MICROANATOMY

Detailed explanation-1: -Lymphatic vessels operate under low pressure, and the lymph flow through the lymphatic vessels is a slow process because the lymphatic system doesn’t include a pump. Yet, the walls of these vessels contain smooth muscles, which help lymph move forward.

Detailed explanation-2: -There is no pump in the lymphatic system like the heart in the cardiovascular system. The pressure gradients to move lymph through the vessels come from the skeletal muscle action, respiratory movement, and contraction of smooth muscle in vessel walls.

Detailed explanation-3: -Lymph is transported throughout the lymphatic vasculature by intrinsic phasic contractions generated by the lymphatic muscle of collecting lymphatics that, along with valves, are necessary for unidirectional lymph flow.
