How are white blood cells and red blood cells different?
White blood cells, or leukocytes (also spelled ‘leucocytes’), are cells of the immune system defending the body against both infectious disease and foreign materials. Five different and diverse types of leukocytes exist, but they are all produced and derived from a multipotent cell in the bone marrow known as a hematopoietic stem cell. Leukocytes are found throughout the body, including the blood and lymphatic system. Red blood cells are the most common type of blood cell and the vertebrate body’s principal means of delivering oxygen to the body tissues via the blood. The cells are filled with hemoglobin, a biomolecule that can bind to oxygen. They take up oxygen in the lungs or gills and release it while squeezing through the body’s capillaries. The blood’s red color is due to the color of hemoglobin. In humans, red blood cells develop in the bone marrow, take the form of flexible biconcave disks, lack a cell nucleus, subcellular organelles and the ability to synthesize protein, and l
Red blood cells and white blood cells are some of major components of blood. Red blood cells are those which contains haemoglobin and helps oxygen and carbon dioxide to bind. White blood cells are defense mechanism of human body towards various organisms and foreign body invasion. In case of any major infection the number of white blood cells increase in number in order to fight the infection, while in case of some infections the red blood cells are destroyed. In some people decrease in these red blood cells witness decrease in haemoglobin. This is called as anemia. While in some diseases there is increased no of white blood cells called as lecocytosis. This happens in case of most types of blood cancers namely leukemia.
