What are the 4 phases of the immune response?

This can be broken down into four stages: the lag, exponential, steady state, and declining phases. This is the time from initial antigen exposure to when antibodies are detected in the blood, and takes about a week. In this time, specialized B and T cells are activated by contact with the antigen.

Is Internal Audit second or third line of Defence?

The third line of defense is internal audit, which provides assurance (acting with independence) on the effectiveness of governance, risk management, and internal controls. The current Three Lines of Defense model is delineated by: Operational management (first line)

Is inflammation first or 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 are the 3 lines of defense?

The original Three Lines of Defense model consisted of the first line (risk owners/managers), the second line (risk control and compliance), and the third line (risk assurance).

Is saliva a first line of defense?

Summary: Our saliva consists of water and mucus, among other things, and the mucus plays an important role. … It stimulates white blood cells to build a good defense against invaders, according to a group of researchers.

What are the 3 types of immunity?

Is your immune system weaker after a vaccine?

Also, vaccines do not make a child sick with the disease, and they do not weaken the immune system. Vaccines introduce a killed/disabled antigen into the body so the immune system can produce antibodies against it and create immunity to the disease.

What is the first line of defense against a cyber attack?

FirewallThe visibility and traffic filtering that a firewall provides enables an organization to identify and block a large percentage of malicious traffic before it enters the network perimeter and can provide defense in depth.

What is the 1st 2nd and 3rd line of defense?

The first line of defense are the physical and chemical barriers, which are considered functions of innate immunity. … The third line of defense is specific resistance, which is considered a function of acquired immunity.

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 line of defense are vaccines?

The immune system is an extremely important defence mechanism that can identify an invading organism and destroy it. Immunisation prevents disease by enabling the body to more rapidly respond to attack and enhancing the immune response to a particular organism.

Do vaccines stay in your body forever?

Sometimes one dose of a vaccine is enough to protect a person, but often more than one dose is needed. Some antibodies protect for a lifetime, but others need boosting. For example, measles antibody lasts a lifetime, but antibody to tetanus can fall below a level that protects you, so booster doses are needed.

What is the body’s second line of defense?

The second line of defense is nonspecific resistance that destroys invaders in a generalized way without targeting specific individuals: Phagocytic cells ingest and destroy all microbes that pass into body tissues. For example macrophages are cells derived from monocytes (a type of white blood cell).
