Right lymphatic duct

Right Lymphatic Duct

The Right Lymphatic Duct is a significant component of the human lymphatic system. It is responsible for the drainage of lymph from the right upper limb, right side of the thorax, and the right halves of the head and neck.

Structure

The Right Lymphatic Duct is approximately 1.25 cm in length and is located at the root of the neck. It is formed by the confluence of the right jugular lymphatic trunk and the right subclavian trunk, which drain lymph from the regions mentioned above. The duct then empties into the venous system at the junction of the right internal jugular vein and the right subclavian vein, forming the right venous angle.

Function

The primary function of the Right Lymphatic Duct is to return lymph to the bloodstream. Lymph is a clear, watery fluid that contains white blood cells that defend the body against germs. It circulates throughout the body in the lymphatic system, collecting bacteria, viruses, and waste products. The Right Lymphatic Duct then returns these collected substances to the bloodstream, where they can be filtered out by the kidneys and eliminated from the body.

Clinical Significance

Damage or blockage to the Right Lymphatic Duct can result in a condition known as lymphedema, which is characterized by swelling in the body tissues. This can occur due to infection, cancer, and surgical removal of the lymph nodes. Treatment for lymphedema includes physical therapy, medication, and in severe cases, surgery.
