pressure changes in heart chambers

Question 1

how does the pressure change in atrial systole

Answer 1

-aortic pressure remains the same
-ventricle pressure rises as blood enters ventricle
-atrial pressure rises as blood enters atria

Question 2

how does the pressure change in the ventricular systole affect aortic pressure

Answer 2

-aortic pressure increases as semi-lunar valves open so intake of blood from ventricle

Question 3

how does the pressure change in the ventricular systole affect ventricular pressure

Answer 3

-atrioventricular valve closes so blood cant go back, rapid increase in pressure
-pressure slopes off as blood leaves ventricle

Question 4

how does the pressure change in the ventricular systole affect arterial pressure

Answer 4

-initial decrease as blood leaves atria
-slight increase as blood enters atria

Question 5

how does pressure change in the diastole affect aortic pressure

Answer 5

-initial bump/ increase as pooling of blood due to semi-lunar valve shutting and blood getting sucked back
-then decrease in pressure

Question 6

how does pressure change in the diastole affect ventricular pressure

Answer 6

-rapid decrease in pressure causing pressure to be lower than atria
-causes a slight increase as blood is drawn in

Question 7

how does pressure change in the diastole affect atrial pressure

Answer 7

-chamber gets bigger so initial decrease
-slight increase as blood coming in
