Which of the following are NOT formed elements of blood?

Globulins.

The intrinsic mechanism of blood clotting is initiated when platelets release

Hageman factor (factor XII).

During leukopoiesis, which of the following cells become mature granulocytes?

Identify the blood type.

Type B +

Which individuals are called the "universal donors"?

Type O

Identify the blood type

Type O-

Which of the following nutrients is NOT required for erythropoiesis?

Vitamin D

The antigens that determine the blood types are called

agglutinogens

When iron is released into the blood stream, it binds to ______________, a plasma protein.

transferrin

_______________ are the rarest leucocytes.

basophils

The most effective defense against bleeding is

coagulation (blood clotting).

In hemostasis, during the phase of platelet plug formation, platelets are activated and emit pseudopods upon contact with

collagen.

The _______________is/are responsible for the reabsorption of fluid from the tissues back to the blood.

colloid osmotic pressure of the blood.

When iron is removed from it, the heme group is

converted to biliverdin.

47- The most immediate protection against blood loss is

vascular spasm.

The most immediate protection against blood loss is

vascular spasm.

Excess of iron is removed in the liver and spleen and it is stored in two special proteins-iron complex called

ferritin and hemosiderin.

In order to nourish surrounding tissues, substance must pass from the bloodstream to the extracellular fluid. This flow of fluid is produced by the

hydrostatic pressure of the blood (blood pressure).

Which of the following leukocytes is considered an agranulocyte?

lymphocyte

____________ coordinate actions of other immune cells, produce and secrete antibodies, and provide immune memory.

lymphocytes

_______________ are the largest leucocytes.

monocytes

________________ leave bloodstream and transform into macrophages, which phagocytize pathogens and debris and "present" antigens to activate other immune cells.

monocytes

Differential count of ______________ typically increases in response to bacterial infections.

neutrophils

four

After expired erythrocytes break up in liver and spleen, the hemoglobin is degraded in the liver into

heme and globin.
