When the hormone erythropoietin is released in response to low oxygen levels, where is it transported to stimulate red blood cell production?

• kidney

• spleen

• liver

• red bone marrow

When a person who lives at sea level vacations in the Rocky Mountains, you would expect   

• the release of erythropoietin. 

• an increase in red blood cell production. 

• a drop in oxygen levels.

• All of the answers are correct.

Which one of the following is not a type of leukocyte?

• monocyte

• neutrophil

• basophil

• erythrocyte

The process of red blood cell production is called

• erythropenia

• hemocytosis

• erythropoiesis

• hematopenia

Bilirubin is used to make _____________                    

                

• hemoglobin

• erythropoietin         

• bile

• WBCs 

A damaged red blood cell is removed from circulation by

• basophils releasing histamine to stimulate breakdown of RBCs.

• phagocytosis by macrophages in the spleen.

• endocytosis directed by monocytes.

• being actively transported into macrophages in the liver and spleen.

Which of the following is not a phase of hemostasis?

• platelet plug formation

• breakdown of fibrin

• coagulation (proteins binding to platelets)

Consider these results from a blood lab test. Which value is most likely abnormal?

• RBCs–2.2 million/µl

• leukocytes–8600/µl

• platelets - 350,000/ul

An obstruction in blood flow to the kidneys would ultimately result in

• decreased erythropoiesis

• increased erythropoiesis
