PATHOLOGY

Detailed explanation-1: -The innate immune system is the body’s first line of defense against germs entering the body. It responds in the same way to all germs and foreign substances, which is why it is sometimes referred to as the “nonspecific” immune system.

Detailed explanation-2: -Physical barrier The skin is the impermeable physical/mechanical barrier that protects many pathogens from entering the body. Similarly, mucosa or mucous membranes that line the immediate internal systems help trap pathogens by producing mucous.

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.

Detailed explanation-4: -First line of defense: Owns and manages risks/risk owners/managers. Second line of defense: Oversees risks/risk control and compliance. Third line of defense: Provides independent assurance/risk assurance.

Detailed explanation-5: -Barrier defenses are part of the body’s most basic defense mechanisms. The barrier defenses are not a response to infections, but they are continuously working to protect against a broad range of pathogens.
