Blood is a suspension of blood elements erythrocytes, leukocytes, and platelets in blood plasma. Blood elements can be separated from blood plasma using centrifugal force. Figure shows that the most descended are erythrocytes — the volume of erythrocytes in a sample of blood is called the hematocrit.

When a sample of blood is spun in a centrifuge , the cells and cell fragments are separated from the liquid intercellular matrix. Because the formed elements are heavier than the liquid matrix, they are packed in the bottom of the tube by the centrifugal force. 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.

Functions of the Blood: 8 Facts about Blood

Find GPs in Australia. The formed elements are so named because they are enclosed in a plasma membrane and have a definite structure and shape. All formed elements are cells except for the platelets, which are tiny fragments of bone marrow cells. Leukocytes are further classified into two subcategories called granulocytes which consist of neutrophils, eosinophils and basophils; and agranulocytes which consist of lymphocytes and monocytes. The formed elements can be separated from plasma by centrifuge, where a blood sample is spun for a few minutes in a tube to separate its components according to their densities. This volume is known as the haematocrit.

Composition of the Blood

Plasma , also called blood plasma , the liquid portion of blood. Plasma serves as a transport medium for delivering nutrients to the cells of the various organs of the body and for transporting waste products derived from cellular metabolism to the kidneys, liver, and lungs for excretion. It is also a transport system for blood cells, and it plays a critical role in maintaining normal blood pressure. Plasma helps to distribute heat throughout the body and to maintain homeostasis , or biological stability, including acid-base balance in the blood and body. Plasma is derived when all the blood cells— red blood cells erythrocytes , white blood cells leukocytes , and platelets thrombocytes —are separated from whole blood. The remaining straw-coloured fluid is 90—92 percent water, but it contains critical solutes necessary for sustaining health and life.

What Is Bone Marrow, and What Does It Do?

Blood is made of of several components, including red blood cells, white blood cells, platelets, and the plasma, which contains coagulation factors and serum. Blood helps maintain homeostasis by stabilizing pH, temperature, osmotic pressure, and by eliminating excess heat. Blood supports growth by distributing nutrients and hormones, and by removing waste. These cells deliver oxygen to the cells and remove carbon dioxide. Blood plays a protective role by transporting clotting factors and platelets to prevent blood loss after injury.
