BMS 300 Exam 3 UPDATED ACTUAL
Exam Questions and CORRECT Answers
Located between the atria and ventricles - CORRECT ANSWER - atrioventricular valves
Located between the right ventricle and the lungs - CORRECT ANSWER - pulmonary
valve
Located between the left ventricle and the aorta - CORRECT ANSWER - aortic valve
The pulmonary artery carries - CORRECT ANSWER - deoxygenated blood
The pulmonary vein carries - CORRECT ANSWER - oxygenated blood
T/F: The fluid between the layers of the mesothelium allows the hearts to slide against the body
wall with reduced friction. - CORRECT ANSWER - True
Pericardium attached to the heart - CORRECT ANSWER - visceral pericardium
Volume does not change, pressure increases - CORRECT ANSWER - isovolumetric
contraction
Cells that line the inside of the heart and valves - CORRECT ANSWER - epithelial
Volume does not change, pressure decreases - CORRECT ANSWER - isovolumetric
relaxation
The stroke volume depends on: - CORRECT ANSWER - End diastolic volume
End systolic volume
, At point C of the pressure volume curve (PV curve): - CORRECT ANSWER - -The
ventricular pressure is greater than the aortic/pulmonary pressure
-The aortic valve opens
-The pulmonary valve opens
Long term (months to years) increases in the pressure required to open the pulmonary valve
would be expected to increase the thickness of the myocardium in the: - CORRECT
ANSWER - right ventricle
What is the route of blood flow in a closed system? - CORRECT ANSWER - Artery,
arteriole, capillary, venule, vein
The coronary arteries fill ______________. - CORRECT ANSWER - During diastole
Well trained athletes have sometimes a higher cardiac output than non-athletes. What is the
reason for that? - CORRECT ANSWER - An increased end diastolic volume increases the
stroke volume
If resistance increases, but flow stays constant, what happens to the pressure in a tube? -
CORRECT ANSWER - Pressure increases
Coronary artery disease results from blocking (occluding) the coronary artery. The dangerous
effects of narrowing the coronary artery result because blood flow in this vessel: - CORRECT
ANSWER - -Decreases with the fourth power of the radius of the coronary vessel, r^4
-Decreases as the narrowing increases the resistance to flow
What is the pacemaker of the heart? - CORRECT ANSWER - SA node
T/F: Cardiomyocytes are multinucleated like muscle cells - CORRECT ANSWER - false
