Exam 11: The Blood

Individuals with type-B blood display type-A antigens on their red blood cells.

____________________ is converted to ____________________ and then acts as an enzyme to activate fibrinogen.

What chemical signal released by healthy endothelial tissue prevents overgrowth of platelet plugs?

Anemia is a condition in which the oxygen-carrying capacity of the blood is increased.

Match each statement with the appropriate disorder. a.aplastic anemia b.pernicious anemia c.hemolytic anemia d.hemorrhagic anemia e.polycythemia f.leukemia g.neutrophilia h.sickle-cell anemia -Associated with prolonged exposure to low oxygen, such as at high altitude or with chronic lung disease

In the blood, the gamma globulin-producing leukocytes are more numerous than the leukocytes that differentiate to become macrophages.

A deficiency of vitamin B₁₂ is responsible for aplastic anemia.

Individuals with type-A blood have anti-B antibodies on their red blood cells.

Lymphocytes are the only granulocytes that make gamma globulins.

Exposed collagen in a damaged vessel

Match the cells with the correct characteristic. a.neutrophils b.eosinophils c.basophils d.monocytes e.lymphocytes f.thrombocytes -First phagocytes to arrive at site of bacterial invasion

To prevent serious blood transfusion reactions, a recipient's _______ (antigens/antibodies) must not react with the donor's _______ (antigens/antibodies).

Match each hemostasis step with the correct characteristic. a.Converts fibrinogen to fibrin b.When platelets come into contact with this substance in an injured vessel wall, it causes them to adhere and aggregate c.When activated, this substance digests the fibrin threads, causing dissolution of the clot d.Substance released by the platelet plug that causes more platelets to aggregate e.First step in hemostasis f.Forms the meshwork of the clot g.Plasma protein activated by factor X h.Second step in hemostasis i.Released from injured tissues; activates extrinsic clotting pathway j.Third step in hemostasis -Formation of a platelet plug

Match the cells with the correct characteristic. a.neutrophils b.eosinophils c.basophils d.monocytes e.lymphocytes f.thrombocytes -Least common leukocyte

The first step in hemostasis is the formation of a blood clot.

Which sequence is correct for plasma proteins, from greatest to lowest concentration? (Some items may have been omitted.)

Neutrophilia frequently accompanies bacterial infections.

Which type of anemia is caused by a genetic abnormality?

Individuals who have type-O blood

Blood is comprised of cellular elements and an extracellular matrix comprised primarily of water.What is the name of the blood's extracellular matrix?
