What type of adaptive immunity does the following statement describe?This type of immunity is acquired when antigens enter the body and an infection occurs. The immune system works to fight the infection via the innate and adaptive immune responses and creates an immunological memory of that particular antigen.
  • artificially acquired active immunityHint: What makes this type of immunity unique is that modified antigens are used to elicit an immune response. Does this sound like an active or passive process? And would you consider this to be naturally or artificially acquired?
  • naturally acquired active immunityHint: This type of immunity is not very unique in that it is acquired through daily exposure to antigens that are introduced via many different mechanisms, including everyday activities such as eating and breathing. These antigens may or may not produce a serious infections, but they do serve to create immunological memory. When they cause infection, they elicit a primary and secondary immune response.

  • Helper T cells
HIV directly infects T cells. Why is this problematic for cell-mediated immunity?
  • Correct order:1. Extracellular antigen2. B cell3 Plasma cell4 Antibodies
  • Helper T cells produce cytokines to activate other cells of the immune system
  • Cytotoxic T cells begin to attack the virally infected T cells, reducing the number of T cells in the body
  • cytokines

Which cell type is responsible for cellular immunity
  • B cells
  • T cells
  • a macrophage
  • Helper T cells
Which type of adaptive immunity does the following statement describe?This type of immunity is acquired via the passing of antibodies from a mother to a child to give immunity during the development of the child's immune system.
  • artificially acquired active immunityHint: What makes this type of immunity unique is that modified antigens are used to elicit an immune response. Does this sound like an active or passive process? And would you consider this to be naturally or artificially acquired?
  • artificially acquired active immunity?
  • naturally acquired passive immunityHint: What makes this type of immunity unique is that antibodies are passed to the child through the placenta or the mother's milk. In this case, does the child acquire the antibodies actively or passively? And would you consider this to be naturally or artificially acquired?
  • naturally acquired active immunityHint: This type of immunity is not very unique in that it is acquired through daily exposure to antigens that are introduced via many different mechanisms, including everyday activities such as eating and breathing. These antigens may or may not produce a serious infections, but they do serve to create immunological memory. When they cause infection, they elicit a primary and secondary immune response. Does this sound like an active or passive process? And would you consider this to be naturally or artificially acquired?

  • a. Innate Immunityb. Humoral Immunityc. Cellular Immunityd. Immature B cellse. Dendritic cellsf. Th cellsg. Memory cellsh. Plasma cellsi. Cytotoxic T cellsHint: There are three types of B cells. Immature B cells have not yet "learned" to what they should respond. They require a signal from helper T cells to know that. Once activated, immature B cells mature into effector B cells (called plasma cells) and memory B cells which will become rapidly activated should the intruder return.
