BIOL 1107 Exam 4 Immune
System 2026 Exam Questions
and Correct Answers | New
Update
acquired immune deficiency syndrome (aids) - ANSWER ✔✔a
disorder in which the immune system is gradually weakened and
eventually disabled by the human immunodeficiency virus (HIV).
immune system - ANSWER ✔✔a complex response system that
protects the body from bacteria, viruses, and other foreign substances
,pathogens - ANSWER ✔✔disease-causing viruses, bacteria, protists,
fungi, & parasitic worms
physical barriers - ANSWER ✔✔skin and mucous membranes
innate immune system - ANSWER ✔✔inherited mechanisms that
protect the body from pathogens in a nonspecific way
adaptive immune system - ANSWER ✔✔inherited mechanisms
leading to the synthesis of molecules that target pathogens in a specific
way
innate immunity - ANSWER ✔✔targets any invading pathogen & has
no memory of prior exposure to the pathogen
adaptive (acquired) immunity - ANSWER ✔✔recognizes individual
pathogens & mounts an attack that directly neutralizes or eliminates
them, & retains a cellular memory of a pathogen & reacts quickly upon
second exposure
immune response - ANSWER ✔✔the body's defensive reaction to
invasion by bacteria, viral agents, or other foreign substances
white blood cells (leukocytes) - ANSWER ✔✔respond to injury or
infection
, phagocytes - ANSWER ✔✔a type of white blood cell that ingests
invading microbes
thymus - ANSWER ✔✔lymphocytes form in bone marrow & then
migrate here
neutrophil - ANSWER ✔✔a type of white blood cell that engulfs
invading microbes and contributes to the nonspecific defenses of the
body against disease
lymphocyte - ANSWER ✔✔a type of white blood cell that make
antibodies to fight off infections
microorganisms - ANSWER ✔✔enter the body when injuries break
the skin or epithelial surfaces
pathogen-associated molecular patterns - ANSWER ✔✔associated
with pathogenic organisms but are absent in the host
toll-like receptors - ANSWER ✔✔each recognize a specific "danger"
molecule AND are embedded in cellular membranes
defensins - ANSWER ✔✔antimicrobial peptides that protect our
epithelial surfaces
