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.
