What else can I help you with?
Activated lymphocytes that produce antibodies are?
B lymphocytes are the cells that secrete the antibodies in response to infection in body.
Over the long term the body will produce antibodies immunoglobins if necessary to get rid of infection what kind of organic molecules are these antibodies?
Proteins.
What is the role b of the cell?
B-cells are lymphocytes that fight off extracellular infection and call other leukocytes (white blood cells; I.E. T-cells) to the site of infection. they also make antibodies.
What makes antibodies in the body?
Yes, by certain white cells in the blood. Some of these cells produce free floating antibodies while others present their antibodies on their surface receptors. These different systems fight infection by different kinds of organisms.
Is a substance that causes the release of antibodies that often produce an allergic reaction?
No, an allergic reaction is typically caused by a release of histamines from the eosinophils. Antibodies are produced by lymphocytes in response to a bacterial infection.
Why does passive immunity usually not last for long?
When you have immunity, your body has antibodies against a foreign organisms (i.e. bacteria and virus) . Usually this is achieved by exposure to these organisms. That is: 1. you get an infection (or vaccination with inactive parts of a bacteria or virus), 2.your body defeats the invader, 3. some of the cells in your body "remember" which antibodies they produced , 4. next time you are exposed to the same foreign organism, these cells quickly produce antibodies so you won´t get ill (i.e. you are immune) When you have passive immunity, it usually is due to a vaccination with antibodies. Your body hasn´t produced the antibodies on its own. So once the antibodies become too old and inactive, you are not immune any longer, and when you encounter the foreign organism again, it will be like a novel infection, because it has no memory cells, which can respond quickly.
What does your body produce when it feels threatened with germs?
When your body feels threatened by germs, it produces white blood cells, antibodies, and cytokines as part of your immune response to help fight off the infection.
A function of the blood that involves circulating antibodies to combat infection?
One of the function of the blood is to circulate antibodies to combat infection.
Antibodies are produced to counter infection?
No
Why does passive immunity usually not last for very long?
When you have immunity, your body has antibodies against a foreign organisms (i.e. bacteria and virus) . Usually this is achieved by exposure to these organisms. That is: 1. you get an infection (or vaccination with inactive parts of a bacteria or virus), 2.your body defeats the invader, 3. some of the cells in your body "remember" which antibodies they produced , 4. next time you are exposed to the same foreign organism, these cells quickly produce antibodies so you won´t get ill (i.e. you are immune) When you have passive immunity, it usually is due to a vaccination with antibodies.

So once the antibodies become too old and inactive, you are not immune any longer, and when you encounter the foreign organism again, it will be like a novel infection, because it has no memory cells, which can respond quickly.
What do white blood cells produce prevent infection?
White blood cells produce antibodies, which are proteins that help identify and neutralize harmful pathogens like bacteria and viruses. They also produce cytokines, which are signaling molecules that help regulate immune responses and coordinate the body's defenses against infection.
The injection of a killed or weakened virus into a person so that they will produce antibodies and thus be protected from future infection by the virus is called?
This is called vaccination. The process helps the immune system recognize and remember the virus, so if the person is exposed to the virus in the future, their immune system can quickly produce the necessary antibodies to fight off the infection.
