What are Lymph Nodes?
- Small filtering stations
- Full of phagocytes & lymphocytes
- Grow in size as they are fighting off pathogen
What does the spleen do?

- Sub-Acute Phase (3 days-several months)
- Maturation Stage (3 months to a full year or more)
Specific or Adaptive Immune responses is the very last line of defense, how does this happen?
It is acquired after time through exposure to specific pathogens.
B-Cells
Recognize antigens that are not self
T-Cells
Must be introduced to an antigen for it to recognize it as a foreign invader.
Artificially acquired immunity
Is immunization by vaccination
