Worn-out red blood cells are phagocytized in the

The production of red blood cells is closely linked to the carbon dioxide carrying capacity of the blood. If this capacity is low, the red bone marrow makes a hormone called erythroheparin that stimulates increased RBC production.

During hemostasis, the initial vascular spasm in a damaged blood vessel is stimulated by chemicals released from platelets.

Which following blood tests accurately indicates the rate of erythropoiesis?

The iron liberated by the breakdown of old red blood cells is carried by erythropoietin to the liver for storage.

The percentage of whole blood occupied by red blood cells is called the

Thrombocytes are the only formed element in blood NOT synthesized in red bone marrow.

Lymphocytes are the largest leukocytes.

An individual with _____ blood can theoretically donate blood to recipients of all ABO types.

Plasma proteins are synthesized mainly in the spleen.

Which of the following are general functions of blood?

The type of protein that is most plentiful in blood plasma is called

Anemia can result from either low RBC numbers or low hemoglobin concentrations.

Which of the labeled formed elements in the photomicrographs contain cytosolic vesicles containing chemicals that regulate hemostasis?

A blood clot that is moving in the blood stream is called a thrombus.

Clotting that occurs in an unbroken blood vessel is called

Abnormally low levels of white blood cells, which can be caused by exposure to radiation, is called

An abnormal increase in the number of red blood cells in which the hematocrit is above 55% is called

In a bone marrow transplant, donor bone marrow is injected directly into the recipient's veins.

Cyanosis is primarily caused by too many leukocytes in the blood.
