In the mouth - 32

Question 8

Parts of the teeth

Answer 8

Enamel
(outer hardest layer made up of calcium)

Dentine

Pulp Cavity

Cement

Question 9

Peristalsis

Answer 9

Peristalsis is a series of wave-like muscle contractions that move food through the digestive tract. It starts in the esophagus where strong wave-like motions of the smooth muscle move balls of swallowed food to the stomach.

Question 10

Where is water reabsorbed by the body

Answer 10

Large intestine

Question 11

Where is bile produced

Answer 11

Liver

Question 12

Where is bile stored

Answer 12

Gall blader

Question 13

Where is maltase produced

Answer 13

Small intestine

Question 14

Enzyme produced in mouth

Answer 14

Salivary amylase

Question 15

Acid produced in stomach

Answer 15

HCL

Question 16

Assimilation

Answer 16

Assimilation is the process by which absorbed food becomes a part of the body (and is also used in respiration). For example, amino acids are used to build new proteins.

Question 17

Microvilli Villi

Answer 17

These are finger-like projections that increase the surface area over which molecules are absorbed.

Question 18

Lacteal

Answer 18

These blood vessels in villi aid in the absorption of fats after digestion. Lacteals carry a fluid called lymph and fats are transported through this to blood vessels.

Question 19

Enzymes produced by liver

Answer 19

Amylase
Protease
Lipase

Question 20

Small intestine

First part -
Second part -

Answer 20

First part - Duodenum
Second part - ileum

Question 21

Villi are located

Answer 21

ileum - second part of small intestine

Question 22

Small intestine pH

Answer 22

Alkaline 8-9

Question 23

Which comes first small or large intestine

Answer 23

Small to large intestine

Question 24

Function of bile

Answer 24

Emulsifies fats (breaks from large droplets to small)
Eg of mechanical digestion

Question 25

Function of gall bladder

Answer 25

Stores bile till its released in duodenum

Question 26

Amalase

Question 27

Sensitivity

Answer 27

Ability to detect change/stimuli in the environment

Question 28

Enzyme breaking down proteins

Answer 28

protease

Question 29

proteins are broken into

Answer 29

amino acids

Question 30

Where does proteins break down into amino acids using protease

Answer 30

stomach, small intestine in duodenum

Question 31

Starch/carbohydrates are broken by which enzyme

Answer 31

amalase

Question 32

starch/carbohydrates are broken down into _ using amylase

Answer 32

glucose and simple sugars

Question 33

where is starch/carbohydrates are broken down into glucose and simple sugars using amylase

Answer 33

mouth, duodenum

Question 34

fats/lipids are broken down into _ using lipids in the pancreas

Answer 34

fatty acids/gycerol

Question 35

fats/lipids are broken down into fatty acids/glycerol using lipids in the

Answer 35

fats/lipids are broken down into _ using lipids in the pancreas

Question 36

fats/lipids are broken down into fatty acids/glycerol using __ in the pancreas

Answer 36

lipase

Question 37

Villi blood capillaries function

Answer 37

transport glucose and amino acids away from intestine

Question 38

villi lacteal function

Answer 38

runs through villi centre transport fatty acids and glycerol

Question 39

hcl in stomach function

Answer 39

breaks down food gives low pH for stomach enzymes to work

Question 40

bile function

Answer 40

neutralises the hcl coming from stomach alkaline breaks down large droplets of fat - emulsification

Question 41

villi are found

Answer 41

in ileum (2nd part small int)
