Erythropoietin is synthesized by the: Red bone marrow Yellow bone marrow Kidneys Erythrocytes

Kidneys Erythropoietin is a hormone produced by the kidneys to signal the red bone marrow to make more red blood cells.

After moving through the pulmonary circuit, oxygenated blood enters the heart in the: Right atrium Right ventricle Left atrium Left ventricle

Left atrium

The initial stimulus for the vasoconstriction of a blood vessel that occurs in hemostasis is: Plasmin Mechanical damage to the vessel Prothrombinase Thromboxane A2

Mechanical damage to the vessel

Agranular leukocytes that are phagocytic are the: Monocytes Neutrophils Lymphocytes Eosinophils

Monocytes Monocytes become macrophages, which are phagocytic cells.

The most abundant of the leukocytes are the: Neutrophils Lymphocytes Basophils Monocytes

Neutrophils

The buffy coat of centrifuged blood consists mainly of: Ruptured red blood cells whose hemoglobin has sunk to the bottom White blood cells and platelets Gamma globulins The ejected nuclei of red blood cells

White blood cells and platelets

The total blood volume in an average adult is about: 8 liters 1 liter 5 liters 3 liters

5 liters

Which of the following indicates a normal differential count in a healthy adult? 50% neutrophils, 30% lymphocytes, 15% monocytes, 4% eosinophils, 1% basophils 65% lymphocytes, 20% neutrophils, 10% monocytes, 4% eosinophils, 1% basophils 65% neutrophils, 25% lymphocytes, 6% monocytes, 3% eosinophils, 1% basophils 65% neutrophils, 25% lymphocytes, 6% eosinophils, 2% monocytes, 2% basophils

65% neutrophils, 25% lymphocytes, 6% monocytes, 3% eosinophils, 1% basophils

The most abundant of the plasma proteins are the: Gamma globulins Albumins Hemoglobins Clotting proteins

Albumins

Pluripotent stem cells produce: Basophils Neutrophils Thrombocytes All are correct

All are correct

When hemoglobin is broken down, what is extracted? Urobilin Biliverdin Bilirubin All are correct

All are correct

The symptoms of hemolytic disease of the newborn occur because: AntiRh antibodies produced by the mother pass the placenta into the bloodstream of the fetus The baby begins making antibodies to its own A or B isoantigens The baby is premature and is unable to produce enough plasma proteins to keep osmotic pressure at the correct levels The baby has a faulty gene that makes its hemoglobin unable to bind oxygen

AntiRh antibodies produced by the mother pass the placenta into the bloodstream of the fetus

Destruction of red bone marrow from a variety of drugs results in: Pernicious anemia Hemolytic anemia Iron deficiency anemia Aplastic anemia

Aplastic anemia If the marrow is destroyed, red blood cells cannot be made.

Production of enzymes such as histaminase that combat the effects of the mediators of inflammation is an important function of: Monocytes Basophils Plasma cells Eosinophils

Basophils

The purpose for giving RhoGAM to women who have just delivered a child or who have had a miscarriage or abortion is to: Trigger the clotting cascade to prevent excessive bleeding Block recognition of any fetal red blood cells by the mother's immune system Stimulate contraction of uterine smooth muscle to expel all uterine contents Block the stimulation of pain receptors

Block recognition of any fetal red blood cells by the mother's immune system

Inflamed tissues attract phagocytes by a phenomenon called: Lysozymes Chemotaxis Emigration Adhesion

Chemotaxis

What is the arterial anastomosis at the base of the brain? Jugular vein Circle of Willis Cranial artery Brachiocephalic artery

Circle of Willis

Red blood cells do not consume any of the oxygen they transport because they: Do not need to generate ant ATP Use carbon dioxide in the electron transport chain instead of oxygen Cannot remove oxygen from heme once it is attached Do not have the cellular machinery for aerobic ATP production

Do not have the cellular machinery for aerobic ATP production

Type O blood is considered the universal: Donor because there are no antiA or antiB antibodies in plasma Donor because there are no A or B isoantigens on RBCs Recipient because there are no A or B isoantigens on RBCs Recipient because there are no antiA or antiB antibodies in plasma

Donor because there are no A or B isoantigens on RBCs

"5 million per cubic millimeter" is a value falling within the normal adult range for the number of: Platelets Leukocytes Neutrophils Erythrocytes

Erythrocytes

Formed elements that are biconcave discs about 78 microns in diameter are: Erythrocytes Band cells Platelets Blast cells that should not be present in circulation

Erythrocytes

Platelets initially stick to the wall of a damaged blood vessel because: Histamine causes vasoconstriction so that platelets can't fit through the opening Prothrombinase alters the electrical charge of the vessel wall Exposed collagen fibers make a rough surface to which the platelets are attracted Fibrin threads act like glue to hold them there

Exposed collagen fibers make a rough surface to which the platelets are attracted

The percentage of total blood volume occupied by RBCs is called the: White blood cell count Platelet count Hematocrit Red blood cell count

Hematocrit

Which two organs have macrophages that phagocytize/recycle worn out red blood cells? Lungs and liver Spleen and kidneys Spleen and liver Liver and kidneys

Spleen and liver

People suffering from disorders that prevent absorption of fat from the intestine may suffer uncontrolled bleeding because: The fat soluble vitamin K cannot be absorbed, so levels of prothrombin and other clotting factors drop Fat droplets in the blood normally help platelets and other formed elements stick together during hemostasis Fatty acids are necessary for the complete synthesis of fibrin Vitamin B12 cannot be absorbed, so there are inadequate formed elements present to produce a clot

The fat soluble vitamin K cannot be absorbed, so levels of prothrombin and other clotting factors drop

Formed elements that are fragments of larger cells called megakaryocytes are: Erythrocytes Neutrophils Lymphocytes Thrombocytes

Thrombocytes

All of the following are important functions of plasma proteins except: Maintenance of osmotic pressure Protection against blood loss Transportation of oxygen Protection against bacteria and viruses

Transportation of oxygen

True

Teres major has similar actions to latissimus dosri. True False

True Teres major is also called "lats little helper," because it has the same actions.
