Q6.2. There are many diseases that do not infect a person more than once, such as chicken pox and measles. What is responsible for this lifetime immunity? The innate immune response, because barriers to entering the body improve with age. The innate immune response, because adults have more white blood cells than children. The acquired immune response, because antibodies are developed from previous infections. The acquired immune response, because it responds rapidly to broad classes of pathogens.

Immunology

Immunology is the division of science involved with the immune reactions occurring in living organisms. The organisms are accustomed to evolving internal defense mechanisms to evade the invasion of microbial pathogens. Diverse cells are connected with stimulating the immune responses, which produce inhospitable conditions to the microbes prompting their lysis and thus inhibits the multiplication of the pathogens. The immune system can distinguish the pathogens through the aid of cellular intercommunication and launch responses to destroy them.
