Multiple Select

Which of the following are examples of innate (non-specific) immunity?

Multiple Choice

Which is NOT one of the four characteristic symptoms of inflammation?

Multiple Choice

What are the benefits of vasodilation in the inflammatory response?

• Increases the vascular permeability so phagocytes can be recruited to the site of infection

• Decreases vascular permeability so that phagocytes can stay within the bloodstream

• Increases blood flow to allows better oxygenation

• Increases blood flow to increased hydrostatic pressure and fluid leakage which dilutes toxic agents
