What first line of defense blocks pathogens at entry sites?

Physical and chemical barriers (skin, mucous membranes, antimicrobial substances)

T cell responses

Adaptive antibodies

Which cells are the most numerous frontline phagocytes?

Erythrocytes

Neutrophils

B cells

Which cell type bridges innate and adaptive immunity by presenting antigens?

Dendritic cells

Neutrophils

Macrophages

What receptor family recognizes common microbial patterns?

BCRs

TCRs

Pattern recognition receptors (PRRs)

Natural killer (NK) cells primarily target what kind of cells?

Bacteria-only cells

Healthy cells

Virus-infected and tumor cells

Which system marks, opsonizes, and can lyse pathogens?

Coagulation cascade

Complement system

Lymphatic system

Fever is part of the innate response because it:

Directly neutralizes toxins

Causes autoimmunity

Inhibits pathogen replication and enhances immune function

Inflammation is mainly triggered by:

Antibody binding

Injury or infection activating innate immune cells

Memory T cells

Which cells release a burst of reactive oxygen species to kill pathogens?

Phagocytes (e.g., neutrophils, macrophages)

B cells

Platelets

Which statement best describes innate immunity?

Requires stimulation with an antigen

Slow, antigen-specific memory responses

Fast, non-specific defense present from birth

You can integrate the game into an LMS compatible with LTI 1.1 or LTI 1.3 such as Canvas, Moodle, or Blackboard. This way, the scores will be automatically saved into the platform’s gradebook.
