=Introduction= toc One day, you are sick. You might think that your body only needs medicine that can treat your sickness. But one thing you don’t realize is that not only does medicine help, the WBC is always helping you to fight for your body and kill off viruses/ bacteria. Have you ever wondered what is a white blood cell? A WBC is just like our country armed forces such as the Navy, Air Force, and the Marines. There are many WBC in our body but there are millions of them. They fight diseases and bacteria that hurts your body. There are also good bacteria in our body that helps us. The bone marrow reproduces millions of them. Did you know about HIV yet? HIV is a virus that kills every immune system in your body? This is caused by when people that is not related to you and when their blood by accidentally went through your skin if you have a cut. This progress will cause 100% HIV. The function is one of the important questions of the WBC. The structure of the WBC helps them to success easily.

=Function=

There are many WBC but there are three basic ones. All of them have a similarity of its job which is destroying the bacteria/ virus. One of them is called a Phagocyte and its function of it is, they absorb bacteria and let it not live again. Another WBC is called the T- cells, they identify __pathogens(__ germs, bacterias, and viruses that hurt your body) so other white blood cells don’t confuse the good bacteria from the bad.( Padilla et al #) This WBC is like cops that arrest the bad person and let the innocent people go. The third WBC is B-cells and their function is to produce a protein that helps destroy pathogens. This is how they attack viruses or bacteria; When you get a cut, several bacteria can get in your body. Bacteria start reproducing more. After they overpopulate, they start to hurt your body. Therefore the macrophage, a type of the white blood cell，is the biggest and attacks the bacteria. Next, when they fight for a long time, T cells produce messenger protein or a receptor protein to communicate location and urgency. The B- cells then get the message to go to the war to help.The T-cells trap the bacteria and kill the bacteria. Then the T-cells suicide themselves after 5 days so the war would end.

=Structures=

Did you know that the structures of the WBC help them to do its job easier? White blood cell has a lot of structures. For example, the WBC can change their shape so then they can surround the bacteria or virus then eat them. This structure can help them sneak up on them because the bacteria/Virus can not identify them by their shape. Another structure is they produce antibody, the definition of antibody is a protein that attacks the bacteria/virus. Only the B-cell that can produce antibody. Although,the B-cell can also reproduce the antibody. In addition, they also use this protein that can identify bad bacteria that hurt your body and this structure is call the receptor protein. Those Structures is like tools that help them succeed.

Imagine this if you have a disease, this disease can be your deadly nightmare because HIV is unstoppable. HIV is a disease that is caused by if you have a cut and their blood go through and mix with your blood to create this Virus call HIV.(Discovery Education). HIV kills off all the WBC, they will stop if every WBC dies. The only WBC cell that can kill off HIV is the T-cell but after they eat the HIV they will get infected then they will die. HIV needs more helper so then they will have to infect the bone marrow( This cell reproduce White blood Cell) to help them reproduce millions of HIV. According to the Discovery Education video about WBC, the author says that “HIV can’t be fully cured but you can kill some of them with medicines that can help a little.” This quote shows how HIV will stay forever with you for your rest of the lifetime.



=Conclusion=

The work of white blood cells not appreciated and recognized even though they do all the work of killing the virus and bacteria. But there is one virus that can destroy them which is HIV. Imagine every immune system dies, you will easily be sick and your body is full of germs that are spreading around your body. The immune system does everything to protect us and they even sacrifice themselves to kill all the bacteria and viruses. Without the WBC we could not live a happy life.
