Each of the following occurs when blood clots after a cut EXCEPT _______.
- thrombin converts fibrin into fibrinogen
- fibrin filaments trap cells to produce a clot
- platelets release clotting factor
- thromboplastin converts prothrombin into thrombin

Fragments of megakaryocytes that rupture into pieces and are responsible for clotting are called _______.
Neutrophils, eosinophils, and basophils are alike in that they _______.
The largest of all the white blood cells (WBCs) is the _______.
Which of the following terms is unrelated to the others?

Which of the following is a hereditary bleeding disorder, commonly called the "bleeder's disease"?
The doctor sticks your finger, takes some blood, and does a WBC count. The count (12,500 cells/mm3) indicates leukocytosis. What could you conclude?
It is a high WBC count, indicating a bacterial or viral infection.
What is the most numerous type of white blood cell, and an active phagocyte that increases rapidly during acute infections?
The process by which white blood cells move into and out of the blood vessels is called _______.
The rapid sequence of vascular spasms, platelet plug formation, and coagulation is known as _______.
While blood typing, the sample is mixed with anti-A serum and anti-B serum. There is no agglutination. You could conclude that _______.
the sample is type O
Blood is a complex _______ tissue and is the only _______ tissue in the body.
The living cells and cell fragments in blood are called the _______ elements and include erythrocytes, leukocytes, and _______.
Composed of approximately 90 percent water, over 100 different substances are dissolved in this straw-colored fluid called _______.
The molecule most responsible for carrying oxygen in blood is known as _______.
Accounting for about 1 percent of total blood volume, _______ form a protective, movable army to defend the body against bacteria, viruses, parasites, and tumor cells.
All formed elements arise from a single type of stem cell named a _______.
Hemostasis, involving three major phases including vascular spasms, platelet plug formation, and blood clotting, is called _______.
The meshwork structure of a proper clot is due largely to the _______ threads that trap the red blood cells.
Any substance the body deems as foreign is an _______ and the response molecules that react are called _______.
If a person has type AB blood, then that person can receive blood from which type donors?
people with types AB, A, B, or O
What are 3 types of formed elements in the blood?
Red blood cells, white blood cells, and platelets
What is plasma?
90% water; liquid part of the blood
Explain the process of blood clotting
Blood clots within 3-6 minutes; the triggering factors are rapidly inactivated to prevent widespread clotting. The endothelium regenerates & the clot is broken down.
Explain the ABO blood groups
They're base on type A or B; absence of both antigens results in type O blood. Presence of both A and B results in AB blood type.
Explain the difference between ABO blood groups and Rh-
Unlike the antibodies of the ABO system, anti-Rh antibodies are not automatically formed and present in the blood of Rh- individuals.
What are blood transfusions?
The process of transferring the blood of a person into the veins of another
Percentage of WBC: 1-4%
Role: Kill parasitic worms by deluging them with digestive enzymes; play a complex role in allergy attacks
Percentage of WBC: 1%
Role: Release histamine at sites of inflammation; contain heparin
Percentage or WBC- 20-45%
Role: Part of the immune system; one group produces antibodies; other group involved in graft rejection, fighting tumors and viruses, via direct cell attack
Percentage of WBC: 4-8%
Role: Active phagocytes that become macrophages in the tissues; long-term "cleanup team"; increase in number during chronic infections such as tuberculosis
Percentage of WBC: 40-70%
Role: Active phagocytes; number increases rapidly during short-term or acute infections
Role: Needed for normal blood clotting; initiate clotting cascade by clinging to torn area
Role: Transport oxygen bound to hemoglobin molecules; also transport small amount of carbon dioxide
Blood cell formation; occurs in red bone marrow or myeloid tissue
The hormone that controls the rate of erythrocyte production
Stem cells that give rise to all the formed elements of the blood
Stoppage of bleeding
