1. describe the effect that the increasing the calcium ions had on the heart?
2. describe the effect that incresing the potassium ions initally had on the heart. relate this to resting membrane potential of the cardiac muscle cell?
3.describe how calcium channel blockers are used to trest patients and why?

3. describe thr graph flow versus viscosity?
4. discuss the effect that polycythemia would have on viscosity and blood flow?

1. explain how the heart could compensate for changes in peripheral resistance?
2. which mechanism had the greatest compensatory effect?
3. explain what happened when the pump pressure and breaker pressure were the same?
4. explin whether it woud be better to adjust heart rate or blood vessel diameter to achieve blood flow changes at local level?

3. describe thr graph flow versus viscosity?

The graph was not linear. It was exponential. It showed also that the relationship between viscosity and flow is inversely proportional.

1. explain how the heart could compensate for changes in peripheral resistance?

The heart can compensate for changes in peripheral resistance by increasing contractility.

Good luck!
