Question

Acquired immunity involves both a humoral immune response and a cell-mediated immune response. To review the definitions of these immune responses, see Hint 1.
Sort the items into the appropriate bins depending on whether they are involved in the humoral response, the cell-mediated response, or both the humoral and the cell-mediated responses.

antigen presenting cells

plasma cells

memory cells

antibodies

b cells

helper T cells and cytokinesis

cytotoxic T cells

The categories are humoral response, cell mediated response, and both

Answer 1

Answer:

Humoral response.

• Plasma cells
• Antibodies
• B-cells

Cell mediated response.

• Antigen presenting cells.
• Helper T-cells and cytokines.
• Cytotoxic T- cells

Both.

• Memory cell

Explanation:

• Immunity is typically divided into two categories- innate and adaptive.
• Innate immunity is present since birth and consist of many factors that are relatively non-specific.
• Adaptive immunity is also known as specific or acquired immunity, is capable of recognizing and selectively eliminating specific foreign antigen.

• Adaptive immunity displays four characteristic features; Antigen specificity, Immunologic memory, Diversity, Self or non-self recognition.

• There are two branches of acquired immunity, which involve different sets of participants and different purposes but one common aim: to eliminate the antigen.
• One arm of adaptive immune response is mediated by B-Cells and circulating antibodies. This is referred to as humoral immunity.

• The other arm of adaptive immune response is mediated by T-cells, which do not synthesize antibodies but release cytokines that affect other cells.
• T-cell receptors do not form antibodies  but perform various effector functions when antigen presenting cells bring antigen into the secondary lymphoid organ.
• T-cells are of two types ; T- helper cell and T-cytotoxic cells.

Answer 2

Answer:

T cells identify pathogens based on antigens on the surface of pathogens. The T cells then multiply and stimulate B cells to produce antibodies. The antibodies attach to the antigens, making the pathogens a target for phagocytes.
