Physical Therapist Assistant PTA: Lymphatic System

The lymphatic system is a system of capillaries, vessels, nodes and other organs that transport a fluid called lymph from the tissues as it returns to the bloodstream. The lymphatic tissue of these organs filters and cleans the lymph of any debris, abnormal cells, or pathogens.

The lymphatic system includes several components; it’s a network of vessels, ducts, and nodes, as well as organs and diffuse tissue. These structures work to filter unwanted substances out of the bloodstream and body tissues.
