DEFENSE AGAINST BACTERIA/VIRUSES
Even though bacteria/viruses can damage any cell, some cells can fight the mRNA off. In order for a virus or bacteria to get into our system it has to go through a cut or bug bite which means that our first defence system is our skin and if our skin is damaged or cut it means that more bacteria and viruses can go through. Other than our skin there is another way to defend yourself from the prophage, that's vaccines. Everybody has hear of vaccines or have taken a vaccine once in their lives to defend themselves from a disease. How vaccines work is that it injects a small portion of that disease into your body and allows the white blood cells to eat the disease and develop a greater immunity to that disease. The third way to fight of bacteria/viruses is by Phagocytosis, which is when the host's white blood cells "eat" the virus particle and destroying it with enzymes in their lysosomes. The white blood cell is attracted to the bacteria because proteins called antibodies have marked the bacteria for destruction. These antibodies are specific for disease-causing bacteria and viruses. Unfortunately this process doesn't always work due to the bacteria's ability to multiply rapidly and faster than the white blood cells and that causes the viruses to develop resistance and defeat the white blood cells. We also have an immune system which processes down an organism and detects pathogens to defend off bacteria. There are two different processes in our immune system fights off these diseases, Interferon and Antibodies. Interferons are proteins made by an infected host cell before it dies and signals the other cells to defend against the virus. Once the signal in triggered it activates the immune cells to kill the virus. While interferons work individually antibodies attach to a virus, clump together and deactivate the virus. These antibodies are highly specific proteins made by the white blood cells to make their job easier since once the viruses are deactivated they are easy to be destroyed by the white blood cells. With these responses to viral infections allow us to not be sick and full of disease all the time because without these processes we would be dying since there is 10X more bacteria cells in our body than normal cells.
