If the osmolarity of plasma (inside a capillary) is 300 mOsM, the osmolarity of the tissue fluid (interstial fluid) is 400, and the membranes are permeable to water but not to salts or proteins, in which direction will water move (from the capillary into the tissue or from the tissue into the capillary)? If the lymphatic vessels remove proteins from the interstitial fluid, will the osmolarity of the interstitial fluid increase or decrease?
