- B.
NK cells
- C.
B cells
- D.
T helper cells
Correct Answer
C. B cellsExplanation
B cells are a type of lymphocyte that differentiate into plasma cells and memory cells. Plasma cells are responsible for producing antibodies, which are proteins that help to neutralize pathogens and foreign substances in the body. Memory cells, on the other hand, "remember" the specific antigens encountered by the immune system, allowing for a faster and more effective immune response upon subsequent exposure to the same antigen. This process is part of the humoral immune response, which involves the production of antibodies to fight off infections. T cells, NK cells, and T helper cells have different roles in the immune system and do not directly produce antibodies.Rate this question:

Which of the following nonspecific immunity mechanisms involves the process of certain cells engulfing and destroying microorganisms and cellular debris?
- A.
Inflammation
- B.
Intact skin and mucous membranes
- C.
Normal flora
- D.
Phagocytosis
Correct Answer
D. pHagocytosisExplanation
Phagocytosis is a nonspecific immunity mechanism that involves certain cells engulfing and destroying microorganisms and cellular debris. During phagocytosis, specialized cells such as macrophages and neutrophils recognize and engulf foreign particles or pathogens. These cells then break down and destroy the engulfed material using enzymes and other antimicrobial substances. This process helps to eliminate harmful microorganisms and cellular debris from the body, contributing to the body's defense against infections and maintaining overall health.Rate this question:

Which of the five types of antibodies are involved in allergic reactions?
- A.
IgE
- B.
IgM
- C.
IgA
- D.
IgG
Correct Answer
A. IgEExplanation
IgE antibodies are involved in allergic reactions. IgE antibodies are produced by the immune system in response to allergens, such as pollen, pet dander, or certain foods. When a person with allergies is exposed to these allergens, IgE antibodies bind to mast cells and basophils, triggering the release of histamine and other chemicals. This immune response leads to the symptoms of an allergic reaction, such as sneezing, itching, and swelling. IgM, IgA, and IgG antibodies are not typically involved in allergic reactions.Rate this question:

Pregnancy testing is based upon detection of ____ hormone.
- A.
FSH
- B.
LH
- C.
HCG
- D.
TEH
Correct Answer
C. HCGExplanation
Pregnancy testing is based upon detection of HCG hormone. HCG, also known as human chorionic gonadotropin, is a hormone that is produced by the placenta during pregnancy. It can be detected in a woman's urine or blood, indicating the presence of pregnancy. FSH (follicle-stimulating hormone) and LH (luteinizing hormone) are involved in the regulation of the menstrual cycle and ovulation, but they are not specific to pregnancy. TEH is not a hormone related to pregnancy testing.Rate this question:
