Immune System Quiz

What are the two interrelated parts of the immune system described in the text?

• Nonspecific innate immunity and specific adaptive immunity

• Physical defenses and chemical defenses

• Cellular defenses and physical defenses

• Chemical defenses and adaptive immunity

Why are nonspecific innate defenses described as "nonspecific"?

• They target specific pathogens

• They defend against a wide range of potential pathogens

• They have memory and improve over time

• They are acquired over time

Which of the following is NOT a characteristic of nonspecific innate defenses?

• They provide an immediate response against potential pathogens

• They have no memory and do not improve after repeated exposures

• They are acquired over time

• They can sometimes be circumvented by pathogens

What is the role of the microbiome in nonspecific innate immunity?

• It serves as a chemical barrier

• It competes with and inhibits the growth of pathogens

• It produces antibodies

• It provides cellular defenses

Which of the following is an example of a chemical mediator found in body fluids?

• Thrombocytes

• Platelets

What type of cells are characterized by a lobed nucleus and granules in the cytoplasm?

• Erythrocytes

• Thrombocytes

• Granulocytes

• Platelets

Which of the following is NOT a type of granulocyte?

• Neutrophils

• Eosinophils

• Basophils

• Thrombocytes

What is the result of the collective response of chemical mediators and cellular defenses to an injury or infection?

• Hematopoiesis

• Phagocytosis

• Inflammation

• Granuloma formation

What can chronic inflammation result in if the inflammatory response is unsuccessful?

• Hematopoiesis

• Phagocytosis

• Granulomas and scarring

• Leukocyte formation
