Lymphatic tissues of Lymph Node
After leaving the bone marrow, cells travel in the blood stream and will pass through small bean-shaped structures called lymph nodes (LNs). LNs are usually <1 cm and found where blood and lymph vessels converge. THey often travel as a part of a neruovascular bundle with a nerve, artery, and vein.
Lymphatic tissues are responsible for filtering and processing antigens present in the lymphatic fluid as it travels through the lymph node (from the afferent vessels to the efferent vessel)
