Mean Arterial Pressure & Hypertension Flashcards
1
Q
Normal Systolic/Diastolic
A
120/80 mmHg
2
Q
Systolic Pressure
A
Pressure generated during ventricular contraction
3
Q
Diastolic Pressure
A
Pressure in the arteries during cardiac relaxation
4
Q
Mean Arterial Pressure (MAP)
A
Average pressure during cardiac cycle (rate of flow); Formula only works at rest: MAP= DBP + 0.33(SBP - DBP)
5
Q
Hypertension
A
High blood pressure= 140/90 mmHg
6
Q
Resistance vessels
A
Arterioles and pre/post capillaries; regulate local blood flow by adjusting the diameter of the vessel when smooth muscle cells contract and relax
7
Q
Exchange vessels
A
Capillaries; Thin walls that allow nutrients from the blood to pass into the body tissues, waste products can also travel through
8
Q
Capacitance vessels
A
Veins; Capable of holding and storing 60-70% of the body’s blood volume
