Immunity

     All living organisms are continously exposed to substances that are capable of causing them harm. Most organisms protect themselves against such substances in more than one way with     
physical barriers,for example or with chemicals that repel or kill invaders.Animals  with backbones called vetebrates,have these types of general protective mechanisms,but they also have a                   more advanced  protective system called the immune system.

The immune system is a complex network of organs containing cells that recognize foreign substances in the body and destroy them.It protects vertebrates against pathogens or infectious agents such as viruses,bacteria,fungi,and other parasites.The human immune system is the most complex.

               Among the many uncertainties that remain about covid-19 is how the human system responds to infections and what that means for the spread for the disease
