One of the body’s many swellings in the lymphatic system, responsible for the production of lymphocytes (a type of white blood cell) and cleansing of lymphatic fluid. Lymph nodes are what get…
Lymphatic endothelial cells of the lymph node - Nature Reviews Immunology
Recent single-cell studies have revealed a previously unappreciated heterogeneity among endothelial cells that line the lymphatic sinuses of the lymph nodes. In this Review, the authors describe these various lymphatic endothelial cell types and how they support the trafficking of cells and antigens through lymph nodes.
The lymphatic system includes tissues and organs that produce, store, and carry white blood cells to fight infections. It develops beginning in the fifth week of embryonic life from lymph sacs that become lymph vessels and organs. The main components are lymph, lymph organs like lymph nodes and the spleen and thymus, lymph vessels, and lymphoid tissues. The lymphatic system works to drain fluid into the bloodstream, filter lymph and blood, and help the body fight infections by producing…

Lymph vessels bigger toward center where join Thoracic Duct= which puts fluid back into blood. Lymph Nodes= small bean structures along lymph vessels contain lymph channel, artery + vein. Allow immune sys. space to work. B/c hydrostatic pressure (push out) greater than oncotic pressure (pull in), fluid escapes blood as lymph. Edema= lymph fluid tissue buildup. Lacteals= lymph vessels in SI, package fat into chylomicrons for blood delivery. Germinal centers= Lymph nodes where B-cells…
