Immune System

The two major functions of the immune system is to prevent illnesses/diseases from coming and destroying one's body and also to keep your body strong and not get illnesses.

At a first consideration, one might argue that it depends on the disease and on the circumstances and there seems to be no single answer. However, if one looks further between the lines then an answer for the worst pathogen seems to appear.

Viruses, bacteria, and parasites can kill, mame and disfigure. Yes.

But now consider WHERE most of the deaths and misery occur and WHY the misery occurs and why the people can't get access to cures.

Could the worst pathogen of all be the greedy human? For example, humans that channel aid into money for arms or personal posessions. Humans that charge extortionate rents and cause misery for tennants and their families through poverty. Some might argue for the inclusion of internet gambling companies and loan sharks into this list. Greed that forces the poor into prostitution. Humans that oppose health care for the poor because "I'm all right jake". The human that will own several jets and yachts whilst the sweat shop workers starve or have to rake in rubbish dumps to find some scrappings of half rotted chicken left overs for their kids.

So perhaps it's not MRSA, AIDS or FLU or even rabies, but human greed, that is the worst pathogen of all.

Perhaps it kills more than all the diseases combined ?

(Scientist)

Yes. Older people are more susceptible to infection. There are many reasons for the same. There is usually malnourishment. There is usually psychological depression and anxiety. They do not care to take proper precautions and like.

The Innate Immune System

•Acts as the first line of defense

•Is nonspecific, meaning it tries to prevent everything from coming in

•Is nonadaptive

-does not have a memory

-will not learn to keep substances out even after repeated exposure

•Includes skin, fur, saliva, stomach acid and mucous

Where it is produced

The easy answer is the white blood cells but there are various types of white blood cells ( leucocytes) involved including cell eating defensive cells (phagocytes) called neutrophils which are very small but capable of engulfing several pieces of damaged tissue and bacteria. These are amongst the first cells to take action. Monocytes are immature as they leave blood vessels and enter tissues but they mature rapidly into active cells called macrophages (means big eater) which can consume up to 100 bacteria or similar sized cellular debris before its death occurs.

There are four types of antibodies that aid in immunity. The Lysins bind the antigens therefore causing them to disintegrate. The Agglutinins bind the antigens causing the micro-organisms to clump together. The Antitoxins bind the toxins therefore making them harmless to the body. The Opsonins bind the antigens on the outer surface.

It protects the body from viruses and bacteria.

Lysozymes

Plasma cells proliferate and produce antibodies against an antigen during humoral immunity.

To protect against polio.

Exposure to the Rh (or D) antigen. Most common in mothers who are Rh- who have a child that is Rh+. The mothers immune system will produce Rh antibodies and the blood cells of the NEXT Rh+ baby could be attacked during birth. Rh- mothers are given Rhogam to prevent this from happening. I know this is more than you asked for but every test question dealing with Rh asks something about this it is commonly called hemolytic disease of the newborn

One of the major functions of the immune system is to protect the body against harmful pathogens. It also functions to build up a defense system against any potential infections.

lymphocytes

Your own cells were created with certain "recognition" proteins on their cell membrane, which tells your immune system to ignore them when encountered. When this process fails, we see many "auto-immune" diseases like multiple sclerosis. It is also recently thought that asthma and diabetes may have some "auto-immune" components which tend to destroy pancreatic islet cells or epithelial cells in the bronchioles.

globulins are the proteins present in blood plasma..proteis constitutent 7to 8% blood plasma.other proteins are albumins and fibrinogen..

globulins are used for transportation and disease resistance..

The specific defense system, more commonly the immune system, is the second type of defense system within the body. It's purpose is to comprise a specific defense measure against a pathogen. The specific defense system is not made up of actual organ structures, but it is made up of billions of cells. Thus, the specific defense system is known as a functional system, as opposed to an organ system.

It is possible to refer to them as such but not exactly correct. After B cells are helped by TH1 cells, the B cells differentiates in to thousands of plasma cells. The plasma cells secrete antibody's that kill extracellular bacteria.

Phagocytes are very important components of our body's immunity (innate immunity). They are cells that can phagocytose foreign microbes (engulfing microbes by the cell membrane) and then they use enzymes to break down these foreign microbes. Phagocytes may also present the remnants of the microbe to a different type of cells (lymphocytes) to create a memory of that microbe in the body.

Lysozymes

To continue to replicate and exist, a flu virus must be in a host animal's cells. They can be grown in cultures (and eggs) for creating vaccines, but need a living host for long term activity and to "live".
