IMMUNOLOGY

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: -The lymphatic system is a network of delicate tubes throughout the body. It drains fluid (called lymph) that has leaked from the blood vessels into the tissues and empties it back into the bloodstream via the lymph nodes.

Detailed explanation-3: -Lymph vessels are tubes that carry lymph through the body to lymph nodes and back to veins. The network of lymph vessels is similar to blood vessels (arteries and veins) that carry blood. Lymph vessels carry waste products, germs and damaged cells away from the body’s tissues.

Detailed explanation-4: -The various efferent lymphatic vessels in the body eventually converge to form two major lymphatic channels: the right lymphatic duct and the thoracic duct. The right lymphatic duct drains most of the right upper quadrant of the body, including the right upper trunk, right upper extremity, and right head and neck.
