BLG 111 Final Exam Review Questions
with Quality Answers 2026 Updated.
What are granulocytes? Name one exception. - Answer Granulocytes are a type of white
blood cell that includes eosinophils, neutrophils, and basophils. An exception is monocytes.
Which cells release histamine and what is its function? - Answer Basophils release histamine,
which acts as a vasodilator and attracts white blood cells to inflamed sites.
What functions do plasma proteins and platelets serve in blood? - Answer They prevent
infection as agents of immunity and prevent blood loss by initiating clot formation.
What is NOT correct about erythrocytes? - Answer Erythrocytes are filled with hemoglobin
for oxygen transport, but they do not have organelles.
What is true about hemoglobin? - Answer Hemoglobin binds reversibly with oxygen, has 4
chains (2 alpha & 2 beta), and 1 heme per chain.
Where is erythropoietin produced in the body? - Answer Erythropoietin is produced in the
kidneys.
What is the third event of homeostasis? - Answer The third event of homeostasis is
coagulation.
What protein stores iron in the body? - Answer Ferritin is the protein that stores iron and
releases it when needed.
What is the difference between a thrombus and an embolus? - Answer A thrombus is a clot
that develops in an unbroken blood vessel, while an embolus is a piece of this clot that floats
freely in the bloodstream.
What is a cause of anemia? - Answer Anemia is not caused by producing too many red blood
cells (RBCs).
What plasma antibodies are found in Blood Group AB? - Answer Blood Group AB has no
plasma antibodies, so the answer is 'None'.
What is the role of the left side of the heart? - Answer The left side of the heart receives
oxygenated blood from the lungs and pumps it to body tissues via the systemic circuit.
, What do contractile cardiac myocytes NOT do? - Answer Contractile cardiac myocytes do not
depolarize spontaneously; they maintain a stable resting potential until activated.
What is NOT true about the Sympathetic nervous system? - Answer It is NOT connected to
the cardioinhibitory center in the brain stem and does not decrease heart rate.
From which structure does blood flow from the right ventricle? - Answer Blood flows from
the right ventricle into the pulmonary arteries.
How is oxygenated blood carried to the heart? - Answer Oxygenated blood is carried to the
heart by the pulmonary veins.
What type of blood does the pulmonary trunk carry? - Answer The pulmonary trunk carries
deoxygenated blood from the right ventricle to the lungs.
What is true about the Tricuspid Valve? - Answer The Tricuspid Valve prevents deoxygenated
blood from flowing back into the right atrium from the right ventricle.
What prevents backflow from major arteries into the ventricles? - Answer The pulmonary
semilunar valve is located between the right ventricle and pulmonary trunk and prevents
backflow.
What is the location of the aortic semilunar valve? - Answer Between the left ventricle and
the aorta.
What is the location of the pulmonary semilunar valve? - Answer Between the right ventricle
and the pulmonary trunk.
What happens when pressure is high in the ventricles? - Answer The semilunar valves close
as the ventricles contract, ejecting blood.
When do the semilunar valves close? - Answer When the ventricles relax and fill with blood,
causing low pressure in the ventricles.
What is the anatomical location of the heart? - Answer Between the second rib and fifth
intercostal space, on the superior surface of the diaphragm, posterior to the vertebral column,
and anterior to the sternum.
