Detailed explanation-1: -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.
Detailed explanation-2: -From their terminal ducts to their sources between the cells of the tissues, the lymph vessels divide and subdivide repeatedly, becoming narrower at each division. A system of valves in the larger vessels keeps the lymph flowing in one direction.
Detailed explanation-3: -Lymphatic Vessels The wall of the lymph capillary is composed of endothelium in which the simple squamous cells overlap to form a simple one-way valve. This arrangement permits fluid to enter the capillary but prevents lymph from leaving the vessel.
