## Step 1<br />Innate immunity refers to the body's first line of defense against pathogens. This includes physical and chemical barriers such as skin and mucous membranes, which prevent the entry of pathogens into the body.<br /><br />## Step 2<br />Natural killer cells are a type of white blood cell that play a crucial role in the innate immune system. They can recognize and kill virus-infected cells and tumor cells.<br /><br />## Step 3<br />Fever is another example of innate immunity. When the body temperature rises, it can help to kill off pathogens.<br /><br />## Step 4<br />Swelling is a response to injury or infection, which can help to isolate the affected area and prevent the spread of infection.<br /><br />## Step 5<br />Antibodies, on the other hand, are part of the adaptive immune system, not the innate immune system. They are produced by the body in response to specific pathogens and can recognize and neutralize them.
