All cells carry unique proteins on their cell membranes. These are called antigens, and when white blood cells come across an unfamiliar antigen, they will treat the cell (or bacterium) as hostile, and treat it as such by releasing antibodies, or by engulfing the cell.

What do our white blood cells do?

1,White blood cells are one of the four main parts of blood. The other parts are the red blood cells, platelets, and plasma. There are different kinds of white blood cells, but they all have an important job. Do you know what that job is? White blood cells defend the body from infection and disease.2,Some white blood cells go to the places in your body where you have a cut. They attack any bacteria that enter your blood to stop them from spreading throughout your body.3,Some bacteria and viruses that enter your body carry chemicals called antigens. Your white blood cells make their own chemicals called antibodies, which will attach themselves to these antigens so that the poisons from the bacteria or viruses become harmless. Do you know how amazing these cells are? Well, the antibodies that your white blood cells produce only attack the antigen for which it was made. For example, an antibody for the chicken pox virus will only attack the chicken pox virus, not the measles virus. Even more amazing is that the white blood cells in your body remember how to make the antibody in case the germ ever enters your body again!Posted: By Nabeel pervez


Why are neutrophils useful in a blood test?

Because neutrophils are a type of white blood cells; this is useful in a blood test because it can tell you how many white blood cells you have, and if you have a low amount you know why your getting sick: because your white blood cells are low so therefore they cannot attack "outsiders" or viruses. Have a nice day; and I hope this helped you out a bit. All though I have a C in Biology Semester 2. So this might not be enough information; or not the right information. But I still .!! O_o

White blood cells combat infection by?

There are different types of white blood cells, but the one we all know either releases chemicals to attack, or produce anti-bodies which bind themselves to the illness then clinging to other cels that have does the same, cause them to explode killing them selves and the bacteria. This is also why people have hey fever

Antibody act as markers by coating the outside of a bacteria or infected cell. The antibodies are produced by B cells and the purpose of antibodies is to let white blood cells and killer T cells know what to attack.


Are there more white blood cells or red blood cells?

Yes, there are (according to research) in fact more red blood cells than white. If you would like to know WHY it is because red blood cells carry oxygen through out the body while the white blood cells fight off diseases. so our bodies develop more of them for more oxygen that we need but we don't really need so much white blood cells.


What type of tissue helps blood tissue in defence?

I'm assuming you mean when you bleed. White blood cells called helper T cells attack infection and foreign materials while platelets clot the blood to keep you from continuing to bleed.

White Blood Cells prouduce antibodies because when a pathogen (another name for a diease) enters your body white blood cells sends out the right antibodies to kill the pathogen and when it is killed the white blood cells remembers it so if the pathogen ever comes back again they know how to get rid of it this is called immunty
