Defenses of Human Immune System and how They Are Influenced by Hereditary Genetics

The immune system is greatly affected by genetics and hereditary traits. The immune system is the body's defense against pathogens, such as bacteria and viruses. The immune system is a two-part defense mechanism, with specific and non - specific defenses. Non specific defenses are defenses that function against all forms of invaders.
