Blood may be described as a red liquid that flows through a network of arteries and veins in all vertebrates and is essential for life. Basically, there are three types of blood cells - red blood cells (RBC), white blood cells (leukocytes) and platelets. While the red blood cells enclose a substance known as hemoglobin and also transport oxygen to the tissues, the platelets that are created in the bone marrow are essential for formation of blood clots. In addition, blood is made up of water, numerous diverse types of proteins, inclusive of antibodies, crucial hormones and transport molecules, nourishing substances like fats, sugars and amino acids and most essentially, living cells. In fact, all the three blood cells are produced in the bone marrow and they develop from a cell called hematopoietic stem cell. It may be noted here that the deadly disease leukemia is a cancer caused by the abnormal development of the white blood cells.
Plasma is a placid dilute liquid belonging to a group of compounds that maintain the resistance of capillary walls to infiltration and pressure altercations in humans. Plasma does not contain any cell, but is utilized as a prop up device for numerous cells that remain floating in it. Nevertheless, plasma is just not a carrier of cells, but encloses several substances like proteins (antibodies and albumin that are essential for the thickening of blood), glucose, vital minerals (sodium, calcium, potassium, chlorine and others), soluble fats (triglycerides and cholesterol) as well as numerous substances that are produced during organic activities (lactic acid, urea, creatine and others) that ascertain the appropriate performance of our body.
