Human Anatomy & Physiology: All About Blood 5
I created these quizzes to help me study for my A&P exams. This quiz is about blood typing.
Questions and Answers
- 1.
_______ are proteins that are found on the surfaces of the red blood cell membranes and are present at birth as a result of inheritance.
Explanation
Antigens are proteins that are present on the surfaces of red blood cell membranes and are inherited from birth. These antigens play a crucial role in determining an individual's blood type and can trigger an immune response if they are recognized as foreign by the immune system. The presence or absence of specific antigens determines the compatibility of blood transfusions and organ transplants.Rate this question:

_______ are dissolved in the plasma and begin to appear spontaneously, for unknown reasons at about ___ months after birth.
Explanation
Antibodies are dissolved in the plasma and begin to appear spontaneously, for unknown reasons at about 2-8 months after birth.Rate this question:

___________ involves identifying the antigens that are present on a person's red blood cells.
Explanation
Blood typing involves identifying the antigens that are present on a person's red blood cells. This is done by testing the blood sample with specific antibodies that react with the different antigens. By determining the presence or absence of certain antigens, blood typing can help determine a person's blood type, such as A, B, AB, or O. This information is crucial for blood transfusions and organ transplants to ensure compatibility and prevent adverse reactions.Rate this question:

________ refers to the clumping of red blood cells in response to a reaction between an antigen and an antibody.
- A.
Coagulation
- B.
Clotting
- C.
Aggregation
- D.
Agglutination
- E.
Retraction

- 5.
Today, it is known that the blood of the donor must be carefully matched with the blood of the recipient. If the blood is not compatible a _____________ will occur. This is a serious reaction in which the antibodies in the recipient's blood attack the foreign red blood cells in the blood transfusion causing them to agglutinate.
Correct Answer
transfusion reactionExplanation
When the blood of the donor is not compatible with the blood of the recipient, a transfusion reaction can occur. This is a serious reaction where the antibodies in the recipient's blood recognize the foreign red blood cells in the transfusion and attack them. As a result, the red blood cells clump together (agglutinate), leading to potential complications and harm to the recipient.Rate this question:
- 6.
Blood type A has ___ antigens on the red blood cells and _____ in the plasma
Correct Answer
A, anti-BExplanation
Blood type A has A antigens on the red blood cells and anti-B antibodies in the plasma. This means that individuals with blood type A have A antigens on the surface of their red blood cells, which can be recognized by antibodies in the plasma. These antibodies are called anti-B antibodies because they react with the B antigens found on the surface of red blood cells in individuals with blood type B. Therefore, if blood type A is mixed with blood type B, the anti-B antibodies in blood type A will react with the B antigens in blood type B, causing a potentially dangerous immune response.Rate this question:
- 7.
Blood type B has _____ antigens on red blood cells and _____ antibodies in the plasma.
Correct Answer
B, anti-AExplanation
Blood type B has B antigens on red blood cells and anti-A antibodies in the plasma. This means that individuals with blood type B have B antigens on the surface of their red blood cells, which can be recognized by antibodies in the plasma of individuals with blood type A. These antibodies will react with the A antigens, causing agglutination or clumping of the blood cells if blood from a person with blood type A is transfused to a person with blood type B.Rate this question:
- 8.
Type AB blood has ________ antigens on red blood cells and _____ antibodies in the plasma.
Correct Answer
A and B, noExplanation
Type AB blood has both A and B antigens on red blood cells, meaning it has both A and B markers on its surface. However, it does not have any antibodies against A or B antigens in the plasma. This is because individuals with type AB blood can receive blood from any type (A, B, AB, or O) without having an immune reaction, as their immune system does not produce antibodies against A or B antigens.Rate this question:
- 9.
Type O blood has ______ antigens on red blood cells and _________ antibodies in the plasma.
Correct Answer
no, anti-A and anti-BExplanation
Type O blood is known as the universal donor because it lacks A or B antigens on the surface of red blood cells. This means that it can be safely transfused to individuals with any blood type. However, individuals with type O blood have both anti-A and anti-B antibodies in their plasma, which can react with A or B antigens if transfused with the wrong blood type, leading to potentially life-threatening reactions.Rate this question:
- 10.
Human cells have _____ chromosomes in their nuclei. These are in pairs and one of the chromosomes in each pair is inherited from each parent.
- A.
52
- B.
48
- C.
46
- D.
44
- E.
50
Correct Answer
C. 46Explanation
Human cells have 46 chromosomes in their nuclei. These chromosomes are in pairs, with one chromosome from each pair inherited from each parent.Rate this question:

Genes for ABO blood groups are located on chromosome ____.
- A.
5
- B.
8
- C.
10
- D.
12
- E.
9
Correct Answer
E. 9Explanation
The correct answer is 9. The genes for ABO blood groups are located on chromosome 9. These genes determine the A, B, AB, or O blood type of an individual. The ABO blood group system is one of the most well-known and widely used blood typing systems in medicine.Rate this question:

_______ refers to the genetic makeup.
Correct Answer
GenotypeExplanation
Genotype refers to the genetic makeup of an organism, including all the genes and alleles present in its DNA. It is the complete set of genetic information that determines the traits and characteristics of an individual. The genotype can influence various aspects of an organism's phenotype, such as its physical appearance, behavior, and susceptibility to certain diseases. By studying the genotype, scientists can gain insights into the inheritance patterns and genetic variations within a population or species.Rate this question:
- 13.
________ refers to the physical or observable trait.
Correct Answer
PhenotypeExplanation
Phenotype refers to the physical or observable trait. This term is used to describe the characteristics or traits that can be observed or measured in an individual, such as eye color, height, or hair texture. It is influenced by both genetic factors and environmental factors. The phenotype is the result of the interaction between an individual's genotype (genetic makeup) and the environment in which they develop.Rate this question:

What is the blood type that is considered the universal recipient because it does not contain either anti-A or anti-B antibodies to react with a donor's blood?
- A.
Type A
- B.
Type B
- C.
Type AB
- D.
Type O
Correct Answer
C. Type ABExplanation
Type AB blood is considered the universal recipient because it does not contain either anti-A or anti-B antibodies to react with a donor's blood. This means that individuals with type AB blood can receive blood from any blood type without the risk of an immune response.Rate this question:
-
- 15.
Which blood type is considered the universal donor because it contains neither A or B antigens on red blood cells so it won't react with possible antibodies that might be present in the recipient's blood?
- A.
Type A
- B.
Type B
- C.
Type AB
- D.
Type O
Correct Answer
D. Type OExplanation
Type O blood does contain both anti-A and anti-B antibodies. If it is given to a person with blood type A, B or AB it should be transfused slowly to minimize the chance of an adverse reaction.Rate this question:
