What is a scientific word for foreign chemicals?
'Foreign' chemicals which get into the blood and provoke an immune response are called antigens.
A persons blood type depends on the presence or absence of certain proteins called?
A person's blood type depends on the presence or absence of certain proteins called antigens on the surface of red blood cells. These antigens determine whether a person's blood type is A, B, AB, or O.
What is the blood cell protein that elicits an immune reaction?
The protein that elicits an immune reaction in blood cells is called an antigen. Antigens are typically foreign substances that trigger an immune response when they are detected by the immune system.
Why do you think a person with blood type AB is universal recipient?
A and B are antigens that are on the surface of red blood cells. People have one, both, or none. If you don't naturally produce the antigen, your body's white blood cells will attack and destroy red blood cells that carry them. So if a person with type A blood is injected with type B blood, the body of that person will attack the type-B blood cells. A person with AB positive blood is a universal receiver, because they already produce all of the normal antigens present on red blood cells. So a AB+ person's body will not attack red blood cells that carry some, all, or none of the antigens. Likewise, O- is called the universal donor, because it lacks all antigens. So no one's body will recognize it as foreign.
What is the difference between blood types?
The red blood cells define the blood group you actually belong to. There are small markers known as antigens on the red cells surface, but they are so tiny that it cannot be viewed under a microscope. However, every person has different antigens but for identical twins. The antigens identify the blood types and are the key to match the transfusions as well that helps in avoiding serious complications. The blood group structure is defined as the ABO system. Another significant factor worth considering is the Rh system. All the blood groups have the possibility of having Rh antigens. Conversely, there are some who have it, while some do not have it. In case, the blood group belongs to Rh antigens, then they are Rh positive and a person having A blood group with Rh positive is recognized as A+. In case a person has A blood group with Rh negative, then it is A-. This is the same pattern followed for O, B or AB blood group as well. The Rh system duals the blood groups effectively so that the positive blood type does not get mixed with negative.
Substances that the body recognizes as foreign are called?
Antigens Antibodies neutralize these molecules.
Foreign invaders have proteins called?
Foreign invaders have proteins called antigens that are recognized by the immune system as non-self. This recognition triggers an immune response to eliminate the invading pathogen.
What are molecules that are foreign to your body called.?
Antigens Antibodies neutralize these molecules.
What is the foreign material called that stimulates the production of an antibody?
do you mean antigens? An antigen is any (foreign) substance that stimulates an immune reaction.
The foreign or nonself proteins that trigger immune responses are called?
An immune response is based on the ability to distinguish molecules that are part of the body ("self") from those that are not ("nonself," or foreign). Such molecules that can elicit an immune response are called antigens.
What can occur when antigens combine with the antibodies to M. Leprae in the bloodstream?
When the antigens combine with the antibodies to M. Leprae in the bloodstream, a reaction called erythema nodosum leprosum may occur, resulting in new lesions and peripheral nerve damage.
What white blood cells are responsible for recognizing and destroying foreign antigens?
The white blood cells responsible for recognizing and destroying foreign antigens are called lymphocytes. There are two main types of lymphocytes: B cells, which produce antibodies to tag antigens for destruction, and T cells, which directly attack and destroy cells that are infected or presenting foreign antigens.
Which are specific molecules that are recognized by the body as foreign and to which antibodies bind known as?
Specific molecules that are recognized by the body as foreign and to which antibodies bind are called antigens. Antigens can be proteins, carbohydrates, lipids, or nucleic acids that stimulate an immune response when they enter the body.
Specialized cells that attack foreign substances upon recognizing the foreign surface antigens are called?
These specialized cells are called immune cells, particularly T cells and B cells. They play a crucial role in the body's immune response by identifying and responding to foreign antigens to eliminate them and protect the body from infections.
Any foreign substance that enters the body and induces an immune response is called?
Antigen
What are molecules on the outer surface of a cell that identify it as long friend or for?
Molecules on the outer surface of a cell that identify it as "self" or "foreign" are called antigens. These antigens play a crucial role in the cell's ability to distinguish between its own cells and potentially harmful foreign cells. The recognition of self-antigens helps the immune system to tolerate the body's own cells while identifying and attacking foreign invaders.
What is a scientific word for foreign chemicals?
'Foreign' chemicals which get into the blood and provoke an immune response are called antigens.
