Digestion

Question 1

mechanical digestion

Answer 1

breaking food into smaller pieces

Question 2

chemical digestion

Answer 2

breaking nutrients into smaller molecules

Question 3

hydrolysis

Answer 3

splitting molecules by adding water - happens during chemical digestion

Question 4

enzymes

Answer 4

speeds up chemical digestion - hydrolyses

Question 5

anus

butt hole - end of digestive track

Question 6

alimentary canal

Answer 6

tube between mouth and anus

Question 7

accessory organs

Answer 7

liver, gallbladder, pancreas

Question 8

surface area

Answer 8

happens after mechanical digestion - makes easier to swallow and digest

Question 9

Answer 9

releases saliva during mechanical digestion - contains enzyme amylase

Question 10

amylase

breaks down starch into smaller carbohydrate molecules (monosaccharides and disaccharides) - found in saliva

Question 11

pharynx

Answer 11

throat, leads to windpipe and esophagus

Question 12

esophagus

Answer 12

between pharynx and stomach

Question 13

epiglottis

Answer 15

muscular contractions that push food through body

Question 16

gastric juice

Answer 16

released by stomach - made up of hydrochloric acid and proteases

Question 17

protease

Answer 17

protein digesting enzymes

Question 18

chyme

Answer 18

the mix of gastric juices and partially digested food

Question 19

small intestine

Answer 19

after stomach in digestion

Question 20

pyloric sphincter

Answer 20

gallbladder

Answer 23

stores bile to help with digestion

Question 24

pancreas

Answer 24

supplies a number of enzymes needed for digestion

Question 25

villi

Answer 25

live in small intestine - increase surface area for the absorption of the end products of digestions into the blood and lymph

Question 26

large intestine (colon)

Answer 26

undigested food moves here after small intestine - responsible for reabsorbing water that has entered the alimentary canal

Question 27

rectum

Answer 27

solid waste stored here before being expelled

Question 28
