BMS 300 EXAM 3 MATERIAL QUESTIONS AND
ANSWERS
The fluid between the layers of the mesothelium allows the hearts to slide
against the body wall with reduced friction. - ANSWER true
volume does not change, pressure decreases - ANSWER isovolumetric
relaxation
volume does not change, pressure increases - ANSWER isovolumetric
contraction
cells that line the inside of the heart and valves - ANSWER endothelial
pericardium attached to the heart - ANSWER visceral pericardium
at point C on the Pv graph, what happens: - ANSWER The ventricular
pressure is higher than the aortic/pulmonary pressure
The aortic valve opens
Z-lines _______________ during ventricular contraction (systole). - 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: - ANSWER right ventricle
, What is the route of blood flow in a closed system? - ANSWER Artery,
arteriole, capillary, venule, vein
The coronary arteries fill ______________. - ANSWER during diastole
contraction of the heart squeezes the coronary arteries closed during systole
If resistance goes up, but flow remains the same, what happens to the pressure
in a tube? - ANSWER pressure goes up delta P=flow x resistance
pressure and resistance are proportional when flow is constant
Stroke volume is dependant on: - ANSWER Edv and Esv
An increase in end diastolic volume (EDV): - 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: - ANSWER plasma
The site in lymph nodes where B lymphocytes reside is the - ANSWER
germinal center
Which of the following is not a symptom of inflammation? - ANSWER
bleeding
