1

Finger-like projections increase surface area for absorption in small intestines

Villi

2

A lump of chewed food that moves to stomach

Bolus

3

These hard structures help to mechanically digest food in the mouth

Teeth

4

Organ produces bile

Liver

5

An enzyme which breaks the subunits of DNA and RNA into a phosphate, sugar, and nitrogenous base

Nucleotidase

6

The inactive form of the enzyme trypsin

Trypsinogen

7

What gets broken down into amino acids in digestive system

Protein

8

Small, finger-like projection located at junction of small and large intestines, which is believed to store bacteria that are important to proper functioning of the digestive system

Appendix

9

Small capillary of lymphatic system, found in the villi, and absorb fat

Lacteal

10

An enzyme which works on the duodenum to digest maltose

Maltase

11

Contains HCl and pepsin

Gastric juice

12

What is carried out by enzymes in the digestive system

Chemical digestion

13

What gets digested into glycerol and fatty acids in digestive system

Fats

14

This substance lines the stomach to protect it from damage from the stomach contents

Mucus

15

This substance is broken down by bile

Fat

16

Bile works to BLANK fats, separating large drops into tiny droplets

Emulsify

17

The slurry of water and partially digested food that moves from the stomach into duodenum

Chime

18

What carries bile from gall bladder to duodenum

Common bile duct

19

Folds in the wall of the stomach

Rugae

20

This liquid is secreted into the mouth

Saliva

21

This regulated the amount of chyme which is passed from the stomach to duodenum

Pyloric sphincter

22

The tube connecting the mouth to stomach

Esophagus

23

This structure stores feces before it’s eliminated

Rectum

24

The esophagus and intestines move food along their lengths using rhythmic muscle contractions called

Peristalsis

25

A hormone, secreted by pancreas, which stimulates the liver to release stored glycogen in order to increase blood glucose levels

Glucagon

26

This structure is responsible for the absorption of water after the digestive process is complete

Large intestine

27

A hormone, secreted by pancreas, which stimulated the uptake of glucose from blood to cells

Insulin

28

A substance produced by liver used in digestion

Bile

29

Tiny finger-like projections on the villi which further increase the surface area of the small intestine

Microvilli

30

Large sac in which the digestion of protein begin

Stomach
