Innate And Acquired Immunity
The immune system fights against germs and foreign substances on the skin, in the body’s tissues, and in bodily fluids such as blood. The overall ability of the host to fight the disease-causing organisms conferred by the immune system is called Immunity. The immune system can be broadly categorized into two types, the innate (Non-specific) immune system and the acquired (specialized) immune system. These two systems work closely together and take on different tasks.
