As blood flows through capillaries, some plasma leaks out through gaps between capillary cells and into the spaces between tissue cells, forming tissue fluid. Tissue fluid is similar to plasma but contains fewer protein molecules, which are too large to pass through the capillary gaps. Red blood cells also cannot pass through, but some white blood cells such as neutrophils can squeeze into the tissue fluid. Other small molecules in tissue fluid include glucose, urea, amino acids, and water. Tissue fluid is drained by the lymphatic system.

5.  As blood flows through the ? , some of the ? leaks out
through the ? between the cells of capillary walls, and
seeps into spaces between the cells of the tissues. This
liquid is called ?. 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

fluid include ?, urea, amino acids and water.
