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.

What is considered a lymphocyte count?
Asked by Wiki User
What about a range of 22.2-43.6% as a normal range for lymphocytes, and the number is 47.6%, would this be considered abnormally high?
What is the second line defense?
Asked by Wiki User
The second line of defence is the non specific, it includes antimicrobial proteins, phagocytes and other cells.
- In this state to inhibit spread of invader through out the body.
-Inflamation, is its hallmark and most important mechanism.
Is death by starvation a painless death or a painful death?
Asked by Wiki User
it is a slow painful death
What can kill you faster a pathogen or poison?
Asked by Wiki User
answ2. Some poisons such as cyanide are near instantaneous. And some snake venom, but not quite instantaneous.
Pathogens need time to multiply in the host, produce infection products, and then kill. Several hours at the least, several days more commonly.
You know, I'm not entirely sure...
Why don't you test it out and then come back and tell us the answer.
What animal is immune to all known diseases?
Asked by Wiki User
It is believed that sharks are immune to almost all diseases; they rarely get sick. However, no animal is immune all disease. A disease is technically defined as any deviation from normal, so even a broken bone could be considered a "disease". As for viral/bacterial diseases, no animal is immune to all diseases of that or any other type. Every animal is susceptible to something.
What vitamin helps the nervous and immune system systems function efficiently?

Which vitamin helps the nervous and immune system function efficiently?

Vitamin B6
List two lines of nonspecific defense mechanisms with examples of each?
Asked by Wiki User
First of all, you might want to spell DEFENSE correctly.
What occurs during a primary immune response and secondary immune response?
Asked by Chichismithgp9871
The secondary immune response occurs after an antigen that has already been encountered reappears.
For example, if someone had recovered from the flu and later encounters the
same strain of that virus, antibodies that were made specifically for that antigen will rise dramatically with almost no lag perod.
Can you die without an immune system?
Asked by Wiki User
Without an immune system you are unable to fight off the most minor infections which will only get worse. That is essentially the reason people die from AIDS, they are so immunosuppressed that they succumb to infections that a healthy immune system could handle with ease.
Under what conditions might a person with Rh-blood develop Rh antibodies?
Asked by Wiki User
The first time an Rh- patient receives blood from an Rh+ donor, the Rh- patient will develop Rh agglutinins (agglutinins=antibodies) in the blood plasma. If the patient receives another Rh+ donation, it will cause agglutination, or clumping of the blood. The red blood cell membranes become leaky and hemoglobin pours into the blood. A possible cause is kidney failure due to excess hemoglobin at filtration sites.
Which of these is the human body's first line of defense against invading pathogens such as bacteria and viruses?
Asked by Wiki User
skin and mucous membranes
What things in the body kill viruses?
Asked by Wiki User
Antibodies are what our bodies use to block the action of viruses, however, since a virus particle is not really a living thing, it is not able to be killed. It is made inert or inactive by the antibodies our immune system produces that block the entry of the virus into our cells.
Antibodies are produced by?
Asked by Wiki User
Activated B cells, called plasma cells, are responsible for producing antibodies
Which antibodies can cross placental barrier?
Asked by Wiki User
IgG is the only antibody small enough to cross he placenta.
Is the function of leukocytes blood coagulation?
Asked by Wiki User
False- the leukocytes participate in protecting the body from infection; Coagulation is a complex process by which blood forms clots. ex: if you cut or stick yourself and blood begin to flow, immediately the blood forms a kind of thickness (like a film coating on the outside) and the blood begins to slow down, this forms a clot. The platelets immediately forms a plug as you will at the site.
The proteins in the blood is called the coagulation factor or the clotting factors to stop the blood from flowing more as the plug gets strong as it stops the blood.
So in otherwords, no it is not the function of the leukocytes it protects inside from foreign objects
Hope I explained it in a way you catch what its meaning.
Can your immune system shut down?
Asked by Wiki User
Yes, when you have AIDS your body is turning all attention to fighting the disese and in turn weakens your immune system and leaves you liable to other illnesses. With aids the common cold can kill you
How does your immune system protect you from bubonic plague?
Asked by Wiki User
it slows down infection by small amounts, your immune system can defend depending on how much white blood cells, high amounts reduces how quickly it infects. your immune system can eliminate it with the help of anti-botics.
How do antibodies react to antigens?
Asked by Wiki User
Type B antibodies react to type B antigens by begining to clump together, and the clumps may block blood vessels.
