## Step 1<br />The body's second line of defense is called the immune system. This system is composed of various cells, tissues, and organs that work together to protect the body from harmful substances such as bacteria, viruses, and other foreign invaders. The immune system is activated when the first line of defense, which includes physical and chemical barriers like skin and mucus, is breached.<br /><br />## Step 2<br />The kind of white blood cells that take part in the inflammatory response are called neutrophils. These cells are a type of phagocyte, which means they can engulf and digest foreign invaders like bacteria. When an infection occurs, neutrophils are among the first responders to the site of infection, where they help to destroy the pathogens and prevent the spread of the infection.<br /><br />## Step 3<br />The third line of defense in the body is called the adaptive immune system. This system is more specialized and targeted than the first two lines of defense. It involves the activation of specific cells and antibodies that can recognize and remember specific pathogens, providing long-term immunity. The adaptive immune system is responsible for the body's ability to develop immunity to certain diseases after exposure to them.
