A)Thrombopoiesis
B)Phagocytosis
C)Erythropoiesis
D)Diapedesis

Answer 1

A)Hematology
B)Diapedesis
C)Hemostasis
D)Thrombus

Answer 2

C
Hemostasis is a term used to describe the clotting process immediately following blood vessel injury.

Question 3

Hematology is the study of the formed elements of the blood.

Answer 3

True
Other areas of the laboratory study the chemicals dissolved in the liquid portion of the blood, the clotting properties of the blood specimens, or other properties of the blood. Hematology focuses on the formed elements (cells) present in the bloodstream.

A)Lymphoid erythrocyte
B)Reticulocyte
C)Atypical thrombocyte
D)Leukocyte

Question 8

Where in the body do most of the white blood cells perform their functions?

A)In the tissues of the body
B)Within the vessels of the body
C)Within the red blood cells
D)Within the bone marrow

Question 9

Question 10

What attaches to the hemoglobin of red blood cells to travel to the tissues of the body?

A)Reticulum
B)Oxygen
C)Antibodies
D)None of the above

Question 11

Question 16

Which of these terms is not related to platelets?

A)Phagocytosis
B)Thrombus

C)Femur
D)Fibula

Question 19

Granular and agranular are categories into which leukocytes are separated. This separation is determined by the presence or absence of cytoplasmic granules.

Question 20

What is contained in the cytoplasmic granules of the granular white blood cells?

A)Digestive enzymes
B)Chemicals that contribute to the destruction of invaders
C)Platelets
D)A and B

Question 21

____________is a chemical present in the granules of basophils that makes blood vessel walls more permeable.

Question 22

White blood cells without granules present in their cytoplasm (such as lymphocytes) are known as ____________white cells.Short Answer

Question 23
