When the body detects an infection or abnormality, lymphocytes within the lymph nodes multiply and create antibodies to combat off the invaders. Macrophages and dendritic cells serve as scavengers, engulfing and also digesting foreign particles to avoid additional harm.
- Lymph nodes are a crucial part of the body immune system.
- They help filter lymph and capture international materials.
- Lymphocytes, macrophages, and also dendritic cells interact within the nodes to fight infections and conditions.
Location and Structure
