MICROANATOMY

Detailed explanation-1: -Collecting ducts: Lymphatic vessels empty the lymph into the right lymphatic duct and left lymphatic duct (also called the thoracic duct). These ducts connect to the subclavian vein, which returns lymph to your bloodstream.

Detailed explanation-2: -Unlike the blood vessels in the circulatory system, lymphatic vessels are blind-ended unidirectional absorptive vessels that transport interstitial fluid, immune cells, and macromolecules to the LNs, and from these back to the blood circulation (Figure 1).

Detailed explanation-3: -Lymphatic Function The lymphatic vasculature is comprised of unique functional features that enable entry and transport of large proteins, immune cells, lipids, and fluid against a pressure gradient (Figure 2).
