Tissue fluid is very similar to blood plasma except that it contains far fewer ? molecules as these are too ? to escape through the tiny holes in the capillary endothelium. ? blood cells are also too large but some ? blood cells such as ? can squeeze through the gaps. Other small substances that are found in tissue fluid include ?, urea, amino acids and water.
