BMS 300 Exam 3 [2026/2027] | UPDATED
ACTUAL Exam Question and Answer |
Frequently Tested Questions
• volume does not change, pressure decreases -✓✓ isovolumetric relaxation
• volume does not change, pressure increases -✓✓ isovolumetric contraction
• cells that line the inside of the heart and valves -✓✓ endothelial
• pericardium attached to the heart -✓✓ visceral pericardium
• at point C on the Pv graph, what occurs: -✓✓ The ventricular pressure is greater
than the aortic/pulmonary pressure
The aortic valve opens
• Z-lines _______________ during ventricular contraction (systole). -✓✓ shorten
• 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: -✓✓ right ventricle
• What is the route of blood flow in a closed system? -✓✓ Artery, arteriole,
capillary, venule, vein
• The coronary arteries fill ______________. -✓✓ during diastole
, contraction of the heart squeezes the coronary arteries closed during systole
• If resistance increases, but flow stays constant, what happens to the pressure in a
tube? -✓✓ pressure increases delta P=flow x resistance
pressure and resistance are proportional when flow is constant
• The stroke volume depends on: -✓✓ Edv and Esv
• An increase in end diastolic volume (EDV): -✓✓ an increase in stroke volume
an increase in ventricular contraction
this will increase length of sarcomeres and allow for greater contraction of the
ventricle
• A little more than half of whole blood is composed of: -✓✓ plasma
• The site in lymph nodes where B lymphocytes reside is the -✓✓ germinal center
• Which of the following is not a sign of inflammation? -✓✓ bleeding
• During inflammation, the granulocyte that releases its contents of bleach and
hydrogen peroxide is the: -✓✓ neutrophils
• Which of the following cell types does not participate in antigen presentation to T
helper cells? -✓✓ t killer cells
• What is the primary pacemaker of the heart? -✓✓ SA node
