BMS 300 Exam 3 material UPDATED
Exam Questions and CORRECT Answers
The fluid between the layers of the mesothelium allows the hearts to slide against the body wall
with reduced friction. - CORRECT ANSWER - true
volume does not change, pressure decreases - CORRECT ANSWER - isovolumetric
relaxation
volume does not change, pressure increases - CORRECT ANSWER - isovolumetric
contraction
cells that line the inside of the heart and valves - CORRECT ANSWER - endothelial
pericardium attached to the heart - CORRECT ANSWER - visceral pericardium
at point C on the Pv graph, what occurs: - CORRECT ANSWER - The ventricular pressure
is greater than the aortic/pulmonary pressure
The aortic valve opens
Z-lines _______________ during ventricular contraction (systole). - CORRECT
ANSWER - 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: - 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
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? -
CORRECT ANSWER - pressure increases delta P=flow x resistance
pressure and resistance are proportional when flow is constant
The stroke volume depends on: - CORRECT ANSWER - Edv and Esv
An increase in end diastolic volume (EDV): - CORRECT ANSWER - 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: - CORRECT ANSWER - plasma
The site in lymph nodes where B lymphocytes reside is the - CORRECT ANSWER -
germinal center
Which of the following is not a sign of inflammation? - CORRECT ANSWER - bleeding
During inflammation, the granulocyte that releases its contents of bleach and hydrogen peroxide
is the: - CORRECT ANSWER - neutrophils
Which of the following cell types does not participate in antigen presentation to T helper cells? -
CORRECT ANSWER - t killer cells
What is the primary pacemaker of the heart? - CORRECT ANSWER - SA node
sinoatrial node is the primary pacemaker
