In the lymphatic system, a lymph node is a secondary lymphoid organ. [4] Diagram of a lymph node showing lymphocytes. The primary function of lymph nodes is the filtering of lymph to identify and fight infection. In order to do this, lymph nodes contain lymphocytes, a type of white blood cell, which includes B cells and T cells.
The lymphatic system, or lymphoid system, is an organ system in vertebrates that is part of the immune system, and complementary to the circulatory system. It consists of a large network of lymphatic vessels, lymph nodes, lymphoid organs, lymphatic tissue and lymph. [1][2] Lymph is a clear fluid carried by the lymphatic vessels back to the ...
Lymph nodes of the lungs: The lymph is drained from the lung tissue through subsegmental, segmental, lobar and interlobar lymph nodes to the hilar lymph nodes, which are located around the hilum (the pedicle, which attaches the lung to the mediastinal structures, containing the pulmonary artery, the pulmonary veins, the main bronchus for each side, some vegetative nerves and the lymphatics) of ...
The meningeal lymphatic system is composed of a network of vessels along the dural sinus in the dura which express lymphatic endothelial cell marker proteins, including PROX1, LYVE1, and PDPN. The vessels extend along the length of both the superior sagittal and transverse sinuses and directly connects to the deep cervical lymph nodes. [1]
Lymph (from Latin lympha 'water') [1] is the fluid that flows through the lymphatic system, a system composed of lymph vessels (channels) and intervening lymph nodes whose function, like the venous system, is to return fluid from the tissues to be recirculated. At the origin of the fluid-return process, interstitial fluid —the fluid between ...
Axillary lymph nodes. The axillary lymph nodes or armpit lymph nodes are lymph nodes in the human armpit. Between 20 and 49 in number, they drain lymph vessels from the lateral quadrants of the breast, the superficial lymph vessels from thin walls of the chest and the abdomen above the level of the navel, and the vessels from the upper limb.
Regional lymph tissue. (Infraclavicular labeled at upper left.) One or two deltopectoral lymph nodes (or infraclavicular nodes) are found beside the cephalic vein, between the pectoralis major and deltoideus, immediately below the clavicle. They are situated in the course of the external collecting trunks of the arm.
Submental lymph nodes. Superficial lymph glands and lymphatic vessels of head and neck. (Buccinator glands labeled at center right.) The submental lymph nodes (or suprahyoid lymph nodes[citation needed]) are 2-3 lymph nodes [1] situated in the submental triangle, [1] between the anterior bellies of the digastric muscle and the hyoid bone.
