Human Immune System

Every time a pathogen or a disease-causing organism enters the human body and threatens it, it will go through layers of hell and layers of barriers and protection. Depending on how nasty the virus or bacteria is, it may or may not survive these layers of protection which is good for us if it doesn't, bad news if it does. The layers of protection form the human immune system. Each layer of the immune system has a different and specific purpose. The first layer or the surface barriers provide the first line of defense for the human body. For example, the human body protect openings to the lungs through coughing and sneezing, mechanically ejecting irritants and pathogens. The flushing action of tears, sweat, urine and mucus serve to trap and entangle microorganisms and expel them from the body. Surface barriers can also be chemical and not mechanical. The skin and respiratory system secrete antimicrobial peptides called defensins. Enzymes such as lysozyme and A2 phospholipase in saliva, tears and breast milk are also antibacterials. Even in our stomach, powerful gastric juices can easily dissolve and destroy bacteria. If a pathogen is strong enough to survive the surface barriers, it will go through the second stage of hell, which is the innate immune system. The innate immune system is non-specific. In other words, it responds to pathogens in a generic way, regardless of what pathogen or irritant triggers it. When cells send out signals that alarm the innate immune system of damage, stress or injury or if after going through the surface barriers the irritants are identified by pattern recognition receptors of the innate immune system then the responses happen. You can actually improve your immune system through regular exercise, balanced diet, enough rest and hormone supplements and stimulants like injectable hgh. HGH is a hormone that is naturally produced in the body and can be taken as injectable hgh or dietary supplement.
