In this video lecture, educator describes the Lymphatic system. The components of lymphatic system are Lymph, Lymphatics, Lymphatic Trunks and Lymphatic Ducts. The lymphatic system protects the body against foreign material and transports dietary fats. Lymphatic System continues Lymph, Network of vessels, Lymph nodes and nodules, tonsils, spleen, Thymus gland and Bone marrow.
Lymph derives from tissue fluid and contains more white blood cell than plasma. It flows through sinuses in lymph node cortex and then into the medulla. The Lymph Capillaries are microscopic closed ended vessels. Where Lymph Vessels resemble veins, but have thinner walls and more valves.
Lymph Trunks are formed by lymphatic vessels uniting and Lymph empties into two conducting ducts i.e. the right lymphatic duct. The Thoracic Duct is about 15-18 inches in length.
The Lymph Nodes are covered by a capsule and contain capsular extensions called trabeculae. Major lymph Nodes are Cervical, Axillary, Inguinal and Mesenteric.
