What is the function of the immune system?
To carry Oxygen, water and nutrients to the cells and remove CO2 and waste from the cells.
To control the movement of the body by sending and receiving electrical impulses.
To protect the body from foreign invading pathogens that may make the body ill.
To make gametes that will be used for future creation and development of a zygote.
What is considered a pathogen?
A foreign invader of the types: viruses, bacteria, fungi, protists.
A foreign disease of the types: Arthritis, Salmonella, heart disease, gout.
An illness of the body caused by cancer, allergies, dehydration or dementia.
A foreign particle that gets inside your body of the types: antibodies, antivirals, vaccines or antibiotics.
What is considered as your body's FIRST line of defense?
Your inflammatory response
The antibodies you were born with that your mother gave you in utero and through breastmilk.
The attack performed by B cells and T cells against pathogens.
Your skin and mucous membranes.
What is another general name given to white blood cells?
Lymphocytes
Erythrocytes
Bryophytes
Sporophytes
If a pathogen is able to penetrate your skin, how does your body react to it next? What is the SECOND line of defense?
Reaction causes an inflammatory response, with extra fluid and heat to the invaded area.
Reaction causes B cells to mark the pathogen for destruction.
Reaction causes Helper T cells to call more white blood cells.
T cells arrive at the point of entrance of the pathogen to engulf and destroy it.
What type of white blood cell helps the non-specific second line of defense?
Helper T cells
Cytotoxic T cells
B cells
Macrophages
Where are B Lymphocytes (B cells) made?
In the Thymus
In the Bone Marrow
In the Lymph Nodes
In the Brain
What to B cells produce?
Antibiotics
Antivirals
Antigens
Antibodies
What is an antigen?
It is a protein present on the outside of pathogens that is unique to them
It is a protein produced by B cells that sticks to pathogens and immobilize them.
It is a treatment given to patients to fight off pathogenic infections.
It is a chemical produced by killer T cells that destroy infected cells in our body.
B cells and T cells for part of which line of defense?
First line of defense
Second line of defense
Third line of defense
Fourth line of defense
B cells fight disease in which battlefield/area of your body?
In the skin
In the fluids of your body
Inside your infected cells
In your brain only
If the cells in your body get infected and they become machines for replicating pathogens, what type of white blood cells come to destroy them specifically?
T cells
B cells
Helper T cells
macrophages
The role of T cells is specific to what type of response?
The skin
The inflammatory response
The humoral response
The cell-mediated response
Where do T cells mature?
In the Thymus
In the Thorax
In the Thyroid
In the Tonsils
TRUE or FALSE: Antibiotics work against viruses.
True
False
Although vaccines cannot be used to treat a person who is already sick, they can help to prevent infections. Vaccinations tell the body to create "memory cells", which will function later to create antibodies against that pathogen if it is ever encountered again. When a person is vaccinated, what are they injected with?
Antibodies to a disease bacterium
Weakened or inactive viruses or the antigen of the virus
Live, active viruses in very small quantities.
Blood plasma from a person that had the disease
What happens the second time you are exposed to a pathogen?
The body will not be able to fight off the pathogen quickly because the pathogen learned how to get into your body easier.
The body can only be exposed to a pathogen a second time if you do not have a vaccine.
The body's immune system will react the same way as it did during the first exposure.
The body will remember how to fight off the pathogen quickly because it created memory B cells after the first exposure.
How do T cells differ from B cells?
T cells fight pathogens by killing them or the cells they infect directly while B cells fight pathogens by making antibodies to flag and immobilize them.
T cells fight pathogens by making antibodies, while B cells fight pathogens by killing the pathogens directly
T cells make memory cells and B cells make antibiotics
T cells can only fight pathogens that the body has encountered before while B cells are non-specific and they fight off any pathogen.
If you get sick with measles once, it is likely you will develop immunity to it if you ever encounter it again within your lifetime. What type of immunity would this be?
Active immunity
Passive immunity
What immunity? You will get sick again!
Temporary immunity. You will need a yearly shot of it will not work.
When babies are born, they possess some antibodies that were given to them by their mothers while in utero or passed to them through breast milk. What type of immunity would this be?
Active immunity
Passive immunity
Permanent immunity
Innate immunity
