The Human Body Is A Complex System, Embedded With Defense

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.

One defence mechanism of the human body is that when a person gets ill or is infected the person will get a fever, this is a method of notifying the person. This is a bodily defence mechanism produced by the immune system, its main purpose is to make it difficult for the virus to multiply prepare for the virus. The body’s pH level will also change to make it less optimal for the virus. The immune system’s mechanism will change depending on the body’s condition. If the body gets cut the immune system will causes inflammation, this will cause red blood cells to come to the

One health condition that affects people is Coeliac Disease; this is intolerance to the protein ‘gluten’ which is found in wheat, barley and rye. When coming into contact with gluten the body produces antibodies which then attack the lining of the bowel. This then affects the body’s ability to absorb nutrients from food and can even lead to

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

Celiac disease is seen in about 1-2% of the population, with a 2:1 woman to men ratio (Lisa Ring Jacobsson, 2011). I choose this topic because celiac disease and gluten-free diets seem to be on the rise. In the past, the diet and lifestyle changes for people with celiac disease was very challenging, but in recent years there has been an increase in the amount of people being diagnosed with celiac disease. There is much more information out there about these special diets. Life has become much easier for those with celiac

Celiac disease is an autoimmune disease triggered by ingestion, of gluten-containing foods. The disease results from inappropriate T cells immune response against gliadin in genetically predisposed people. Individuals with this disorder have high levels of antibodies to a variety of antigens. The resulting immune response produces a strong inflammatory reaction that results in loss of absorptive villi from the small intestine. After the subsequent lesions are widespread, they may weaken absorption of macronutrients and micronutrients. Small bowel involvement

Adaptive immunity (p.446): The body’s ability to recognize and defend itself against distinct invaders and their products.

Our bodies were specifically designed to fight off diseases organically through the use of our immune system. When an antigen enters our bodies, our immune system immediately acknowledges its presence and produces antibodies to fight off the foreign organism. The antibodies will search for the disease organism and will dismantle it when found. The next time the body comes in contact with

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

As described by the Centers for Disease Control, chronic disease is the leading cause of death and disability in the United States. A The body is so well designed in some areas yet so poorly designed in others. Why has selection left us so vulnerable to disease? (Nesse, 2005.) Cancer, Diabetes, Cardio vascular,and Respiratory disease. (Infectious and Chronic Disease, 2015.) The immune system is the first line of defense against diseases and infections it a system of organs, tissue cells, and cell products such as antibodies. These antibodies neutralize potentially pathogenic organisms or substances. Signs of our immune system at work are coughing, fever, pain, nausea, vomiting, anxiety and fatigue; these are not abnormalities yet people seek medical help. The presence of these symptoms are fighting mechanisms of our immune system, thus being beneficial since they are aversive and are not themselves problems but a solution. The evolution significance of a disease like sickle cell, creates an immunity to malaria. “Sickle Cell Anemia, as long as carried heterozygous (AS), serve as an effective preventable took against the largest infectious disease killer in the world.” (Understanding our

Celiac disease is an inherited autoimmune digestive disorder that damages the hair-like structures (villi) on the lining of the small intestine. This hampers the absorption of nutrients into the bloodstream and leads to malnourishment. Celiac disease is the world’s most common genetic autoimmune disorder, affecting three million Americans, or about 1 in 141 people.

The unable to be harmed response on a person's body is how the body recognizes foreign bacteria, viruses and substances that may appear harmful to the body and defends itself by responding to the germs that the body tries to fight these have. The way it recognizes this germs that the body tries to fight is by already recognizing the proteins that have germs that the body tries to fight that already exist in the body that are not harmful. When the unable to be harmed response

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).

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

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)
