There is evidence that certain types of exercise and a rise in temperature of the area can increase blood flow in cutaneous circulation.
Yes, it is called shivering. This muscle activity releases heat and causes the blood flow to increase.
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.
Yes! If it is heated instead of chilled, the blood flow will increase and will lead to bruising of the skin. If iced blood flow will slow and most bruising will not occur
Increase
increase in the diameter of blood vessel. it increases the blood flow
vasoconstriction
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.
Expand
Is increase in blood pressure in the capillaries
Some medications increase blood flow, like inotropics. Others, like vasoconstrictors, may decrease blood flow.

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.
