MICROANATOMY

Detailed explanation-1: -The various efferent lymphatic vessels in the body eventually converge to form two major lymphatic channels: the right lymphatic duct and the thoracic duct.

Detailed explanation-2: -The right lymphatic duct is a terminal lymphatic vessel located in the neck, anterior to the anterior scalene muscle. It is typically formed by the union of the right bronchomediastinal, right jugular and right subclavian lymphatic trunks, although its formation is highly variable.

Detailed explanation-3: -The medulla is the innermost layer of the lymph node and contains large blood vessels, sinuses, and medullary cords. The medullary cords contain antibody-secreting plasma cells, B-cells, and macrophages. The medullary sinuses (or sinusoids) are vessel-like spaces that separate the medullary cords.
