What react to something foreign in the body such as germs bacteria and viruses?
The white blood cells react to recognise, engulf and destroy the invading cells. There arw also lymphocytes and T-Cells and B-Cells which are activated with sensors so that Attatch to specific antigens. The T-Cells tell the B-Cell what shape antibody they need to attatch to the antigen on the invading cell. When all teh antigens on the invadingcell are sruck to a antibody the cell has been engulfed and destroyed. The cells also make copies(memory cells) of the antigens so that the will recognise and react fast as they already have the right antibodies prepared. However - some virus' etc mutate (such as flu) so when this invades a second timethe antigens are different and the body doesn't recognise it and has to behin the process from start.
What is the introduction of altered antigens to produce an immune response?
Introduction of altered antigens involves exposing the immune system to modified versions of antigens to trigger an immune response without causing disease. This approach can be used in vaccine development to stimulate immune memory and protection against specific pathogens or diseases. Altered antigens can include weakened or inactivated forms of pathogens, as well as genetically engineered antigens.
Why does blood agglutinate?
Leukoagglutination is extremely rare in health individuals and is far more common in those suffering from infections, sepsis, lymphoproliferative disorders, alcoholic liver disease, hemophilia, and autoimmune diseases.
What kills invading cells by drilling a hole in cell membranes?
Perforin, a protein released by cytotoxic T cells and natural killer cells, forms pores in the cell membranes of invading cells. This disruption leads to osmotic imbalance, cell death, and elimination of the invading cell.
what is the definition for thrombus?
A thrombus is a blood clot that forms in the circulatory system and remains where it forms rather than circulating in the blood.
Why is blood group identification not required while transfusing serum?
The serum is a cell free fluid which forms when the blood has clotted and the thombus has separated from it.Since the blood group deciding antigens are present on the RBC's which are not present on the serum .Hence,it can be transcribed to anyone without the need of blood testing.

What is present in a vaccine to cause white blood cells to respond by producing anti bodies?
Vaccines typically contain antigens, which are components that resemble disease-causing microorganisms. These antigens can be weakened or killed forms of the pathogen, pieces of it (like proteins), or genetic material that instructs cells to produce the antigen. When introduced into the body, these antigens stimulate the immune system, prompting white blood cells to produce antibodies specifically designed to target and neutralize the pathogen if encountered in the future.

What is a fight against a government?
A fight against the government can come in several forms. A couple of these forms are, a petition, a rally, or a protest.
The group of proteins that normally circulate in the blood in an inactive form and are activated by contact with nonspecific antigens such as foreign blood cells or bacteria?
These proteins are part of the complement system, which forms a crucial part of the immune response. Once activated, the complement proteins can lead to the destruction of pathogens through processes such as opsonization, inflammation, and cell lysis.

Does one blood test detect all forms of arthritis?
no,one blood test can not detect all forms of arthritis
What works to clot blood?
it is a dinosaur thatoughs up blood and forms a blood clot
What deactivates antigens?
Antigens can be deactivated by various mechanisms, including neutralization by antibodies, which bind to the antigen and prevent it from interacting with host cells. Other processes include enzymatic degradation, where enzymes break down the antigen, and the action of immune cells that engulf and destroy the antigen. Additionally, vaccines can introduce harmless forms of antigens that train the immune system to recognize and deactivate the real pathogens effectively.
