~They are the largest veins in the systemic circuit.
At the venule end of a capillary bed, osmotic pressure is ______ than blood pressure, resulting in the net flow of fluid into the capillary.
The medical term for a stroke is
cerebrovascular accident (CVA).
The 2 main forces that control movement of fluid through the capillary wall are blood pressure and _________ pressure

If a small cranial arteriole bursts or is blocked by an embolus, this can lead to a(n) ______, which causes brain tissue to die.
The medical term for a heart attack is
myocardial infarction (MI).
True or false: At the arterial end of a capillary bed osmotic pressure is higher than blood pressure resulting in the net flow of fluid out of the capillary into the tissue.
