- A.
Antigen
- B.
Antibody
Correct Answer
B. AntibodyExplanation
An antibody is an immunoglobulin that provides protection against most common infections. It is a glycoprotein that stimulates phagocytosis. Antibodies are produced by B cells in response to the presence of antigens in the body. They bind to specific antigens and mark them for destruction by immune cells, such as phagocytes. This immune response helps to eliminate pathogens and prevent further infection.Rate this question:

A person's blood type is determined by the presence or absence of specific antigen(s) on the surface of their red blood cells (RBCs).
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
A person's blood type is determined by the presence or absence of specific antigen(s) on the surface of their red blood cells (RBCs). This means that certain molecules, called antigens, are present on the surface of the red blood cells, and the combination of these antigens determines a person's blood type. This is why blood types can be classified into different groups, such as A, B, AB, and O, based on the presence or absence of these antigens. Therefore, the statement is true.Rate this question:

Hemolytic disease in the newborn results in a shortened life of the fetal and/or newborn RBCs because of the mother's sensitization to the fetal RBC antigens inherited from the father.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The explanation for the given correct answer is that hemolytic disease in the newborn occurs when the mother's immune system produces antibodies against the fetal red blood cells (RBCs) due to the presence of different RBC antigens inherited from the father. This immune response leads to the destruction of the fetal and/or newborn RBCs, resulting in a shortened lifespan for these cells. Therefore, the statement is true.Rate this question:

Sensitization of the mother's immune system to the fetus' RBCs stimulates the production of the immunoglobulin, _____ , that is transplacentally transferred to the fetus.
- A.
IgA
- B.
IgM
- C.
IgG
- D.
IgD
Correct Answer
C. IgGExplanation
During pregnancy, the mother's immune system may become sensitized to the fetus' red blood cells. This sensitization triggers the production of immunoglobulin G (IgG), which is then transferred across the placenta to the fetus. IgG is the only immunoglobulin that can cross the placenta and provide passive immunity to the developing fetus. It helps protect the fetus from infections and plays a crucial role in the immune response during pregnancy. IgA, IgM, and IgD do not cross the placenta as readily as IgG and have different functions within the immune system.Rate this question:
