Innate And The Immune System

The immune system depends on the body’s structures to help it function. For instance, the skin acts as the “body’s first line of defense.” If a pathogen finds a breach in the skin barrier, it is the circulatory system that must now signal the immune system of the invader. Shortly after, white blood cells will be notified of the infection and will target and destroy the pathogen.

The innate immune system is effective to a certain degree. That said, if the environment is regulated then the body is less likely to get ill. Innate immunity is effective as once the patient matures his immune system will mature due to the B and T memory cells. The memory cells will help the body prepare for the virus once it has arrived. The memory cells will send specialised lymph nodes to the invading pathogen. The B and T memory cells are key to immunity of a virus.

Innate immunity refers to nonspecific defense mechanisms that come into play immediately or within hours of an antigen's appearance in the body. Adaptive immunity refers to antigen-specific immune response.

The body’s protection against viruses, bacteria and other types of invasions is our immune system (Tortora, 2014).

The innate and adaptive immune response start with exposure to an antigen in the epithelium of

Innate Immune System – Nonspecific and abrupt first response; comprised of epithelial surfaces (physical barriers), neutrophils, and macrophages.

Defense mechanisms are said to be specific because depending on which one they focus on one specific part of the body or a specific type of pathogen.

Answer: Innate immune system or nonspecific resistance is also known as first line of defense. It’s nonspecific that means not design to target any specific microorganisms. Response time for innate immune system is very quick compare to adaptive immune system. These infections inhibited by the substance that change the humoral or cellular component of the host that mediated non specific resistance. They are not specific means they provide protection against a spectrum of organism. And they are vitamin, minerals, fatty acid and microbial product. These substances are major part of our diet. We consume food and get from it. Diet has both

The immune system is made up of trillions of specialised cells (white blood cells) that detect and destroy pathogens or their toxins. Some white blood cells, which are

Human beings are born with immunity as well as they acquire it from the environment they grow in. Human innate immunity is assigned the task to hinder the harmful substances from entering the body. These immunity barriers develop a defense line. The innate immunity includes cough, tear enzymes, mucus, skin and the stomach acid. Hence, the role of innate immune system is to stop harmful materials from entering our body. In case the innate immunity is insufficient to fight, there is acquired immunity that fights harmful substances by getting exposed to various antigens. The acquired immunity is developed against specific antigen. Its role is to fight

The immune system consists of a defense system that guards the body against invasion from infections and other diseases. Normally, a healthy person's immune system has the capability to differentiate between its own cells and cells that represent threats to the health of the body. (Craft and Kanter, 2002). Autoimmune disease refers to a broad range of over 80 acute, long-lasting diseases that affect nearly every organ in the body. (Wrong Diagnosis.com, 2000).

Innate immunity refers to antigen-nonspecific defence mechanisms that a host uses immediately or within several hours after exposure to an antigen. This is the immunity that you are born with, and is the initial response by the body to eliminate

The immune system is comprised of two responses: the adaptive immune response and the innate immune response. The first line of defence against invading organisms is classified as the innate immune response and the second line of defence and protection against re- exposure to the same pathogen is known as the adaptive immune response.

Have you ever wondered how your body works? Did you ever think about how your body defends itself from outside invaders? Remember the last time you were sick. Did you know how your body fought and killed the sickness? All these questions can be answered by learning about one of the most important systems in your body, the immune system.

For the immune system to able to keep us healthy it needs to be able to recognise what is a danger to our body and therefore needs to be removed, and what is safe. Proteins are used to do this. Pathogens have proteins on their surface called antigens, which activate the immune system. Our own cells also have surface proteins which the immune system recognises as part of the body and therefore doesn’t attack. (1)
