Final answer:
Yes, lymph drains into the low-pressure venous circuit at the subclavian veins through the right lymphatic duct and the thoracic duct, which is true.
Step-by-step explanation:
The statement that lymph drains into the blood of the low-pressure venous circuit at the subclavian veins is true. Lymphatic fluid, which is absorbed by the lymphatic capillaries, is eventually transported into larger lymph vessels and trunks. Specifically, the right lymphatic duct drains lymph from the upper right side of the body into the right subclavian vein, and the thoracic duct drains the lymph from the rest of the body into the left subclavian vein. This ensures that the lymph is effectively returned to the bloodstream, maintaining the critical balance of fluids in the body.
