Red Cell Volume Can Be Accurately Determined in Sheep Using a.I 131 ALBUMIN – SERUM ALBUMIN LABELED WT RADIOACTIVE IODINE.Body water is distributed between two major compartments: Intracellular compartment 2/3 this is the water contained within cells, and bound by cell membranes. Precise volume largely depends on proportion of muscle tissue (which have more water) to adipose tissue (which has less). Plasma volume is measured using substances thatīinds specifically to plasma proteins, and will not Total body water: Water comprises 50-70 of total body weight the rest comprises solids.ECF volume is measured using substances thatĬannot enter the cells, but can freely cross theĬapillary membrane and thus distribute evenly in the.Outside the cells, but also crosses the cell membrane Marker that diffuses freely not only in the water.A marker is injected that will be evenly distributed in.Total body water is measured using dilution.
