Answer 1

systole = contract
diastole = relaxation

Question 2

during diastole where does the blood move from and to and through what valves

Answer 2

from atrium into ventricles
via tricuspid and mitral valves

Question 3

Answer 3

the closing of the mitral and tricuspid valves

Question 4

what makes the second heart sound of dub

Answer 4

closing of the aortic and pulmonary valves

Question 5

what is aortic stenosis

Answer 5

when the artery narrows and blood cannot flow normally

Question 6

what might happen to the pressures in the compartments of the heart if one has aortic stenosis

Answer 6

ventricular pressure increases higher (then aortic)
aortic pressure decreases

Question 7

what would happen to the pressure if there is aortic regurgitation

Answer 7

aortic pressure drcreases and the dub (s2) sound is quite as aortic value cant quite shut

Question 8

what stage of the cardic cycle happens after the s2 sound

Answer 8

isovolumentric relaxation

Question 9

the pressure in which chamber is highest during isovolumetric contraction

Answer 9

aorta

Question 10

the lub sound is made after which valve opens

Answer 10

TRICK QUESTION its made after the mitral valve closes not open
