Lymphatic capillaries are one-way vessels designed to allow fluid to flow in a single direction, aided by valves and structural adaptations.
Lymphatic capillaries are one-way vessels due to specific structural adaptations. They are lined by endothelial cells that overlap, allowing fluid to enter but preventing backflow. Valves in lymphatic vessels ensure fluid flows in one direction, preventing retrograde flow. The thoracic duct serves as a major conduit for lymph drainage.
