Amylase
An enzyme produced in the
salivary glands
and pancreas that breaks carbohydrates down into simple
sugars
Aorta
The main artery that takes
oxygenated
blood
away
from the heart to the body
Artery
A blood vessel that carries blood at
high
pressure
away
from the heart
Benign tumour
An
abnormal
cell
growth
that is contained within one area and does not invade other areas of the body
Bile
A substance made in the
liver
and stored in the
gallbladder
which is used to neutralise stomach acid in the intestine and emulsify fats
Blood
A tissue containing
red blood cells
, white blood cells,
platelets
and plasma
Cancer
A
non-communicable
disease caused by changes in the cell that lead to
uncontrolled growth
and division
Capillary
A very
thin
blood vessel that is used for
exchange
of substances
Cell
The basic
building block
of all living
organisms
Communicable disease
A disease that can be
spread
between
individuals
either directly or indirectly
Coronary heart disease
A disease caused by the buildup of
fatty
deposits inside the coronary artery, narrowing it and reducing blood flow to the heart tissue
Enzymes
Biological
catalysts
that
increase
the rate of reactions in living organisms
Health
The state of
physical
and
mental
wellbeing
Heart
An organ that
pumps blood
around the body in a
double circulatory
system
Lipase
An enzyme that is produced in the pancreas that breaks
lipids
down into
fatty acids
and glycerol
Lock and key hypothesis
A theory that describes how substrates must be the correct
shape
to fit the
active site
of an enzyme
Malignant tumour
A cancerous cell
growth
that invades neighbouring tissues and can spread to different parts of the body in the
blood
Meristem tissue
Plant tissues
containing
undifferentiated stem cells
Metabolism
All of the
chemical
reactions occurring in an
organism
Non-communicable disease
A disease which
cannot
be
spread
between individuals
Organs
Aggregations
of
tissues
performing specific functions
Organ systems
Groups of
organs
that work together to form
organisms
Palisade
mesophyll
A tissue found in plant
leaves
that is specialised to carry out
photosynthesis
Phloem
A
transport
tissue found in plants which is specialised to transport
sugars
from source to sink
Protease
An enzyme produced in the stomach and
pancreas
that breaks proteins down into
amino acids
Pulmonary artery
The main artery that takes
deoxygenated
blood away from the heart to the
lungs
Pulmonary vein
The main vein that takes
oxygenated
blood back to the
heart
from the lungs
Rate of
reaction
The
speed
at which reactants are
converted
into products
Risk factor
Something that
increases
a person's risk of developing a
disease
Spongy mesophyll
A tissue found in plant
leaves
that is specialised for
gas exchange
Statins
A class of drugs that are used to reduce blood
cholesterol
levels which slows down the rate of
fatty
material deposit
Stent
A tube that can be
surgically implanted
into
blood vessels
to keep them open
Tissue
A group of
cells
with a similar structure and
function
Translocation
The movement of
food
molecules through the
phloem
tissue
Transpiration
The process of water
evaporating
from a plant
Vein
A
blood
vessel that carries blood at a low pressure back to the
heart
Vena cava
The main vein that takes
deoxygenated
blood back to the
heart
from the body
Xylem
A
transport
tissue in plants which is specialised to transport
water
and dissolved minerals from the roots of the plant to the leaves
