Blood flow can be increased in two main ways: firstly, the heart can pump blood round the body at a faster rate i.e. by increasing blood flow. Secondly, vasodilation can take place, by which blood vessels "expand" in order to allow more blood to pass through. This process is mainly used during exercise, when our body needs to lose excess heat energy.

How can blood flow through the cutaneous circulation be increased?
There is evidence that certain types of exercise and a rise in temperature of the area can increase blood flow in cutaneous circulation.
Does the circulatory system speed up blood flow to heat you up?
Yes, it is called shivering. This muscle activity releases heat and causes the blood flow to increase.
How is high blood hydrostatic produced?
High blood hydrostatic pressure in blood vessels is produced when there is an increase in blood flow and these vessels become hard. This can lead to hypertensive conditions and even edema.
Does exercise increase or decrease the flow of the blood in muscle capillaries?
Increase
What is Vasolidation?

What increase blood flow through arterioles?
vasoconstriction
How can the vascular system increase blood flow to specific area of the body?
Except in cases of massive blood loss, it's not the job of the vessels to increase or decrease blood flow, but of the capillary beds.

No
What neurotransmitters is released by active neurons to dilate the blood vessels and increase blood flow?
acetylcholine
What is tissue perfusion?
Blood flow and tissue perfusion are NOT the same thing. An increase in blood flow does not always mean that there is a parallel increase in tissue perfusion. While blood flow is generally understood as an increase in the total amount of blood flowing into an anatomic structure or region, tissue perfusion is the amount of blood that actually flow through the capillaries of the vascular bed of that structure or region. The important thing to remember is that nutrients and oxygen are delivered to the cells via the capillaries.
What would lead to increase erythropoiesis?
