Select the true statement
all immunogens are antigens
all antigens are immunogens
antigens are produced by T lymphocytes to defend against non-self antigens
antigens are produced by B lymphocytes to defend against immunogens
Do all antigens elicit an immune response?
Yes
No
Thick waxy cuticles are an example of
Physical Barriers
Chemical Barriers
Microbiological Barriers
Epithelial cells in animals would be an example of
Physical barriers
Chemical barriers
Microbiological barriers
Acidic vaginal secretions would be an example of
Physical barrier
Chemical barrier
Microbiological barrier
Innate immune responses include (select one or more)
Occur within hours
Typically take weeks
Are fixed responses
Lead to memory
Don't lead to memory
Select the different types of innate immune cells
Basophil
Macrophage
Mast cell
Chemokines
Dendritic cell
Complement proteins circulate in the lymph vessels and help kill foreign cells
True
False
Interferons are non-specific and will act on any virus
true
false
Select all the cells/molecules involved in inflammation
Mast cells
Neutrophils
Basophils
Cytokines
Histamines
A fever will decrease the replication of pathogens like viruses and bacteria by destroying the genetic material within the pathogens.
True
False
Pus contains leukocytes
Yes
No
immunity in an organism
causes it develop a disease after exposure to a pathogen
makes it unable to respond to an infective agent
makes it able to resist infection
is the absence of a vaccination
During the great plague in the seventeenth century millions of people died. Others, many who often tended sick people, remained unaffected.
It is most likely that these unaffected people had:
systems were unable to identify the plague-causing organism
systems that were unable to produce T and B cells
a natural immunity to the plague-causing organisms
been vaccinated against the plague-causing organism
Inflammation involves the
decrease of blood flow to an area
generation of heat in an area
decrease of capillary permeability
removal of white blood cells near the area
An event that leads to the development of inflammation is
taking oral medicine to treat an infection
phagocytes engulfing bacteria
an infective agent entering a cut in the skin
applying ointment to a wound area
Innate immune responses are critical to maintaining the health of an individual because:
they are specific to the antigens on the pathogenic organisms
the innate response produces antigens which bind antibodies to mast cells
they provide immediate and continuous protection against foreign antibodies
none of the above
Natural active immunity is achieved as a result of:
exposure to live attenuated vaccines
infection by a particular bacteria or virus
the administration of antibodies or antitoxin specific to a particular microorganism
adequate breast-feeding in newborn infants
Lupus is a condition that results in the increased secretion of antibodies that attach themselves to healthy cells in a patient’s body. The accumulation of these antibodies causes inflammation, joint pain, rash, fatigue and fever.
Lupus is an example of
an allergic reaction.
an autoimmune disease.
an immune deficiency disease.
a complement protein response.
Antigen-presenting cells deliver antigens to lymphocytes found within lymphoid tissue. These lymphocytes recognise these antigens as being non-self, causing the lymphocytes to become activated and increase in number. Which of the following lymphocytes are activated by antigen-presenting cells?
T helper cells
dendritic cells
plasma cells
neutrophils
mAb's that have been attached to a chemotherapy drug, toxin or radioactive particle are an example of:
Bispecific mAb's
Chimeric mAb's
Humanised mAb's
Conjugated mAb's
