has anti-A antibodies .

Type AB blood

has both A and B antigens on the red cells.

Which of the following is NOT a method of CO2 transport in the blood? Combined with hemoglobin Dissolved in the plasma As bicarbonate ions in the plasma Held in the depression of a red blood cell

held in the depression of a red blood cell

The function of plasmin is to: hydrolyze fibrin. activate factor XII. promote platelet plug formation. control osmotic pressure of the blood. promote the formation of plasma.

hydrolyze fibrin.

Aspirin inhibits platelet plug formation by: blocking the binding of platelets to collagen. interfering with the synthesis of prostaglandins. blocking the effects of serotonin. making the platelet surface less sticky. stimulating the release of heparin.

interfering with the synthesis of prostaglandins

neutrophil

When large quantities of blood are lost, erythrocytes must be replaced to restore: the body's ability to fight infection. oxygen-carrying capacity. thrombin levels. normal blood pH. iron levels.

oxygen-carrying capacity

During platelet plug formation, platelets begin to stick to: platelets stick to the exposed collagen fibers of injured vessels. thrombin is released from endothelial cells. vitamin K production increases. platelets multiply.

platelets stick to the exposed collagen fibers of injured vessels

reticulocyte

Which of the following is NOT a consequence of sickle-cell anemia? Red blood cells take on the sickle shape when oxygen levels are low. Sickle-shaped red blood cells can become lodged in capillaries. Tissue damage from decreased blood supply. Sickle-shaped red blood cells are less likely to rupture.

sickle-shaped red blood cells are less likely to rupture
