- Fluid leaks out of the thin walled capillaries as they pass through the tissues. This is called tissue fluid.
- Much of tissue fluid passes back into the capillaries. Some enters the blind-ended lymphatic capillaries that form a network between the cells of the tissues. This fluid is called lymph.
- Lymph flows from the lymphatic capillaries to lymph vessels, passing through lymph nodes and along the thoracic duct to join the blood system.
- Lymph nodes filter the lymph and produce lymphocytes.
- Other organs of the lymphatic system are the spleen, thymus, bone marrow, and lymph nodules.
