What is the role of larger lymph vessels in the lymphatic system?

Larger lymph vessels play a crucial role in the lymphatic system by transporting lymph fluid back into the bloodstream. They collect lymph from the smaller lymph vessels and facilitate its movement towards the major lymphatic ducts—the right lymphatic duct and the thoracic duct. These ducts then empty the lymph into the venous circulation at specific sites, ensuring that the fluid re-enters the bloodstream effectively. This process is vital for maintaining fluid balance in the body and for the proper functioning of the immune system, as it allows for the distribution of lymphocytes and other immune cells.
