The immune system does not work alone; it has a full force behind it. One of the organs that are full of white blood cells is the spleen. It is the main source helping the immune system. Another pathogen fighting organ is the thymus, making hormones and white blood cells be released into the circularatory system. Overall, in the body there are many organs helping the immune system.
The immune system protects us from getting sick constantly. It also uses WBCs, or white blood cells, to fight off the pathogen or disease. You need to follow certain steps to keep your immune system in shape.
Once the barrier is broken the immune system has full control of the brain and nervous system. It is proven that if a young child has too may protiens, or meat, the child runs a risk of being mentally ill, or depressed. The reason this happens is because when the protiens enter the body, they are used by the immune system to fight pathogens, they leave traces of the proteins. When this happens, the body reacts strangely to this, leaving the chance of depression.
The immune system also causes allergies. When the immune system fights pathogens, as I stated earlier, it leaves proteins but not as much to leave signs as depression. Those proteins trigger histamines causing you to sneeze and have all of the side affects of allergies.
You can keep your immune system healthy by doing a variety of things like washing your hands frequently to avoid getting sick. You can also be active and eat helthy foods. Your body functions by doing all of the simple things, like covering your mouth with your elbows while sneezing.
