Simple Explanation Of Lymphatic System

A subsidiary of the cardiovascular system, and consisting of lymphatic vessels, lymph nodes, lymph (the fluid they contain) and lymphocytes (immune cells), the lymphatic system was not appropriately portrayed until the 1600s. It was considered a plain drainage system, and basically disregarded.

It is now apparent that the lymphatic system is far more than an uncomplicated drainage arrangement, but instead involves a complex system concerned in countless conditions, ranging from cancer to asthma.

The lymphatic system is an arrangement of very fine vessels or tubes called lymphatics that drain lymph from the entire body. Lymph comprises of water, protein molecules, salts, glucose, urea, lymphocytes, and other matter.

Lymphatics are located in every part of the body apart from the central nervous system. The most important parts of the system are the bone marrow, spleen, thymus gland, lymph nodes, and the tonsils. Other organs including the heart, lungs, intestines, liver, and skin as well contain lymphatic tissue.

The key lymphatic vessel is the thoracic duct, which starts in close proximity to the lower fraction of the spine and amasses lymph from the lower limbs, pelvis, abdomen, and lower chest. It darts up through the chest and drains into the blood via a huge vein close to the left side of the neck. The right lymphatic duct assembles lymph from the right side of the neck, chest, and arm, and pours into a large vein near the right side of the neck.

Lymphocytes are white blood cells in the lymph nodes that facilitate the body’s fight against infection by creating antibodies that annihilates alien material such as bacteria or viruses.
