What are the body’s lines of defense?

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.

Is the inflammatory response the second line of defense?

The second line of defense attacks pathogens that manage to enter the body. The second line of defense includes the inflammatory response and phagocytosis by nonspecific leukocytes.

What cells are involved in the second line of defense?

Why are there 3 lines of defense?

The Three Lines of Defense model provides a simple and effective way to enhance communications on risk management and control by clarifying essential roles and duties. … Each of these three “lines” plays a distinct role within the organization’s wider governance framework.

What is the body’s first line of defense?

innate immune systemThe first line of defence is your innate immune system. Level one of this system consists of physical barriers like your skin and the mucosal lining in your respiratory tract. The tears, sweat, saliva and mucous produced by the skin and mucosal lining are part of that physical barrier, too.

What are the 5 parts of the immune system?

The main parts of the immune system are: white blood cells, antibodies, the complement system, the lymphatic system, the spleen, the thymus, and the bone marrow. These are the parts of your immune system that actively fight infection.

What is the three lines model?

What are the differences between the 3 lines of defense?

There are three lines of defense: the first is to keep invaders out (through skin, mucus membranes, etc), the second line of defense consists of non-specific ways to defend against pathogens that have broken through the first line of defense (such as with inflammatory response and fever).

Is Fever second line of defense?

If pathogens do manage to enter the body, the body’s second line of defense attacks them. The second line of defense includes inflammation, phagocytosis, and fever.

Which line of defense is most important?

The third line of defense is most important because it involves the cells and proteins of adaptive immunity, responding directly to specific antigens. All three lines of defense depend on each other to function properly and no single line is more important than the other.
