Under normal conditions, a person’s blood should be approximately 45% cells and 55% plasma. When blood is “spun down” in a centrifuge to easily view and record the percentage of blood cells, this number is called the
hematocrit
The most abundant blood plasma protein, and thus the greatest contributor to blood pressure and volume, is
albumin
Which of the following is NOT a direct function of the blood?
converting light signals into chemical signals
The general category of chemicals that stimulate hemopoiesis are called
colony-stimulating factors (CSFs)

astrocytes
Lymphoid stem cells give rise to lymphocytes, which includes all of the following, EXCEPT

hematopoiesis; bone marrow
Which of the following is NOT a possible cause of anemia?
hypoxia
The molecule in red blood cells that actually carries the oxygen is
hemoglobin
Erythrocyte production is stimulated by
erythropoietin
turn into macrophages
monocytes
inflammatory reactions
basophils
attack parasites
eosinophils
eat bacteria
neutrophils
fight viruses and cancer
lymphocytes
Cancer of T cell or B cell lines in lymphatic organs, such as the lymph nodes, is known as
lymphoma
A patient has cancer of the myeloid leukocyte line. They are overproducing non-functional cells. Which type of leukemia does this patient have?
AML
A common anticoagulant used in hospital settings with immobilized patients is
heparin
Platelets are not technically cells; they are actually
fragments of megakaryocytes
Clots that are no longer needed are dissolved by
plasmin
There is a family of disorders in which patients cannot properly clot their blood called
hemophilia
Platelets can do all of the following EXCEPT
carry oxygen to increase the rate of hemostasis
When a clot moves to another place in the body, the name is changed to a(n)
embolus
Blood coagulation occurs when thrombin converts fibrinogen into
fibrin
