Local Blood Pressure Control

Question 0

How does hyperemia correspond with duration of occlusion

Answer 0

The peak flow increases rapidly then plateaus, the duration of excess blood flow increases as duration of occlusion increases

Question 1

Hyperemia

Answer 1

Increase in blood flow, usually referring to a certain metabolically active organ

Question 2

In cases of ischemia, how does micro vascular injury occur

Answer 2

During reperfusion, the sudden increase in oxygen leads to reactive oxygen species and inactivates NO

Question 3

The two ways adenosine vasodilates

Answer 3

Through hyperpolarization of vas sm muscle cAMP cascade

Through preventing phosphorylation of myosin and decreasing contractility
