What are the cells that combine with foreign antigens and present them to t cells called?
Macrophages
How does a B cell tell the difference between an invader cell and a body cell?
Antigens work as bar-codes to help the immune system differentiate between body cells and pathogens. Normally the body will not attack its own cells, but is programmed to attack those with foreign antigens.
Do b cells destroy cancer cells?
No, cancer cells express self antigens, so your body cannot recognize it as foreign or dangerous.
The cell types that are most responsible for presenting foreign antigens together with surface antigens to specific receptors on the membrane of T lymphocytes are the macrophages and?
dendritic cells
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?
complement
What types of antigens are recognized by B cells?
Processed fragments of protein antigens displayed on surfaces of body cells.
What are the cells that combine with foreign antigens and present them to t cells called?
Macrophages
What typoes of cells produce antigens?
All cells produce antigens, or cell surface markers. The only question is whether the antigens are self antigens which means they belong in the body or they're foreign antigens which means they are an invading bacteria or virus (or a cancerous cell).
Specialized cells that attack foreign substances upon recognizing the foreign surface antigens are called?
T-lymphocytes
What is the function of MHC?
To bind to antigens for B and T cells to identify as self or foreign.
How does a B cell tell the difference between an invader cell and a body cell?
Antigens work as bar-codes to help the immune system differentiate between body cells and pathogens. Normally the body will not attack its own cells, but is programmed to attack those with foreign antigens.

The cell types that are most responsible for presenting foreign antigens together with surface antigens to specific receptors on the membrane of T lymphocytes are the macrophages and?
dendritic cells
Foreign antigens pressed into the plasma membrane are recognized by what?
helper T cells B cells so the answer is B for Plato users
What white blood cells are responsible for recognizing and destroying foreign antigens?
lymphocytes or A for Plato students
How does the thymus in the lymphatic system assist the immune system?
The thymus matures T lymphocytes (T cells) which identify foreign antigens. This is also where T cells that would be able to bond with self-antigens (would attack the bodies healthy cells) are weeded out and destroyed.
When the antibodies in the patient's serum attack antigens on the erythrocytes in donor blood this is known as?
When the antibodies in the patient's serum attack antigens on the erythrocytes in donor blood, this is known as red blood cell incompatibility. Patients should receive blood with the same ABO and Rh(D) classification. A and B are dissimilar antigens on the red cells. The immune system recognizes antigens as foreign. O cells do not have A or B antigens.
