The Body's Response to Infection

Viruses cannot reproduce by themselves and rely on the host cell's transcription and translation systems
Pathogenic viruses like Hepatitis A, B, C, D, E, and Influenza viruses cause various diseases
Ebola virus, a member of the Ebolavirus genus, attacks liver cells, endothelial cells, and immune cells
Eukaryotic pathogens like malaria-causing protists and parasitic worms can infect humans
Infectious agents can be transmitted through direct contact, indirect contact, vector-borne, inhalation, and ingestion
The body's response to infection involves innate and acquired immunity, with three lines of defense
The first line of defense includes skin and mucous membranes, which act as physical barriers and secrete chemicals
The second line of defense involves macrophages, inflammation, and fever as protective responses
The third line of defense includes lymphocytes, which recognize specific antigens and mature in different organs
B lymphocytes produce antibodies to rid the body of antigens, while T lymphocytes attack host cells bearing the antigen
Passive immunity involves the transfer of readymade antibodies, while active immunity is self-developed through exposure to antigens
Allergies are acquired hypersensitivity disorders, while AIDS is caused by HIV, which weakens the immune system and leads to opportunistic infections

Test your knowledge of the body's response to infection with this quiz. Explore the mechanisms of innate and acquired immunity, the roles of pathogens like viruses and eukaryotic organisms, and the various lines of defense the body employs. From the first line of defense to passive and active immunity, this quiz covers key concepts in infectious diseases and immune responses.
