The correct answer is a lymph vessel that transports lymph to the lymph node.

The lymphatic system is the component of the vascular system and an essential immune system part, consisting of a network of lymphatic vessels, which transports a clear fluid known as lymph directionally towards the heart. Like the circulatory system, the lymphatic system is not a closed system.

One of the prime activities of the lymphatic system is to offer an addition return passage to the blood for the remaining three liters. The other main activity is that of defense in the immune system.
