lymphatic vessels begin as lymphatic cap pillories made up of overlapping and affiliate all cells. The overlapping flaps function as a one way valve. When fluid accumulates in the tissue, interstitial pressure increases pushing the flaps inward, opening the gaps between cells, allowing fluid to flow in as pressure. Inside the cap Ilary increases, the endothelial cells air pressed outward, closing the gaps, thus preventing backflow. Unlike blood capillaries, the gaps and lymphatic capillaries air so large that they allow bacteria immune cells such as macrophages and other large particles to enter.
