Study Notes
White Blood Cell Functions
- White blood cells (WBCs) are crucial components of the immune system that combat pathogens.
- WBCs use a process called phagocytosis to engulf and digest harmful microorganisms.
- Some WBCs release antibodies, which are proteins that specifically target and neutralize pathogens.
- Antibodies enhance the ability of the immune system to recognize and eliminate foreign invaders.
- Certain WBCs produce antitoxins to neutralize toxins released by pathogens, preventing damage to the host's cells.
Edward Jenner's Contribution
- Edward Jenner pioneered the concept of vaccination in the late 18th century.
- He discovered that cowpox provided immunity to smallpox when he inoculated a boy with cowpox lesions.
- This method laid the foundation for immunology and the development of vaccines against various diseases.
Vaccines: Definition and Process
- A vaccine is a biological preparation that provides acquired immunity to a particular infectious disease.
- Vaccines usually contain an agent resembling the disease-causing microorganism, which is often weakened or killed.
- The vaccination process stimulates the immune system to recognize and fight the pathogen without causing the disease.
- Upon vaccination, the immune system forms memory cells that remember the pathogen, allowing for a quicker response upon future exposure.
