Explanation:
Detailed explanation-1: -The innate immune system constitutes the first line of host defense during infection and therefore plays a crucial role in the early recognition and subsequent triggering of a proinflammatory response to invading pathogens (242).
Detailed explanation-2: -The second line of defence is a group of cells, tissues and organs that work together to protect the body. This is the immune system.
Detailed explanation-3: -The first line of defence (or outside defence system) includes physical and chemical barriers that are always ready and prepared to defend the body from infection. These include your skin, tears, mucus, cilia, stomach acid, urine flow, ‘friendly’ bacteria and white blood cells called neutrophils.
