Hemodynamics

Question 1

How does sympathetic stimulation affect venous sytem?

Answer 1

Increase volume (more so than arterial side)

Question 2

How does sympathetic stimulation affect arterial system?

Answer 2

Increase pressure (more so than venous side)

Question 3

What is Ohm’s Law?

Answer 3

Flow = change in pressure / resistance

Question 4

What is describe by Reynold’s number?

Answer 4

Pressure at which flow turns from laminar to turbulent

Question 5

What is the Law of Laplace?

Answer 5

Tension = (change in pressure) x (radius)

Question 6

How is the Law of Laplace described qualitatively?

Answer 6

Wall tension increases with increasing pressure and radius
