How The Body 's Health Defenses Or Immunity?

Our immune systems are amazing things. They create proteins to fight disease, which are known as antibodies. These antibodies try to battle it out against the antigens. Once our immune system creates certain antibodies, they’ll recognize the same intruders again and protect our bodies automatically year in year out.

Stress And The Immune System The immune system is a very important part of our bodily functions as its main function is to protect the body against millions of antigens, which attack our cells and try to reproduce viruses and diseases. The immune system can protect the body in three different ways, in which are: 1. It creates a barrier that prevents the antigens from initially entering the body. 2.

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.

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

The main function of the immune system is to protect the body from infectious agents such as viruses and other toxins. The immune system can fail us in two ways-either by becoming under-vigilant, letting infections enter the body, or over-vigilant, so that it is the immune system itself, rather than an infectious agent that causes illness.

Our immune system is taught to protect our body from diseases. The natural immune systems have protein and are more aware

The reason it is so important to fight against diseases is because a person’s body becomes immune to certain pathogens due to cells in your body called lymphocytes. The pathogens help fight off the diseases. Then antigens are a part of a pathogen and

The immune system is consisted of cells and tissues throughout the whole body. They work together to defend your body from any types of invasion and infections. Problems with the immune system can cause the immune system to mistaken the healthy body cells as invaders and will repeatedly attack the cells; this is known as an autoimmune disease. An example of this disease is the Hashimoto’s thyroiditis, where the immune systems mistakenly recognizes the thyroid cells as invaders and attack the thyroid.

A primary role of the immune system is fighting off harmful bacteria and viruses. However, recent studies have revealed additional roles of immune cells in other important host functions, such as controlling body weight.

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).

The body has two immune systems: the innate immune system and the adaptive immune system.

Normally the body is protected by the immune system. When the immune system detects an unwelcome visitor such as fungi, bacteria and or viruses

These normal microbes that are constantly living with us help to “protect us from becoming infected with the harmful microbes” (1). The amount of normal microbe cells is ten times greater than the amount of cells that make up the human body. Every day, every minute, every second, microbes are working hard to protect our bodies from becoming infected (1).

Our immune system is the second most complex system in our body. It is made up of organs, cells and proteins that work together to protect our bodies from harmful bacteria, viruses or other microorganisms that can cause diseases. Usually we don’t notice our immune system defending us against pathogens, but if the pathogen (harmful microorganism) is aggressive or if our body hasn’t ever come into contact with it, we can get sick. The jobs of our immune system are to recognise pathogens, as well as neutralise and remove them from our body. Our immune system also has to fight our own cells if they have changed due to an illness, for example, cancer. (1)
