Question 1

In the term lymphadenitis,the root aden means :
A)gland.
B)lymph.
C)inflammation.
D)duct.

Accepted Answer

The root "aden" means "gland," so lymphadenitis refers to inflammation of lymph glands.

Question 2

Which of the following is not a function of the lymphatic system?
A)transports proteins and fluids
B)protects the body against pathogens
C)produces thrombocytes
D)serves as a pathway for the absorption of fats

Accepted Answer

The lymphatic system's functions include transporting proteins and fluids, protecting the body against pathogens, and serving as a pathway for the absorption of fats. However, it does not produce thrombocytes (platelets), which are produced in bone marrow.

Question 3

In the term lymphedema,the suffix -edema means :
A)fluid.
B)swelling.
C)lymph.
D)globe.

Accepted Answer

The suffix -edema means swelling, which is a characteristic symptom of lymphedema.

Question 4

In the term hematocrit,the suffix -crit means :
A)to separate.
B)destruction.
C)loosen.
D)protein.

Accepted Answer

The suffix -crit comes from the Greek word kritēs which means to separate. Therefore, hematocrit refers to the percentage of red blood cells in a given volume of blood after it has been separated by centrifugation.

Question 5

What is the iron-containing pigment of red blood cells called?
A)globulin
B)prothrombin
C)hemoglobin
D)corpuscle

Accepted Answer

The iron-containing pigment of red blood cells is called hemoglobin. The other choices are not related to the function or composition of red blood cells.

Question 6

In the term anaphylaxis,the suffix -phylaxis means :
A)fusion.
B)protection.
C)growth.
D)against.

Accepted Answer

The suffix -phylaxis means protection, defense, or guard. Anaphylaxis is a severe and potentially life-threatening allergic reaction that involves a sudden immune system response to an allergen. Therefore, the term anaphylaxis implies an extreme protective response against a foreign substance.

Question 7

In the term erythropoietin,the root poiet means :
A)shape.
B)protein.
C)formation.
D)cell.

Accepted Answer

The root "poiet" comes from the Greek word "poiein" which means "to make" or "to form". Therefore, the correct choice is C) formation.

Question 8

In the term leukocyte,the combining form leuk/o means :
A)yellow.
B)blue.
C)white.
D)red.

Accepted Answer

The combining form leuk/o means white. Leukocyte refers to a white blood cell.

Question 9

The fluid part of the blood is called:
A)serum.
B)plasma.
C)lymph.
D)hemoglobin.

Accepted Answer

The fluid part of the blood is called plasma. Serum is similar to plasma, but it does not contain the clotting factors found in plasma. Lymph is a separate fluid that circulates through the lymphatic system. Hemoglobin is a protein found in red blood cells that helps transport oxygen.

Question 10

In the term hemochromatosis,the root chromat means :
A)green.
B)reddish-yellow.
C)color.
D)red.

Accepted Answer

The root "chromat" comes from the Greek word "chroma" which means color. Therefore, hemochromatosis (a condition where the body stores too much iron) literally means "too much color in the blood" as iron gives blood its red color.

Question 11

Excessive bleeding,bursting forth of blood is called:
A)hemorrhage.
B)hemophilia.
C)hemostasis.
D)hemophobia.

Accepted Answer

Excessive bleeding or bursting forth of blood is referred to as hemorrhage. Hemophilia is a genetic disorder that impairs the body's ability to clot blood. Hemostasis is the process where blood vessels are repaired and bleeding is stopped. Hemophobia is a fear or phobia of blood.

Question 12

A protein substance that is produced in the body in response to an invading foreign substance is called a/an:
A)antigen.
B)phagocyte.
C)platelet.
D)antibody.

Accepted Answer

Antibodies are proteins produced by the immune system in response to the presence of a foreign substance called an antigen. Antibodies bind to antigens and help to neutralize or eliminate them from the body. Phagocytes are white blood cells that engulf and destroy foreign substances, platelets are small blood cells that help with blood clotting.

Question 13

The medical term for a tumor of the thymus is:
A)thymitis.
B)thrombocyte.
C)thymoma.
D)thrombosis.

Accepted Answer

A tumor of the thymus is called a thymoma. Thymitis refers to inflammation of the thymus gland, thrombocyte refers to a blood cell responsible for blood clotting, and thrombosis refers to a blood clot within a blood vessel.

Question 14

A medical condition in which there are too many RBCs is:
A)anemia.
B)leukemia.
C)polycythemia.
D)septicemia.

Accepted Answer

Polycythemia is a condition where there is an excessive production of red blood cells (RBCs). Anemia is a condition where there are too few RBCs, leukemia is a type of cancer that affects blood cells, and septicemia is a potentially life-threatening infection caused by bacteria in the bloodstream.

Question 15

An abnormally large erythrocyte is called:
A)monocyte.
B)macrocyte.
C)microcyte.
D)phagocyte.

Accepted Answer

An abnormally large erythrocyte is called a macrocyte. A monocyte is a type of white blood cell, a microcyte is an abnormally small erythrocyte, and a phagocyte is a cell that engulfs and ingests foreign particles or cells.

Question 16

The clear,yellowish fluid that separates from the clot when blood clots is:
A)lymph.
B)serum.
C)plasma.
D)thrombin.

Accepted Answer

Serum is the clear, yellowish fluid that separates from the clot when blood clots. It does not contain the clotting factors found in plasma. Lymph is a clear fluid that circulates through the lymphatic system, and plasma is the liquid part of blood that contains clotting factors. Thrombin is an enzyme that helps in the clotting process.

Question 17

In the term monocyte,the prefix mono- means :
A)one.
B)many.
C)two.
D)double.

Accepted Answer

The prefix "mono-" means "one", so monocyte refers to a type of white blood cell that has one nucleus.

Question 18

Excessive amounts of sugar in the blood is called:
A)hypoglycemia.
B)hypercapnia.
C)hypercalcemia.
D)hyperglycemia.

Accepted Answer

Hyperglycemia refers to high levels of sugar in the blood, which can be caused by factors such as diabetes, stress, or certain medications. Hypoglycemia, on the other hand, refers to low levels of sugar in the blood, and can cause symptoms such as weakness, confusion, and seizures. Hypercapnia refers to high levels of carbon dioxide in the blood, while hypercalcemia refers to high levels of calcium in the blood.

Question 19

The life span of an erythrocyte is:
A)70-102 days.
B)80-120 days.
C)90-130 days.
D)120-160 days.

Accepted Answer

The life span of an erythrocyte, also known as a red blood cell, is approximately 80-120 days before being removed and broken down by the spleen and liver.

Question 20

A blood enzyme which causes clotting by forming fibrin is:
A)thromboplastin.
B)globulin.
C)heparin.
D)thrombin.

Accepted Answer

Thrombin is the blood enzyme responsible for clotting by converting fibrinogen to fibrin. Thromboplastin is important in initiating the clotting process by converting prothrombin to thrombin. Globulin refers to a group of proteins in blood plasma, and heparin is an anticoagulant that prevents clotting.
