A - Crystalloids prevent fluid loss out of the circulation, colloids are used for maintenance fluid therapy 晶体液防止循环中的液体流失，胶体液用于基础的液体疗法
B - Colloids are albumin and globulins, crystalloids are 5% dextrose and normal saline 胶体液含有白蛋白和球蛋白，晶体液分为5%的葡萄糖和一般生理盐水
C - Crystalloids are electrolytes in water, colloids are crystalloids with high molecular weight polymers added 晶体液是含有电解质的水，胶体液是晶体液中加入了高分子聚合物
D - The addition of proteins to a crystalloid makes it a colloid 晶体液中加入蛋白就变成了胶体液
