has a total volume of approximately 5 liters
Blood
The major component of plasma is __________.
water
The process of blood cell production is called __________.
hematopoiesis
All of the formed elements of the blood are formed from a single population of cells called __________.
hemocytoblasts
The biconcave shape of red blood cells
increases the surface area of the red blood cell.
makes it easier for gases to move into and out of the cell.
allows for bending or folding of the cell.
enables it to pass through small blood vessels more easily.

In contrast to red blood cells, leukocytes
can leave the blood and move by amoeboid movement through tissues.
Which of these leukocytes is NOT correctly matched with its function or description?
Monocytes—Become macrophages.
Lymphocytes—Important in the immune response.
Basophils—Synthesize or produce antibodies.
Eosinophils—Involved in destroying certain worm parasites.
Neutrophils—Phagocytize microorganisms and other foreign substances.
Basophils—Synthesize or produce antibodies.
__________ release histamine and heparin.
Basophils
__________ perform phagocytosis, especially when out of the blood and in tissues.
Monocytes
__________ are the largest of the leukocytes.
Monocytes
Clotting factor activation can start with
the contact of clotting factors with connective tissue.
results in platelets sticking to collagen exposed by blood vessel damage.
is mediated through von Willebrand factor.
causes the activation of the platelets.
allows for the platelets to change shape and release chemicals.
Platelet adhesion
play an important role in hemostasis.
Platelets
The healing process after clot formation involves
clot retraction.
repair of the damaged vessel by fibroblasts.
repair of the wound by division of epithelial cells.
conversion of plasminogen to plasmin.

conversion of plasminogen to plasmin.
Which of the following would inhibit the activation of platelets or the formation of the platelet plug?
Aspirin (which inhibits the synthesis of prostaglandins)
Which of these statements concerning ABO blood types is correct?
Persons with type O blood have been called universal donors.
Persons with type B blood who receive type A blood would have a transfusion reaction.
To reduce the likelihood of a transfusion reaction, all possible blood groups should be correctly typed.
Antibodies in the blood of the donor can react with the antigens in the blood of the recipient.
