Describe the pathway to how the adaptive immune system would become activated if a toxoid passed through a lymph node. Recall, lymph nodes have two types of resident antigen presenting cells. Start from one of the immune cells that detects the toxoid – be sure to include which immune cells are involved, what receptors are present, and what the outcome is. Then, start from the second immune cell that can detect the toxoid and follow the same format.

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.
