Explanation:
Detailed explanation-1: -A blockage of the thoracic duct would impair the drainage of lymph from inferior to the diaphragm and from the left side of the head and thorax, retarding the return of lymph to the venous blood and promoting the accumulation of fluid in the limbs.
Detailed explanation-2: -The function of the thoracic duct is to transport lymph back into the circulatory system. Interstitial fluid is collected by lymph capillaries from the interstitial space. Lymph then moves through lymphatic vessels to lymph nodes. Lymphatic vessels merge to create the lymphatic ducts which drain into the venous system.
