The Band Test. The back and front of your bra band should be level and parallel to the floor when you look at yourself from the side in a mirror. If the band is too tight, digs into your flesh or is just plain uncomfortable, it's too small.
Phagocytes are the white blood cells that protect the body by eating (phagocytosing) dirt, bacteria and dead or dying cells. They are important for fighting infections. They are also important for becoming immune. Phagocytes are important in all animals and are very complex in vertebrates.
This material is then displayed to other cells of the immune system. Some phagocytes then travel to the body's lymph nodes and display the material to white blood cells called lymphocytes. This process is important in building immunity, and many pathogens have evolved methods to evade attacks by phagocytes.hagocytes occur in many species; some amoebae behave like macrophage phagocytes, which suggests that phagocytes appeared early in the evolution of life. Phagocytes of humans and other animals are called professional or non-professional depending on how effective they are at phagocytosis.
