Control of Blood Pressure Flashcards
1
Q
What drives blood flow to tissues?
A
Driven by the difference in pressure between the arterial and venous sides of circulation.
2
Q
What is MEAN ARTERIAL PRESSURE?
A
The driving force for blood flow, and it must be maintained at a high constant level of 100mmHg
3
Q
What are the physiological systems that regulate arterial pressure?
A
- Rapidly responding systems
- Less rapidly responding systems
- Slowly responding systems
4
Q
What are rapidly responding systems?
A
- Baroreceptors
- Chemoreceptors
- Regulation of Stroke volume by areterial pressure
- Cerebral Ischemia induced response
5

A
- Stroke volume
2. Heart Rate
6
