White+Blood+Cells+-+KP

=1. Introduction=

toc Have you ever gotten sick? Ever gotten a fever? Ever gotten the stomach bug? Have you ever wondered how you got sick in the first place? pathogens, and **white blood cells** are the reason. They have a huge role in your immune system White blood cells are in the immune system, and they are considered the //"superheros"// of your body, and immune system. =2. How Do WBC's Work?=

**White blood cells** are in the **immune system**. The immune system is a system in your body that helps you not get sick, and get rid of the bad cells, called pathogens. White blood cells are called ¨The superheros¨ of the body, because they protect your insides. First, the T cells recognizes **pathogens,** a bad cell that spreads diseases. The T cells then produce more and more T Cells that can identify the germ. Then, the T cells attack the killed cells that contain viruses and disease. Then, the t-cells activate the B cells to produce antibodies. Antibodies are proteins produced by B cells. After, the antibodies attack on the pathogen. The viruses clump together are attacked by phagocytes. =3.What happens When They Fail?=

If you have a low white blood cell count, your body can't function as well.This is called neutropenia If you have a low white blood cell count, you will get symptoms such as sore throat, fever (above 100.5 F, or 38 C) chills, congestion, shortness of breath, infections, and also sores in the mouth, On the other hand, you probably won't feel any symptoms if you have an extremely low count.

White blood cells are usually caused by blood **cancers,** and blood cancer treatments. Some of these include **Chemotherapy, Radiation therapy**, cancers of the blood and bone marrow and cancers that spread. ( **metastasize** ). Chemotherapy to treat the disease, by chemicals. Radiation therapy is a type of treatment that uses beams of energy to kill cancer. As a result, you can develop an infection, and this infection can lead to death in extreme cases. a way to solve this is to keep a balanced diet, exercise daily, and also take frequent blood tests to make sure your blood is healthy.

=4.Different Types=

There are several different types of white blood cells. **T-cell s ** job is to identify the pathogens,and **B-cells** job is to produce antibodies, a protein that helps destroy pathogens. **Neutrophils**, are the most common. About 70 % of white blood cells are Neutrophilos. Neutrophilos are **phagocytic**, which means they can digest pathogens.. Another type of white blood cell is the **Basophil,** which help the body protect itself from harmful diseases, viruses or pathogens.Also, **Eosinophils** help with mechanisms related to **Asthma**.Asthma is a respitory infection causing troubled breathing. **Lymphocytes** also help protect the body. They are seven to eight diameters in length. Another kind of White blood cells are Monocytes, they are the largest form of defense in the immune system. Macrophages are about twenty milameters in length,



=5.Antibodies=

**Antibodies** are a Y-shaped protein produced by **Plasma cells,** also known as b-cells.They are a blood protein that is used to identify harmful viruses or diseases. A virus is a harmful infectious cell that replicates inside living cells. A disease is also an infected cell that circulates throughout the body. Antibodies are also known as **immunoglobulin**. Antibodies is one of the main functions of the immune system. Each antibody binds to a specific pathogen, which means they attack on one specific germ, or pathogen.This is another way pathogens get killed. =6. Vaccines=

**Vaccines,** also called shots are a substance that simulate the production of antibodies. As we saw earlier, Antibodies are a really important part in the bodies immune system. Vaccines are made of dead infections, that allows the antibody to get alarmed, and does not allow that infection to come in. They defend against harmful viruses or bacteria before you get infected.it's important to get vaccines for diseases that are airborne, which means that they are in the air.

One example of this is the flu. The flu, also known as influenza is a disease that spreads throughout the lungs, nose, and throat. =7.Conclusion=

White Blood Cells are really important to the human body. They protect your immune system, by producing antibodies. On the other hand, there are several different types of white blood cells, including, **neutrophil, eosinophil, basophil, monocyte and lymphocyte**. Once you become older, you may focus on your white blood cell count a little more and take frequent blood tests.

White blood cells are known as “the superheros of the Immune system, because without them, you would not be able to function correctly. Now you know how you get over Congestion, a fever, sore throat, the flu, chickenpox, or just a simple cold.They are a really important cell in the human body.
