Immune System

This category is for questions about how our bodies identify and fight off disease, infection or pathogens through specialized cells, tissues and organs. The system that does this is called the immune system. It produces antibodies which recognize intruders and neutralizes potentially pathogenic organisms or substances.

Who is the pioneer of the smallpox vaccine?

Edward Anthony Jenner (17 May 1749 - 26 January 1823) was an English scientist who is widely credited as the pioneer of smallpox vaccine, and is sometimes referred to as the "Father of Immunology".

Are their people that are immune to this virus?

Scientists have discovered that there are certain individuals who appear to be genetically unable to reproduce the virus. There is something in the makeup of their blood cells which makes it impossible for the HIV virus to attach and reproduce. In essence, these individuals are immune because, from a biological point of view, the HIV virus cannot attack them.

How does the immune system help maintain homeostasis?

SERIOUSLY? if someone else got quest wrong, just erase it not make fun of them. ANYWAY the correct answer is:

it lets you know what's wrong with your body. It preforms certain operations to keep the body balanced out. It brings excess fluid to the bloodstream.

i hope that helped ^_^

oh and i looked up another answer and somone else got :

"Immune system in our body is such a vast subject running in volumes on which continuous research is going on…..

However it can be interestingly briefed as below:

1. Natural immunity : This is the immunity of the mother transmitted to the newborn in the uterus through placenta until its birth, and through the breast milk feeding after birth.

2. Acquired immunity : As the child after birth while growing into a man he will be acquiring some immunity or other for each and every disease/organism he is exposed, thus helping in the cure of the disease (with the help of the WBC circulating in our blood), and in developing resistance to prevent the same disease to attack second time.

3. Auto immunity : Here the body develops immunity to its own cells , tissues, organs etc. and starts rejecting them (Abnormal or let us call suicidal)!

4. immuno (gamma) globulins play a major role in developing the immune mechanism in our body. They act like military forces in protecting our body in preventing disease causing organisms to enter our body by forming similar structures like the organisms and stand before the targeted tissue (receptors), there by giving no scope to the organism to invade the tissue to cause the disease. Thus depending on the strength of these immuno globulins the disease is either made not to reoccur at all and driven away or aborted ; or made to affect with low intensity etc., when the White Blood Cells (WBC) circulating in our blood go and engulf and destroy the external organisms that have entered our body!

In this way there is a constant harmony maintained between the Body tissues, its immediate immune response and the White Blood Corpuscles (WBC) in protecting our body from invasion by external bacteria and viruses that are causing the disease and thus maintain a Homeostasis!

It is this lack of the Acquired Immune system that is responsible to cause AIDS (Acquired Immuno Deficiency Syndrome), where due to the total lack of this immune mechanism, the external organisms always gain an upper hand causing extensive uncontrollable disease there by resulting in death of the individual !"

What is the largest blood leukocyte?

That would be the macrophage the last stage of the Agranulocyte (without granules) Monocyte. A component of the reticuloendothelial system in humans, phagocytes are defensive cells that "eat" contaminants/invaders, working by envelopment and bioloigcal assault.

Protein that helps with immune system defense?

Proteins help form immunoglobulins, or antibodies, to fight infection ( 25 , 26 ). Antibodies are proteins in your blood that help protect your body from harmful invaders like bacteria and viruses. When these foreign invaders enter your cells, your body produces antibodies that tag them for elimination ( 27 ).

Do Pathogens can enter the body by way of air water and food?

Both, that is why we have four different kinds of isolation at the hospital. For example, tuberculosis is air borne so a mask is necessary. Joymaker RN

What does high lymphocyte and high platelet count mean?

Mean platelet volume is the size of the platelets. The higher the MPV the larger the platelet size and the lower the MPV the smaller the platelets. High MPV can cause a person to be at a higher risk for strokes and heart attacks. Low MPV can cause a person to be at risk for bleeding problems (too much bleeding that is slow to stop). There are some natural anti coagulants that help lower MPV blood like flax seed oil and fish oil.

How does inflammation work?

The diet in the developed world has skewed the intake of Omega 6--the inflammatory fat--in proportion to Omega 3--the un-inflammatory fat--from a natural 1:1 to as high as 20:1! This is why one sees so much supplementation here; because Omega 3 costs more, it has been depleted from the food supply.

What kind of cell can engulf bacteria or make antibodies?

Inside the human body, a particular type of white blood cell called a macrophage will engulf and digest bacteria.

What is the difference between a pathogen and a disease?

Pathogen is the agent or the culprit that causes a disease while the disease is the end result of what a pathogen did. Example: HIV virus is the pathogen while AIDS is the disease state that can result from high HIV viral load.

If the immune system is stronger are you protected against swine flu even if you have been in contact?

Generally speaking, you will be better equipped to fight off a viral infection if you have a strong immune system, but the only thing that will give you full protection is to have immunity developed from having had the same type of flu before, or from taking a vaccination against that specific flu strain.

An added aid for your body to use to help protect you from swine flu, would be use of the anti-viral medications that are being prescribed to help fight the influenza viruses, such as Tamiflu and Relenza.

(See information in the related questions below about how your body fights swine flu and about A-H1N1/09 Vaccines and other treatments for the Novel H1N1 Swine Flu.)

What would a pea size lump in the ear lobe be?

This is a common trigger point area. When the SCM's (sternocleidomastoid) muscles are extremely tight, this point under your ear will tighten up and form a lump. The muscle goes from the tip of the clavicle to the mastoid process under your ears. I use Merry Hempsters heat rub on the lumps and the muscles. This is common in people who sit and/or stand with their head stuck out (chicken neck) like me. I try to concentrate on standing with the top of my breastbone pointing straight to the sky. No slouching!
