Question:
What is opsonization in the context of the immune system?
Answer:
The process by which antibodies mark pathogens for destruction.
Question:
What is the second line of defense in the immune system?
Answer:
Antimicrobial proteins and protective cells activated when the first line of
defense is breached.
,Question:
What is the role of sebum in the immune system?
Answer:
It keeps skin pliable and reduces chances of tears and abrasions.
Question:
What is the function of cilia in the respiratory tract?
Answer:
They propel mucus out of the lower respiratory tract to be expectorated or
swallowed.
Question:
What happens during isovolumetric contraction in the cardiac cycle?
Answer:
The ventricles contract with no change in volume, increasing pressure.
Question:
What occurs during ventricular ejection?
Answer:
Blood is pumped out of the ventricles into the arteries.
,Question:
What are the two pathways that activate the complement system in response
to bacterial carbohydrates?
Answer:
The lectin pathway (cascade of complete proteins) and the alternative
pathway (spontaneous binding of protein to pathogen).
Question:
What are the results of the activation of the complement system?
Answer:
Inflammation, phagocytosis, and cytolysis.
Question:
What type of cell is a Natural Killer Cell and what is its function?
Answer:
A large lymphocyte that destroys abnormal or virus-infected cells.
, Question:
How do Natural Killer Cells recognize and attack enemy cells?
Answer:
They recognize and bind to enemy cells, releasing proteins called perforins
that create holes in the membrane, and secrete granzymes that induce
apoptosis.
Question:
What are neutrophils and what role do they play in the immune response?
Answer:
Phagocytic cells that engulf and destroy pathogens; they are the first to arrive
at the site of injury or infection.
Question:
What is a respiratory burst in neutrophils?
Answer:
A process where neutrophils release toxic chemicals to kill surrounding
bacterial cells.
