What Structural Feature of Lymphatic Vessels is Responsible to Forward

Question

What structural feature of lymphatic vessels is responsible to forward movement of lymph?
A) over-lapping endothelial cells
B) valves
C) no basement membrane
D) thin walls

Accepted Answer

The valves in lymphatic vessels are responsible for maintaining the forward flow of lymph. They prevent backflow and ensure that the lymph moves in one direction, towards the heart. The other structural features listed may play a role in lymphatic function, but they are not specifically responsible for forward movement of lymph.
