The neutrophil, a kind of white blood cell, is so strong that it commits suicide after 5 days in order to not cause a lot of damage to the human body (“The Immune System Explained”). The white blood cells are just like an army going to the battlefield because the white blood cells have many jobs some are madics ,which are the helper T cell, some are the ones in the battlefield fighting the virus or bacteria which are the neutrophils. the white blood cells have many jobs that people have in a war and they all function in a different way (“The Immune System Explained”). This means if we never had our immune system we would probably die or have to go to the hospital just for a cold. The white blood cells have a lot of functions and none of them are that similar however they all help our immune system to be strong. All the white blood cells have their own unique way of helping to kill the virus or bacteria. The white blood cell has little parts that helps it do it’s job the way it is supposed to. If the white blood cell doesn’t work the way it is supposed to, then we will get sick really fast.

=Function=

As mentioned above the white blood cells have many functions. First the bacteria enters the body some dies because macrophages however the leftover ones affect the red blood cells. Second helper-T cell reads the code on the macrophages. third that it activates the B-cell and the killer T cell. Last the B-Cell crates antibody antibodies are a large Y shaped protein that attacks the bacteria. The T killer cell attacks to the infected cell kills it. While the antibody attack at the same time and that's how the white blood cell kills the bacteria and the virus and after all the bacteria is gone then the cells that fought the bacteria dies, however the memory cells live for later on (“The Immune System Explained”). This shows the steps of how a bacteria is destroyed or killed. What happens after the battle is that the cells that fought will die except some cell which are the memory cell According to the video “The Immune System Explained,” “If this enemy is encountered ever again in the future they will be ready and they will probably kill it before you even notice. This means that even though that the cells who fought the bacteria and have experienced they are not needed because there are just memory cells that will just remember the bacteria and just create it´s weakness and just gets rid of it before it becomes too serious. There is a bunch of things that helps the white blood cells, however if they were differently made they probably wouldn't work as the same way.

=Structure=

The white blood cells create these things called Antibody, (Antibodies are little things that get created from the B cell and they are little things that attack and kill the bacteria or the virus) the Antibodies come in various different shapes and looks. Antibodies come to the fight when the bacteria is spreading too quickly The antibodies are just like a armies weapons (“The Immune System Explained”). This means that the body really needs antibodies and b cells because if not the bacteria would just overcome the macrophages and the neutrophils and the immune system will just get overrun and the body will probably die or get really sick. Imagine a world where your white blood cells were only one shape which meant they would go slower around the body which means the bacteria could just reproduce and make you get sick The white blood cells come with many many looks and shapes the common ones are a white hairy ball that travels with the red blood cells like a guard. Some white blood cells look just like red blood cells, however they don’t do the same job as a red blood cell. There is a thing called a messenger protein it’s used by the macrophages and it’s like a radio in a war if they need backup they will just send the messenger protein that helps (“The Immune System Explained”). This means that the white blood comes in a lot of shapes they are all have a their unique from or look. Their shape helps them travel through the body easier they could change their body to travel through the body easier. If the macrophages never had massenger protein it would have to run away and communicate and let the bacteria reproduces or what happens is that the macrophages die because they can’t handle it by themselves and the bacteria spreads. The white blood cells fight a lot of things such as bacteria.



=Real World Connection=

Leukemia is a disease is about white blood cells. The cancer leukemia is a disease where it will turn the white blood cells to a weird form make it damaged in a way where it keeps reproducing. Usually white blood cells die in a certain point if they reproduce too many time however these damaged cells don’t die as fast. ( Christian Nordqvist) This means that they are a stronger version of white blood cells and the white blood cells can’t kill them because of that reason even if they do they will just reproduce in really quickly and faster. Because of how much these damaged cells are producing they will take space more and more and because of that there is less space for the other cells ,such as red blood cells, and because of how much cells there are the guy who has leukemia becomes ill which could equal to bad things such as death. ( Christian Nordqvist) This means that the cancer leukemia is a really deadly to the body because one day your body will be filled with damaged white blood cells and because of that the red blood cells would have no where to travel and because of that there will. =Conclusion=

In conclusion the white blood cells is really important to the human body because it protects the body from bacteria. White blood cells make things and have parts to help it fight the bacteria, and the white blood cells helps the body by killing disease or viruses. If we never have white blood cells we would just die from a cold because the bacteria would just take control of the body. Some people might think that white blood cells are useless however if we were never had white blood cells than we would die from only one harmful bacteria. It’s always a good idea to donate some money to communities that are helping people get rid of leukemia.
