New cards

Red blood cell production is regulated by the hormone ________ which is mostly produced in the ________.

erythropoietin; kidneys

3
New cards

White blood cells that are increased in individuals with allergic reactions are the

eosinophils.

4
New cards

How does a treatment with anti-Rh antibodies (RhoGAM) prevent hemolytic disease of the newborn (HDN)?

It destroys fetal RBCs that enter the maternal circulation.

5
New cards

The function of hemoglobin is to

carry oxygen.

6
New cards

Define hemostasis. (Module 17.10A)

Hemostasis is the process of stopping bleeding.

7
New cards

Which of the following are the most abundant of the formed elements?

erythrocytes

8
New cards

A cancer involving neutrophils, eosinophils, or basophils is called a

myeloid leukemia.

9
New cards

Whole blood for testing in a clinical laboratory is usually collected from

a superficial vein.

10
New cards

When a person who lives at sea level vacations in the Rocky Mountains, you would expect

All of the answers are correct.

11
New cards

Which of the following is NOT a function of the blood?

generates body temperature

12
New cards

Platelets are pinched off from giant multinucleated cells in the bone marrow called

megakaryocytes.

13
New cards

Hemolytic disease of the newborn may result if

an Rh-negative mother carries an Rh-positive fetus.

14
New cards

Plasma is closest in ionic composition to

interstitial fluid.

15
New cards

A person's blood type is determined largely by the

presence of specific glycoproteins on the cell membrane.

16
New cards

Most of the iron that is removed from degraded hemoglobin is

recycled to red bone marrow.

17
New cards

During a bacterial infection you would expect to see increased numbers of

neutrophils

18
New cards

All of the following are components of the cardiovascular system except

lymph vessels.

19
New cards

The normal pH of blood is

slightly alkaline.

20
New cards

The combination of plasma and formed elements is called

whole blood.

21
New cards

Why can't a person with type A blood safely receive blood from a person with type B blood? (Module 17.7D)

A person with type A blood will have anti-B antibodies that will agglutinate with type B blood.

22
New cards

Which of the following is not a function of blood?

produce hormones

23
New cards

Which blood disorder involves a deficiency of Vitamin B12?

pernicious anemia

24
New cards

Formed elements make up about what percentage of blood?

45 percent

25
New cards

The process of red blood cell production is called

erythropoiesis.

26
New cards

People with type AB blood are considered the "universal recipient" for transfusions because

their blood lacks A or B antibodies.

27
New cards

The most numerous white blood cells in peripheral circulation are the

neutrophils.

28
New cards

Plasma composes about ________ percent of whole blood, and water composes ________ percent of the plasma volume.

55; 92

29
New cards

What is hematology? (Module 17.4A)

Hematology is the study of blood, blood-producing organs, and blood disorders.

30
New cards

RBCs typically live about 120 days. The main reason for this short lifespan in RBCs is their

lack of nucleus.

31
New cards

Platelets are

cytoplasmic fragments of large cells.

32
New cards

More than 95 percent of the protein in a red blood cell is

hemoglobin.

33
New cards

The percent fraction of formed elements relative to whole blood is the

hematocrit.

34
New cards

Identify the five types of white blood cells. (Module 17.9A)

neutrophils, eosinophils, basophils, monocytes, and lymphocytes

35
New cards

________ transport(s) oxygen and CO2 in the RBCs.

Hemoglobin molecules

36
New cards

Which of these descriptions best matches the term platelets?

adhere to collagen beneath endothelium

37
New cards

The disease sickle cell anemia is an example of what can happen if

a gene for adult hemoglobin is abnormal.

The average lifespan of a red blood cell is

4 months.

New cards

Platelets function in all of the following except

dissolving a formed clot.
