What is the difference between rbc and wbc

Production number. Almost 2 million RBC are produced in the body per second. Formation process. The process of RBC formation is called Erythropoiesis. The process of EBC formation in the body is called Leucopoiesis. Red Blood Cells are non-motile. White blood cells are motile. Percentage in blood. This percentage, however, differs according to the height, weight, and age of the person. Red blood cells are only of one type. White blood cells are of multiple types. T-lymphocytes, B-lymphocytes plasma cells , monocytes macrophages , neutrophils, eosinophils, and basophils are some of the types of WBC.

Life span. RBC can survive up to days in the body. WBC can survive anywhere between several days to even several years in the body. RBC is made up of only haemoglobin. The presence of haemoglobin lends a red colour to the RBC. It is the reason they are called red blood cells. The absence of haemoglobin makes WBC colourless. The primary function of the RBC is to carry oxygen to the various parts of the body.

As a secondary function, they also carry waste materials and carbon dioxide to the lungs. The primary function of WBC is to produce antibodies to strengthen the defence mechanism of the body. These antibodies protect the body from any attack by germs and provide immunity against infections. There are normal values for the total number of each type of white cell.
