Detailed explanation-1: -The lymphatic system produces white blood cells called lymphocytes. There are two types of lymphocytes: T cells and B cells. They both travel through the lymphatic system. As they reach the lymph nodes, they come into contact with viruses, bacteria, and foreign particles in the lymph fluid.
Detailed explanation-2: -White blood cells are made in the bone marrow and are found in the blood and lymphatic tissue. They play an important role in immune response (the immune system’s reaction to the presence of foreign substances in the body). Also called leukocyte.
Detailed explanation-3: -The tissues and organs that produce, store, and carry white blood cells that fight infections and other diseases. This system includes the bone marrow, spleen, thymus, lymph nodes, and lymphatic vessels (a network of thin tubes that carry lymph and white blood cells).
Detailed explanation-4: -Together, the blood, heart, and blood vessels form the circulatory system. The lymphatic system (lymph, lymph nodes and lymph vessels) supports the circulatory system by draining excess fluids and proteins from tissues back into the bloodstream, thereby preventing tissue swelling.
Detailed explanation-5: -Lymphatic vessels, or tubes, are the pathways that carry lymph. The major lymphatic vessels are: The thoracic duct: It begins near the lower part of the spine and collects lymph from the pelvis, abdomen, and lower chest.
