Explanation:
Detailed explanation-1: -Unlike the blood vessels in the circulatory system, lymphatic vessels are blind-ended unidirectional absorptive vessels that transport interstitial fluid, immune cells, and macromolecules to the LNs, and from these back to the blood circulation (Figure 1).
Detailed explanation-2: -The lymphatic system is a one-way circulatory system (lymph always travels in one direction, towards the heart). It lacks a central pumping mechanism like the heart; instead, contractions of the lymph vessels push lymph through the system.
