Innate or nonspecific immunity is the defense against infection that can be activated immediately once a pathogen attacks. It protects you against all antigens. These mechanisms include physical barriers such as skin, chemicals in the blood and immune system cells that attack foreign cells in the body. The innate immune system is fundamentally made up of barriers that intention to keep viruses, bacteria, parasites and other foreign particles out of our body or limit their ability to spread and move throughout the body.

Inflammation is the body’s response occurs when tissues are damaged by bacteria, toxins, heat, or any other cause. The aim is being to remove harmful stimuli, including damaged cells, irritants, or pathogens and begin the healing process. These damaged cells release chemicals including histamine, bradykinin and prostaglandins.
