Which lymphatic structures filter lymph fluid?

Explanation:
Lymph nodes filter lymph. These small, bean-shaped structures sit along lymph vessels and host immune cells such as macrophages and lymphocytes. As lymph travels into a node through afferent vessels, it percolates through subcapsular and cortical sinuses where macrophages phagocytose pathogens and debris and lymphocytes inspect antigens. This filtering traps invaders and helps initiate an immune response. The cleaned lymph exits via efferent lymphatics. By contrast, blood capillaries filter blood, not lymph; and lymph trunks or lymph collectors are the conduits that transport lymph rather than filter it.
