state in which physical, emotional, intellectual, and social development is diminished impaired
establishment of a pathogen in a susceptible host
freedom from and prevention of disease-causing contamination
3 main defenses against infection
substances that provokes an adaptive immune response
Types of adaptive immunity
humoral and cellular
