Immunity

After an initial infection, B-cells recognize the measles virus. How is this helpful in human immune response? 

• The B-cells use this recognition to defend the body against other pathogens, such as bacteria.
•  The B-cells more quickly recognize and respond to any other virus that invades the body.
• The B-cells produce antibodies more quickly if the measles virus is encountered again.
• The B-cells transfer this recognition to T-cells, which will then devour the viruses.

The body's first line of defense against pathogens is

• barriers.
• inflammatory response.
• immune system.
• lymphatic system.

Weakened microbes that stimulate the immune system to produce antibodies used to fight future invasions by the same microbe. Example: chicken pox, measles, small pox

• Vaccine

• Disease

• Immunity

A protein, produced by the immune system that either attacks invading pathogens or marks them for killing.

• Antibodies

• Microbe

• AIDS

• Allergy

Which is an example of passive immunity?

• people being vaccinated against disease
• people taking vitamins to boost their immune response
• people receiving antibodies from their mothers before birth
• people producing antibodies against organisms that cause diseases they have had previosuly

A secondary immune response will be faster when...

• The individual has encountered the pathogen already

• The individual's macrophages are on high alert

• The individual has encountered the pathogen and has memory B cells circulating

• Antibodies are produced by T cells

Antibiotics do not work on

• bacteria

• viruses

• HIV patients

• children

Which best describes the relationship between antibodies and antigen?

• One antibody can affect several different antigens.

• Antibodies are specific to one antigen.

• Antigens are produced in response to antigen.

• Immunity develops when an antigen destroys an antibody.

Immunity that occurs when a person's own immune system produces antibodies in response to the presence of a pathogen when a person gets sick

• Natural Passive Immunity

• Natural Active Immunity

• Artificial Active Immunity

Immunity in which antibodies are given to a person rather than produced within the person's own body

• Artificial Passive Immunity

• Natural Passive Immunity

• Artificial Active Immunity
