Modes of Disease Transmission and Immune System Functions Quiz

Malaria is transmitted through the bite of infected mosquitoes.

The Zika virus is primarily transmitted by mosquitoes, which act as vectors.

Cholera is transmitted through contaminated food or water, following the fecal-oral route of transmission.

Type 1 diabetes is an autoimmune disease where the immune system mistakenly attacks insulin-producing cells.

Tuberculosis can be transmitted through respiratory droplets containing the bacteria.

Immune system does not produce hormones; its functions include defense against pathogens.

Vaccination induces active immunity, where the body produces an immune response and forms memory cells.

Passive immunity offers immediate protection through the transfer of pre-formed antibodies but is temporary.

Memory cells store information about past infections, enabling a faster response to previously encountered pathogens.

Pathogens can evade the immune system through antigenic variation, altering their surface proteins.

B cells, a type of white blood cell, are responsible for producing antibodies in the immune response.

Dendritic cells play a key role in activating T cells, a critical step in the immune response.

Innate immunity offers immediate, non-specific protection without forming immunological memory.

The complement system enhances inflammation and aids in clearing pathogens.

Cytokines play a crucial role in immune system communication, signaling, and regulating immune responses.
