Systemic pressure is mainly affected by:

Diastolic pressure is mainly affected by:

Arterial BP is under short and long-term control

Eg. of baroreceptor control

Drugs and BP:

1) Increase TPR by vasoconstricting

Drugs and BP:

2) Increase CO by increasing HR or SV

Drugs and BP:

3) Decrease TPR by vasodilating
