Blood Transfusion Reaction Case Study Flashcards
what is the first line of defense in the immune system?
Innate Immunity
Which white blood cell is most associated with phagocytosis (engulfing and destroying germs)?
macrophages
what does the adaptive immune system rely on to recognize specific pathogens
B cells and T cells
Which type of immunity is slower but more targeted?
Adaptive Immunity
which type of immune cell is responsible for producing antibodies?
B cells
Where do B cells mature?
Bone Marrow
What is the role of helper T cells in the immune response?
Activate B cells and cytotoxic T cells
Which of the following activities the adaptive immune system by presenting antigens to T cells?
dendritic cells
What are antigens?
Antigens are special proteins on the surface of pathogens
What do cytotoxic T cells do?
Attack and kill infected cells
Which organ produces T cells?
Thymus
What is a memory cell?
A cell that members pathogen for faster future response
Antigens are substances that the body sees as …
foreign or harmful
how do antibodies directly protect the body from infection?
By attaching to pathogens to neutralize or inactivate them
what is the indirect role of antibodies in protecting the body?
they signal the innate immune system to destroy pathogens
which immune cells are involved in directly neutralizing or inactivating pathogens through antibody binding?
Antibodies
what happens after antibodies bind to a pathogen?
They mark the pathogen for destruction by the innate immune system
which part of the immune system helps destroy pathogens after they’ve been marked by antibodies?
innate immune system (like macrophages and neutrophils)
what is the primary function of antibodies in the immune response?
to neutralize or inactivate pathogens and mark them for destruction
