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.

Which are there more of neutrophils eosinophils basophils lymphocytes or monocytes?
I know neutrophils are most numerous, then eosinophils, and basophils are least numerous. I don't know where on the continuum monocytes and lymphocytes lie.
What is the life span of antibodies and antigens?
Since the antibodies are a part of WBC's they ought to have a life equal to the WBC's
Where do B cells and T cells originate?
They both originate in the red bone marrow. B lymphocytes mature there. T lymphocytes mature in the thymus gland.
Who developed the culture plate method of identify pathogens?
Rober Kock developed the culture plate method to identify pathogens.
How you would have to live if your immune system did not protect you from bacteria?
You wouldn't live. You wouldn't even get "sick". Without any immune system at all, your body would just rot as the bacteria and fungi ate it.
What is the importance of immunology to public health?
The immune system protects the body from disease by attacking anything foreign to it. The redness and swelling around a cut or scratch is your immune system at work, bringing more blood to the area and creating heat to fend off invading bacteria which cause infection, or to the site of a splinter where pus may form to push the splinter out. People with organ transplants have to take anti-rejection drugs because the body's immune system "sees" it as a foreign object. People with AIDS (Acquired Immune Deficiency Syndrome) often succumb to pneumonia or other opportunistic diseases because their immune systems are "deficient" and the disease also attacks the cells that fight infection. Lupus is a disease of the immune system; Multiple Sclerosis may be an immune system disease along with Lou Gherig's disease (ALS: Amylotropic Lateral Sclerosis). These are so-called "auto-immune" diseases, like AIDS, where the body's immune system attacks its own body.

It depends on the type of vaccine that gets introduced into the blood and circulatory system by the intravenous (IV) route. Vaccines are typically not intended for that method of administration.

If you believe this has happened, you should contact a medical professional for advice in your specific circumstances without delay.
The flu vaccines are not intended for this method of delivery and you should seek urgent medical attention if that route was used for your influenza vaccine.
How is the immune system interdependent on the cardiovascular system?
1. From a cardiovascular point of view, current medical focus is on the effects of chronic inflammation on vascular health. It is known that patients with chronic disease, esp. inflammatory disease, have higher risk of CV disease. Certain medications that have a immune modulating effect have been shown to lower CV risk. One of the main ideas is that inflammation has an adverse effect on blood vessel intima, leading to higher risk of artherosclerotic disease.
2. From an immune-system point of view... this is even more complex. Immune modulators released in all sorts of circumstances (from stress, to sepsis) have effects on the CV system, with wide ranges from inotropic, chronotropic, as well as vasodilative effects.
How do pathogens enter the body through contaminated food and drink?
the virus can be spread to food through someone not washing their hands when preparing food or it hanging in the air and landing on it, we cannot see the virus so we might not realise it is there, we then take the food and eat it, passing the virus through with the food, inhaling it and eating it, causing the virus to spread through the body causing us to get the virus that was on the food.
