Lec 14 - SV Regulation 2

Question 1

Therefore, increased heart volume causes blank

Answer 1

Increased pressure due to length tension relationship

Question 2

Spike in wiggers pressure diagram is due to blank

Answer 2

Contraction

Question 3

Learn pressure volume loop

Answer 3

Ok

Question 4

Difference between straight lines of pressure volume loop

Answer 4

Stroke volume

Question 5

Difference between tops of pressure volume loop

Answer 5

Afterload pressure (arterial pressure)

Question 6

Preload is the same as

Answer 6

End diastolic volume

Question 7

Just by laying down, blank increases which increases blank

Answer 7

Volume, stroke volume

Question 8

The pressure volume loop relating to preload is called blank law

Answer 8

Starling’s law of the heart

Question 9

Inotropic effect on length tension relationship

Answer 9

Increases slope of systole curve

Question 10

Depressed inotropy would lead to blank stroke volume so the response is an increase in blank by the kidney

Answer 10

Decreased, volume

Question 11

Increased muscle length will lead to an increased blank due to maximum blank of the cardiac muscle

Answer 11

Ventricular pressure, cross bridging

Question 12

increased blood pressure suddenly can lead to fainting due to such a low blank

Answer 12

stroke volume

Question 13

increased HR causes a decrease in all of these

Answer 13

cycle length, filling time, preload, stroke volume

Question 14

two things that increase SV

Answer 14

cytosolic calcium, preload
