37 HIV & The Immune Response Standard 10E & 10FHIV & The Immune Response
38 30. (10f) Cells that are directly responsible for the production of antibodies are Red Blood CellsPhagocytesT-cellsB-cells
39 31. (10e) HIV weakens the immune system by killing AntibodiesB CellsHelper T CellsKiller T Cells
40 32. (10e) HIV spreads through the body by Replicating inside the cells of the immune system.Preventing the body from producing antibodies against HIV.Causing the body to have asthma attacks.Strengthening the immune system.
