Study Notes

Primary Organs of the Lymphatic System

  • The primary organs of the lymphatic system are the bone marrow, thymus, spleen, and lymph nodes.

Secondary Organs of the Lymphatic System

  • The secondary organs of the lymphatic system are the lymphoid tissues, such as the tonsils, adenoids, Peyer's patches, and lymphoid cells in the gut.

Lymphatic Drainage

  • The superficial lymphatic system drains lymph from the skin, and the deep lymphatic system drains lymph from the muscles, joints, tendon sheaths, and nerves.

Inguinal Lymph Nodes

  • The inguinal lymph nodes are located in the groin area.

One-Way Valves in Lymphatic Vessels

  • The function of one-way valves in lymphatic vessels is to prevent backflow and ensure the unidirectional flow of lymph.

Inguinal Lymph Nodes and Saphenous Vein

  • The superficial inguinal lymph nodes are arranged alongside the long saphenous vein.

Perforator Vessels

  • Perforator vessels in the lymphatic system allow lymph to flow from the superficial lymphatic vessels to the deep lymphatic vessels.
