Guided Notes
3 key concepts
- 1
The innate immune system is nonspecific, meaning it responds to general threats without recognizing specific pathogens.
- 2
Lymphocytes, including B cells and T cells, are the main actors in the adaptive immune system, which develops after exposure to antigens.
- 3
B lymphocytes participate in the humoral response, which targets pathogens in bodily fluids, while T lymphocytes participate in the cell-mediated response, which targets infected cells.
