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

• Redness

• Cyanosis

• Swelling

• Pain

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

What are the CORRECT sequence of leukocytes recruitment?

I. Tight binding

II. Diapedesis

III. Tethering

IV. Rolling adhesion

V. Migration

• I, IV, III, V, II

• IV, I, III, V, II

• I, II, III, IV, V

• III, IV, I, II, V

Vacuole in the cytoplasm of a cell, containing a phagocytosed particle enclosed within a part of the cell membrane during phagocytosis is called

• Phagocyte

• Phagosome

• Enzymes

Phagocytosis is part of the specific immune response

• YES

• NO

Which of the following cells does not perform degranulation?

• Basophils

• Eosinophils

• Macrophage

• Neutrophils

Antigen presented on MHC class I will engage the T cell receptor on CD4 T cells.

• YES

• NO

 Pattern recognition receptors (PRR) include:

• Lipopolysaccharides

• DAMP

• dsRNA virus

• RIG-like receptors

PAMPs would be found on the surface of which of the following?

• Pathogen

• Phagocyte

• Skin cell

• Blood vessel wall

Toll-like receptors may express on the plasma and endosomal membrane, as well as in the cytoplasmic milieu.

• YES

• NO
