White Blood Cells and Inflammation Quiz

What are the four parts of blood—three are formed elements and one is liquid?

• Red blood cells (erythrocytes)

• White blood cells (leukocytes)

• Platelets (thrombocytes)

• Plasma (liquid portion)

Which two types of leukocytes are the most prevalent in the blood?

• Neutrophils

• Lymphocytes

• Monocytes

• Eosinophils

List the leukocytes which are phagocytic.

• Neutrophils

• Macrophages (derived from monocytes)

• Dendritic cells

• Eosinophils (to a lesser extent)

What is pus and what is it a sign of?

How are mast cells similar to basophils? How are they different?

List some examples of pathogen-associated molecular patterns (PAMPs).

• Lipopolysaccharides (LPS) on gram-negative bacteria

• Peptidoglycan on gram-positive bacteria

• Flagellin (in bacterial flagella)

• Viral RNA or DNA

What are pattern recognition receptors (PRCs) and how are they associated with PAMPs?

List the steps of phagocytosis, including the terms phagosome and phagolysosome.

Why do phagocytic cells increase their uptake and consumption of oxygen?

What are the benefits of inflammation? What are the concerns?
