GENERAL HISTOLOGY

Detailed explanation-1: -Lymph vessels that carry lymph to a lymph node are called afferent lymph vessels, and those that carry it from a lymph node are called efferent lymph vessels, from where the lymph may travel to another lymph node, may be returned to a vein, or may travel to a larger lymph duct .

Detailed explanation-2: -Afferent lymphatic vessels flow into a lymph node and carry unfiltered lymph fluid. Efferent lymphatic vessels flow out of a lymph node and carry filtered lymph fluid. Lymph vessels that leave the thymus or spleen (which lack afferent vessels) also fall into this category.

Detailed explanation-3: -Afferent lymph contains antigen-presenting dendritic cells, T cells and a small proportion of B cells. Lymph flow and cell output rates are low. Efferent lymph contains >98% lymphocytes with a higher proportion of B cells and much higher flow and cell output rates than in afferent lymph.

Detailed explanation-4: -Lymph vessels and nodes are not found within bone or nervous system tissue. Afferent lymph vessels flow into lymph nodes, while efferent lymph vessels flow out of them. Lymphatic capillaries are the sites of lymph fluid collection, and are distributed throughout most tissues of the body, particularly connective tissue.
