Question

DESCRIBE which of these components of the immune system would participate in the following scenario:

Components -

Skin, Mucous membranes, Mucus, Sebum, Gastric juices, T helper cells, Cytotoxic T cells, B cells, Antibodies, Cytokines, Interferons, NK cells, Macrophages and dendritic cells, Basophils, Neutrophils, Eosinophils, Complement, Lacrimal apparatus

1. E. coli found inside a poorly cooked hamburger patty. Remember, E. coli has the capability to produce toxins and is Gram-negative therefore has endotoxin present as well

Answer 1

All the given things except Skin,Sebum(because E.coli is entering along with food);NK cells(because NK cells act only on virus);Basophils,Eosinophils(involved in allergic reactions);Lacrimal apparatus(have their role in keeping moist condition in eyes orbital) are involved in immune response of host.

Mucous membrane and mucus traps pathogens and prevents epithelia from getting infection.Gastric juice is involved in destroying bacteria because of it's low ph(high acidity).T helper cells, Cytotoxic T cells are involved in cytotoxic immunity. B cells, Antibodies, , Macrophages ,dendritic cells are involved in Humoral immunity. Complement system identifies bacteria and destroys by opsonisation, Cytokines, Interferons are produce by infected cells ,which signals neighbouring cells to defend against invading bacteia.
