Bacteria are living cells and can multiply rapidly. Once inside the body, they release poisons or toxins that make us feel ill.
BACTERIA GET IN BETWEEN CELLS

RELAY NEURONES
Front
Neurones that carry information from a sensory nerve cell to a motor nerve cell

MMR
Front
MEASLES, MUMPS AND RUBELLA

WHITE BLOOD CELLS CAN
Front
-ingest pathogens and destroy them
-produce antibodies to destroy pathogens
-produce antitoxins that neutralise the toxins released by pathogens
white blood cells do not eat the pathogens - they ingest them
Back
REFLEX
Front
-a way for the body to automatically and rapidly respond to a stimulus to minimise any further damage to the body.
stimulus → receptor → sensory neurone → relay neurone → motor neurone → effector → response
Back
CENTRAL NERVOUS SYSTEM (CNS) consists of
Front
- the brain and spinal cord
Back
RELAY NEURONE
Front
-carry messages from one part of the CNS to another
Back
VACCINES
Front
ARE SMALL AMOUNTS OF DEAD / WEAKENED PATHOGENS
Back
SYNAPSE
Front
Where two neurones meet, there is a tiny gap called a synapse. Signals cross this gap using chemicals released by a neurone. The chemical diffuses across the gap makes the next neurone transmit an electrical signal.
Back
DEPENDENT VARIABLE
Front
WHAT YOU MEASURE- ON Y AXIS
Back
RECEPTORS
Front
- can detect a change in the environment (stimulus) and produce electrical impulses in response. Sense organs contain groups of receptors that respond to specific stimuli.
Back
CONTROL VARIABLE
Front
VARIABLES THAT REMAIN CONSTANT OR UNCHANGED
Back
SYMPTOMS OF AN INFECTION
Front
PAIN, FEVER, RASH, NAUSEA, HEADACHE, COUGHING
Back
VIRUSES
Front
Viruses can only reproduce inside host cells, and they damage the cell when they do this
VIRUSES GET INTO CELL
Back
ANTIBODY
Front
PRODUCED BY WBC WHEN IMMUNE SYSTEM DETECTS A PARTICULAR PATHOGEN
Back
DECAY
Front
The breakdown of dead plant and animal material by fungi, bacteria and other organisms. Requires WOW
W-warmth
O-oxygen
W- water
Back
MOTOR NEURONE
Front
A motor neurone sends impulses from the spinal cord/CNS to effector (muscle of gland).
Back
DISEASES CAUSED BY VIRUSES
Front
influenza - flu, colds, Measles, mumps, rubella, chicken pox, AIDS
Back
NEUROTRANSMITTER
Front
Back
PANDEMIC
Front
A DISEASE THAT IS SPREAD RAPIDLY ACROSS MANY COUNTRIES
Back
EPIDEMIC
Front
WIDESPREAD OUTBREAK OF AN INFECTIOUS DISEASE WITHIN A COUNTRY
Back
EFFECTORS
Front
-produces a response e.g.muscle contracts to move hand away from stimulus or gland squeezes and releases hormone into blood.
