are leukocytes part of lymphatic system
This picture shows the regions of the lymph node where the blood stream (arteries and veins) anter a typical lymph node. For the lymphatic system to function properly in its defensive role, the lymph nodes must be able to dump their leukocytes (infection fighting cells) quickly into the general blood stream. It is important to note that white blood cells are not produced in the Lymph nodes initially, only stored there. In the event of a serious infection (a pathogenic virus for example), the lymph nodes often become very swollen. Lymphocytes, the primary cells of the lymphatic system, make up roughly one-fourth of all white blood cells in the body. Like other white blood cells, they are produced in the red bone marrow. Lymphocytes constantly travel throughout the body, moving through tissues or through the blood or lymph vessels. 1 Since the lymphatic system does not have a heart to pump it, its upward movement depends on the motions of the muscle and joint pumps.  As it moves upward toward the neck the lymph passes through lymph nodes which filter it to remove debris and pathogens. The Lymphatic System - Design: parts of the lymphatic system. A network of vessels, tissues, organs, and cells constitute the lymphatic system. Included in this network are lymph vessels, lymph nodes, the spleen, the thymus, and lymphocytes. Running throughout this network is a watery fluid called lymph. Lymph comes from the Latin word lympha , meaning clear water.. 1 The lymphatic system aids the immune system in removing and destroying waste, debris, dead blood cells, pathogens, toxins, and cancer cells.  The lymphatic system absorbs fats and fat-soluble vitamins from the digestive system and delivers these nutrients to the cells of the body where they are used by the cells. Lymphocytes - T cells and B cells. White blood cells called lymphocytes originate in the bone marrow but migrate to parts of the lymphatic system such as the lymph nodes, spleen, and thymus. There are two main types of lymphatic cells, T cells and B cells. The lymphatic system also involves a transportation system - lymph vessels - for transportation and storage of lymphocyte cells within the body. The macrophages (big eaters) are slower to respond to invaders than the granulocytes, but they are larger, live longer, and have far greater capacities. Macrophages also play a key part in alerting the rest of the immune system of invaders. Macrophages start out as white blood cells called monocytes. The rest of the cortex contains T lymphocytes- cells that circulate through the lymph nodes, blood stream, and lymphatic ducts to seek out any infection. The medulla of the lymph nodes is primarily made up of macrophages attached to reticular fibers. 1 The lymphatic system absorbs fats and fat-soluble vitamins from the digestive system and delivers these nutrients to the cells of the body where they are used by the cells.  The lymphatic system also removes excess fluid, and waste products from the interstitial spaces between the cells. The receptors match only one specific antigen.

Yes,leukocytes are part of lymphatic system.
