It triggers the immune system to produce antibodies to fight the
disease – causing agent.
is the way the body of a plant or animal protects itself against pathogens.
immune response.
is the first line of defence that protects the body or the plant or animal against pathogens.
natural immunity.
The first line response of the human body if the pathogen gets past the first line of defence is called
Inflammation and fever
is the response if the human body where pathogens are actively destroyed and the body stores a memory of the response.
acquired immune response.
The immune cells in the human body that produce antibodies are called
B lymhocytes
The immune cells in the human body that destroy the body’s cells that are infected by a virus are called
T lymphocytes
Large leucocytes that engulf pathogens by phagocytosis are called
Phagocytes
is the administration of antigenic material to obtain immunity against diseases
Vaccination/immunisation
Immunity obtained without an immune response taking place is called
Naturally acquired immunity
Immunity that is obtained by deliberate actions such as immunisation is called
Artificially acquired immunity
are chemical substances, produced from bacteria and fungi, that destroy pathogenetic bacteria
Antibiotics
B lymphocyte
Produces antibodies which fight infections
Lymphocytes which can change shape
