a blood transfusion is when you
1. give someone extra blood after an accident or during an operation
2. take out the bad blood when someone is ill
3. change an ill persons blood by heating it
4. put healthy blood into a sick person to help them fight disease
one type of white blood cell helps to fight disease by producing chemicals called
1. antibodies
2. antihistamines
3. anti-inflammatories
4. anti-sickness tablets
vaccination is when
1. you expose a person to weakened or dead microbe so they become immune
2. deliberately infect someone to make them ill
3. give someone antibiotics to kill diseases
4. sterilise equipment before using it on a person
