What cell type kills cells infected by a virus as part of the specific immune response quizlet?
Helper T cells activate B cells and cytotoxic T lymphocytes to kill infected host cells. Helper T cells produce and secrete antibodies. Helper T cells phagocytize bacteria and viruses. An activated B cell divides into cells that give rise to memory B cells and plasma cells.
What is the purpose of humoral immunity?
Humoral immunity is also called antibody-mediated immunity. With assistance from helper T cells, B cells will differentiate into plasma B cells that can produce antibodies against a specific antigen. The humoral immune system deals with antigens from pathogens that are freely circulating, or outside the infected cells.
What type of T cells can directly attack and kill other cells such as virus infected cells?
Activated B cells, by contrast, secrete antibodies that can act far away. There are two main classes of T cells—cytotoxic T cells and helper T cells. Effector cytotoxic T cells directly kill cells that are infected with a virus or some other intracellular pathogen.

What are the primary cells involved in immunity?
The cells of the immune system can be categorized as lymphocytes (T-cells, B-cells and NK cells), neutrophils, and monocytes/macrophages. These are all types of white blood cells. The major proteins of the immune system are predominantly signaling proteins (often called cytokines), antibodies, and complement proteins.
Do helper T cells kill viruses?
Instead, T-cells are like a special forces unit that fights only one kind of virus that might be attacking your body. There are two types of T-cells in your body: Helper T-cells and Killer T-cells. Killer T-cells do the work of destroying the infected cells. The Helper T-cells coordinate the attack.
