Composition of the Blood. The light yellow colored liquid on the top is the plasma, which accounts for about 55 percent of the blood volume and red blood cells is called the hematocrit ,or packed cell volume (PCV). The white blood cells and platelets form a thin white layer, called the “buffy coat”, between plasma and red blood cells.
Various compounds, including proteins, electrolytes, carbohydrates, minerals, and fats, are dissolved in it. The formed elements are cells and cell fragments suspended in the plasma. The three classes of formed elements are the erythrocytes (red blood cells), leukocytes (white blood cells), and the thrombocytes (platelets).
