PATHOLOGY

Detailed explanation-1: -HIV finds the white blood cells, called CD4 cells. HIV gets inside the CD4 cell and makes copies of itself. Then, HIV kills the CD4 cell and the new HIV copies find other CD4 cells to get inside and start the cycle again. HIV kills immune system cells that help the body fight infections and diseases.

Detailed explanation-2: -Human Immunodeficiency Virus (HIV) specifically attacks Helper T cells. Without an adequate supply of Helper T cells, the immune system cannot signal B cells to produce antibodies or Cytotoxic T cells to kill infected cells.
