Any disease-causing organism is called a (a) .
A (a) disease is one in which a pathogen can be passed from one person to another.
What type of white blood cells produce antibodies?
lymphocytes
phagocytes
erythrocytes
platelets
White blood cells called (a) engulf pathogens, take them inside and kill them using digestive enzymes.
Every pathogen has a marker called an (a) on its surface.
Every pathogen has a different type of antigen.
This is because each pathogen's antigen has a unique (a) .
An (a) is a chemical produced by the body in response to an antigen.
Which of the following is/are true of antigens?
One, some or all answers could be correct.
They are found on the surface of pathogens
They are produced by the body
They trigger the production of antibodies
Different pathogens have different-shaped antigens
An antibody will only attach to one specific type of antigen as they have (a) shapes.
TRUE or FALSE:
"When an antibody attaches to an antigen, it marks the pathogen so it can be destroyed quicker by phagocytes."
True
False
TRUE or FALSE:
"When an antibody attaches to an antigen, it can lead to lysis (bursting) of the pathogen."
True
False
The first time that a pathogen enters the body, it can usually cause disease.
What is the main reason for this?
The pathogen changes its antigen
It takes time to produce specific antibodies to the pathogen
Antibodies cannot be produced to the pathogen
Antibodies cannot be produced to the pathogen
If we meet the same pathogen later in the future, we do not usually become ill.
What is the main reason for this?
Antibodies stay in the blood for the rest of our life
It is a weaker version of the pathogen
Memory cells remain in our blood from the first infection
Memory cells are phagocytes
Why do memory cells make sure that we do not get ill if we are infected with the same pathogen in the future?
I. They allow antibodes to be produce faster
II. They allow antibodies to be produced in a greater amount
III. They engulf the pathogen and digest it with enzymes

TRUE or FALSE:
"A vaccine contains antibodies."
True
False
A vaccine contains a weakened or killed pathogen that cannot cause disease.
However, the (a) on its surface triggers the production of specific antibodies.
Vaccines do make us produce antibodies to a pathogen.
However, more importantly, vaccines are designed to make us produce (a) (two words). It is these that remain in the blood for many years after vaccination to provide long-term protection.
TRUE or FALSE:
"Vaccines are used to treat a person with a disease."
True
False
