What else can I help you with?
What would not result in the dilation of the feeder arterioles and opening of the precapillary sphincters in systemic capillary beds?
a local increase in pH
Why does arteriole dilation increase capillary pressure and flow but venous dilation does not?
Blood flow in the circulatory system is as follows: arteries->arterioles->capillaries->venules->veins. if you dilate the arteriole you are in fact lowering the resistance of the vessel (Poiseuille's Law), and it follows that net flux will increase. If capillary resistance remains the same, but the net flux has increased, then there will be an upwards change in pressure (Ohm's law). As far as veins go, it has a high compliance, which means that it can store large amounts of blood without raising venal pressure. If your question asked whether or not capillary pressure increases when venous dilates then the answer is no. Capillary blood flow will be less restricted as they flow into venules->vein and therefore will not have an increased pressure. If the question asked whether or not the venal pressure increases, then the answer is yes, but it is negligible (it has high compliance).

What is the procedure for dilation of the kidney?
The procedure for dilation of the kidney?
What is the most common external type of bleeding?

What is the opposite of dilation in math?
The opposite of dilation in math is contraction
Which is thicker an artery or a capillary?
a capillary
How do you dilate by .50 with (66)?
Dilation (or enlargements require a centre of dilation (or enlargement). Since none has been given, no dilation is possible.
What is ateriole dilation?
Arteriole dilation is an increase in the diameter of a small artery.
What is capillary reabsorption?
fluid entering the capillary
When the osmotic pressure in a capillary exceeds the blood pressure in the capillary what is the net movement of fluid?
water and waste will move in capillary . water and waste will move in capillary .
