These vessels carry the lymph liquid consisting of immune cells and also waste products right into and also out of the lymph node, permitting the immune system to place an efficient defense versus microorganisms.
- Capsule: The outer layer made up of connective cells.
- Lymphoid roots: Compartments in charge of filtering foreign compounds.
