PSWD Principles of Immunology&Disease Transmission

What are the two arms of the immune system?

• Active and Passive

• Innate and Adaptive

• Anatomic and Physical

• Complement and Phagocytes

A part of the adaptive immune system

• Lymphocytes

• Neutrophils

• Monocytes

• Eosinophils

A part of innate immune system

• Neutrophils

• T-cells

• Plasma cells

• Memory B cells

An example of adaptive immunity

• Production of antibodies

• Phagocytosis of bacteria

• Release of histamine

• Activation of complement system

Innate immunity will involve this process

• Activation of classical pathway

• Activation of alternative pathway

• Activation of complement

• Involves phagocytosis

Innate immunity will involve

• Skin

• T-cell activation

• B-cell activation

• Activation of humoral response

The process whereby bacteria, animal parasites, fungi, and viruses enter host cells or tissues and spread in the body.

• Invasion

• Pathogenicity

• Toxigenicity

• Virulence

The ability of an infectious agent to cause disease

• Pathogenicity

• Virulence

• Invasion

The quantitative ability of an agent to cause disease
