Study Notes

Transmissible diseases are caused by pathogens that can be passed from one host to another.
Pathogens can be transmitted through direct contact with body fluids, contaminated surfaces, food, animals, or through the air.
The body has defenses like skin, nose hairs, mucus, and stomach acid to prevent pathogen entry.
White blood cells destroy pathogens that breach these defenses and enter the body.
Disease spread can be controlled through clean water, hygienic food prep, personal hygiene, safe waste disposal, and sewage treatment.
Each pathogen has unique antigens with specific shapes.
Lymphocytes produce antibodies that bind to antigens, helping destroy pathogens.
Memory cells are formed by lymphocytes upon encountering antigens, providing long-term immunity.
Antibody production and memory cell formation from lymphocytes lead to active immunity.
