The lymphatic system is a network of vessels, tissues, and organs in the body that helps maintain fluid balance and defend against infections. It consists of lymphatic vessels, lymph nodes, the thymus, spleen, and bone marrow:
• Lymphatic vessels are similar to blood vessels, but instead of carrying blood, they transport lymph, a clear fluid that contains white blood cells, proteins, and other substances.
• Lymph nodes are small, bean-shaped structures located throughout the body that filter lymph and trap bacteria, viruses, and other harmful substances.
• The thymus is a small gland located behind the breastbone that produces T cells, a type of white blood cell that helps fight infection.
• The spleen is an organ located in the upper left part of the abdomen that filters blood and helps remove old or damaged red blood cells.
• The bone marrow is the spongy tissue inside bones where blood cells are produced.
