CORRECT ANSWERS
constipation (con-stip-ay-shun) - -ANSWER--When the intestines get blocked up.
fibre (feye-ber) - -ANSWER--Substance found in food which cannot be used by the
body. It helps to keep our intestines clean.
nutrition information (new-trish-un) - -ANSWER--Information label found on a food
packet to tell you what is in the food.
nutrients (new-tree-ents) - -ANSWER--Substances needed in the diet to provide raw
materials.
raw materials - -ANSWER--Substances used to make other substances out of.
solvent - -ANSWER--A liquid that can dissolve other substances to form solutions.
solute - -ANSWER--the minor (or smaller part) of a solution, this is generally the name
given for the thing that has been dissolved.
,starch - -ANSWER--Type of insoluble carbohydrate found in plants.
water - -ANSWER--A compound made of hydrogen and oxygen which the body uses as
a solvent.
balanced diet - -ANSWER--Eating a wide variety of foods to give us all the things that
we need.
carbohydrate (car-bO-high-drate) - -ANSWER--Substance found in food that is used for
energy.
chemical energy - -ANSWER--Energy stored in chemicals like food.
fat - -ANSWER--Substance found in food that is stored to be used for energy in the
future. It also helps to keep heat in our bodies and to make the membranes of cells.
heart disease - -ANSWER--Disease caused by narrowing of the arteries carrying the
blood to the muscles of the heart so the heart muscles do not receive enough oxygen.
kilojoule (kJ) (kill-O-jool) - -ANSWER--Unit of energy used on food packets. There are
1000 J in 1 kJ.
mineral - -ANSWER--Properly called a 'mineral salt' and found in food. Needed in small
quantities for health (e.g. calcium).
protein - -ANSWER--Substance found in food that is used for growth and repair and
made of chains of chemicals called amino acids.
starch - -ANSWER--Type of insoluble carbohydrate found in plants.
sugar - -ANSWER--Type of soluble carbohydrate. Glucose is an example of a sugar.
vitamin - -ANSWER--Substance found in food that is needed in small quantities for
health (e.g. vitamin C).
absorbed - -ANSWER--When soluble substances go through the wall of the small
intestine into the blood.
anus - -ANSWER--The opening at the end of the gut.
appendix - -ANSWER--Small tube branching off the large intestine. It has no function in
humans.
contract - -ANSWER--Something gets smaller.
, digestion (dye-jes-jun) - -ANSWER--Process that breaks food into soluble substances in
our bodies.
digestive juices - -ANSWER--A liquid containing enzymes that break down food.
digestive system - -ANSWER--A group of organs that carry out digestion.
egestion (ee-jes-jun) - -ANSWER--When faeces are pushed out of the anus.
enzyme - -ANSWER--A chemical (usually a type of protein) that can break up large
molecules.
faeces (fee-sees) - -ANSWER--Waste food material produced by the intestines.
feeding - -ANSWER--Putting food into your mouth. Also called ingestion.
fibre (feye-ber) - -ANSWER--Substance found in food which cannot be used by the
body. It helps to keep our intestines clean.
gullet - -ANSWER--Tube that goes from the mouth to the stomach. Sometimes called
the 'food pipe' but properly called the oesophagus.
gut - -ANSWER--All the organs of the digestive system apart from the mouth.
ingestion (in-jes-jun) - -ANSWER--Putting food into your mouth.
insoluble - -ANSWER--Something that does not dissolve is said to be insoluble.
large intestine - -ANSWER--Organ that takes water out of waste food.
molar - -ANSWER--Grinding tooth at the back of the mouth.
rectum - -ANSWER--Organ that stores faeces before they are egested.
saliva (sall-eye-va) - -ANSWER--A digestive juice. It contains an enzyme that breaks
down starch into sugar.
salivary gland (sall-eye-vor-ee) - -ANSWER--Found in the mouth. It makes saliva.
small intestine - -ANSWER--Organ where most digestion happens. The soluble
substances produced by digestion are absorbed into the body here. It is about 6.5 m
long in adults.
stomach (stum-uck) - -ANSWER--Organ containing strong acid which mixes food up
and digests proteins.
