As a group they are involved in the body’s defense mechanisms and reparative activity. White Blood Cells are called Leucocytes or Leukocytes. White Blood Cells are usually bigger than red blood cells and platelets. Abstract. Red blood cells have an average lifespan of 120 days, while white cells live anywhere from a few days to a few years, depending on the type of cell. A blood cell, also called a hematopoietic cell, hemocyte, or hematocyte, is a cell produced through hematopoiesis and found mainly in the blood.Major types of blood cells include red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes). Identification of Red & White Blood Cells. However, their most important difference is that White Blood Cells are the only ones having a nucleus. Blood is a liquid connective tissue.It is composed of a variety of cells circulating in a fluid, plasma. Abnormal amounts of these components can lead to several symptoms and health problems. A complete blood cell count (CBC) is a test that lets doctors look at your blood to get a better view of your overall health. When a person has a bacterial infection, the number of white cells can increase dramatically. There are approximately 5 million red blood cells in every cubic millimeter of blood; there are only 3,000 - 7,000 white blood cells in the same amount of blood. Blood - Blood - White blood cells (leukocytes): White blood cells (leukocytes), unlike red cells, are nucleated and independently motile. What they have in common is both have cell membranes and both circulate in the bloodstream. Difference between Red Blood Cells and White Blood Cells The significant differences between red blood cells and white blood cells are as follows: RBC – Red Blood Cells WBC – White Blood Cells Red blood cells are called Erythrocytes. Highly differentiated for their specialized functions, they do not undergo cell division (mitosis) in the bloodstream, but some retain the capability of mitosis. Blood is the fluid connective tissue and it plays a very vital role in the human body. We are not interested in plasma in this lesson, only in the cells, both white and red blood cells. White Blood Cell (Leukocyte) White blood cells are made in the bone marrow and protect the body against infection.White blood cells are bigger than red blood cells and normally are fewer in number. Blood is a fluid tissue that flows through arteries, veins and capillaries in the human body. The test measures the different components of your blood and their quantities — especially red and white blood cells. Red blood cells (or erythrocytes) are the tool our bodies use for transportation, and white blood cells (or leukocytes) are responsible for keeping us free of disease and healthy. That is the way a doctor can distinguish the ones from the others using the electron microscope when examining your blood specimens. Red blood cells aren’t proper cells once mature; they are biconcave discs filled with hemoglobin. There are several differences between red blood cells and white blood cells in structure, function and appearance. There are four primary components of blood, which are red blood cells, white blood cells, platelets and plasma. Red and white blood cells have two main functions: the carriage of oxygen; and defence against microbial attack. Blood is composed of red blood cells, white blood cells and blood platelets. Plasma makes up around 55 % of the human blood in the body. Components of blood include red blood cells, white blood cells, platelets and plasma. These cells and cell fragments are suspended in blood plasma. RBCs have a bi-concave disc shape WBCs have an irregular shape.
