Unusual design makes lymphatic vessels particularly robust

Dynamic design: The cells that make up the walls of our finest lymph vessels can, if necessary, take a lobe-like shape reminiscent of an oak leaf. This cell shape makes the lymph capillaries particularly resistant to swelling in the tissue, as researchers have now found. The same cell design also supports mechanical stability in the leaves of plants, as the team reports in Nature. The lymph system permeates our entire body. Similar to the blood …
