Carbon dioxide produced as a result of cellular respiration diffuses from the interstitial fluid surrounding body cells into the blood. White blood cells or leukocytes (leukos = white, cytes = cells) are so-called because they are true cells that do not contain the red protein, hemoglobin.The real value of white blood cells is that most are specifically transported to areas of infection, thereby providing a rapid and potent defense against infectious agents. As the blood reaches systemic tissues, oxygen diffuses from the blood to surrounding cells. Each human red blood cell contains approximately 270 million hemoglobin biomolecules, each carrying four heme groups to which oxygen binds. Midtown Columbus, Ga Restaurants, Some macrophages are important as antigen-presenting cells, cells that phagocytose and degrade microbes and present portions of these organisms to T lymphocytes, thereby activating the specific acquired immune response.
