First Line of Defense: Welcome to the front line!
Components of the first line of defence, and the roles that they play.
Intact Skin
Intact skin acts as a physical wall between the inside of the body and the surrounding environment; Effectively sealing the body off from dangerous pathogens.
Mucus
In entries and exits from the body, mucus can capture large particles and organisms that could cause potential harm.
Tears
Tears are typically deployed in response to irritation of the eyes (Although James Cameron’s Titanic has been known to provoke this response), in the immune system, Tears are used to flush irritants out of the eye to prevent and cease excess damage from occurring, should an irritant or particle land on the eye.
Cilia
Cilia are little hairs that are found in places like the respirator tract (windpipe) and the Fallopian tubes. They have a similar function to mucus, with the intent of catching impurities to filter the internal environment.
Stomach acid
Not many things can live in highly acidic environments, and that’s a good thing in this case. Stomach acid has a ph between 1.5 and 3.5, and this leaves a very narrow window of what can survive in that gastric environment.
Urine flow
Urine flow is a double-barrel defence. First, you have the physical side; it’s a blast of liquid which can push out any bacteria or particles that had the intent of setting up shop in there. Second, Urine is rich in ammonia; a powerful chemical that kills bacterial and is often put in cleaning products.
Vomiting
Vomiting is the quickest way to remove a pathogen or irritant from the stomach. However, In poorer countries, vomiting is really horrible due to how much potential nutrients and hydration you lose by vomiting.
Defecation
Defecation as a response is the fastest way to remove the threatening pathogen or irritant from the bowels. This response is also known as diarrhoea. As with vomiting, this response is horrible in third world countries. Not just because of their lack of sanitation, but also because of the loss of water.
Sneezing
Sneezing is a good response to pathogens in your nose. This blast of air is actually quite powerful; 28.439 newtons of force. This violent gust can force irritants and pathogens out of the nasal cavity and back into the external environment.
Coughing
Coughing is a lot like sneezing although more sustained and often carrying more wait. Coughing is provoked by irritation of the throat and is deployed with the intent of expelling any irritants and pathogens.
