Test Bank for Pathophysiology 9th Edition Mccance 2023 ANS: A B-cell function is altered with age as shown by decreases in specific antibody production in response to antigenic challenge, with concomitant increases in circulating immune complexes and in circulating autoantibodies (antibodies against self-antigens). Aging does not play a role in either decreasing T cells circulation or increasing helper T cells production. PTS: 1 DIF: Cognitive Level: Remembering 25....

Immune System correct answer: *Defends Body Against invasion or infection by antigens *Patrols for and destroys abnormal/damaged cells Excessive Immune Response correct answer: Over-or Hyper functioning of immune system Deficient Immune Response correct answer: Ineffective immune response Autoimmunity correct answer: Immune System attacks its own tissues *Cause: abnormal excessive immune responses -individual immune system recognizes its own cells as foreign and mounts an immune ...

What is the role of the immune system in host defense? correct answer: To provide defense against antigens and other infectious agents via innate immunity or adaptive immunity. What is the difference between central and peripheral tolerance? correct answer: Central tolerance is the mechanism by which newly developing T cells and B cells are rendered non-reactive to self while peripheral tolerance is immunological tolerance developed after T and B cells mature and enter the periphery. Def...
