottis

Back 29

closes and prevents bolus from entering the trachea while swallowing

Front 30

esophagus

Back 30

to get food from your mouth to your stomach

Front 31

order of digestive system

Back 31

mouth-esophagus-stomach-small intestine-large intestine

Front 32

chyme

Back 32

food once it has passed through the stomach
