How does blood flow from the heart through the blood vessels?
artery- vein- capillary
How is the blood flow through capillary beds locally controlled?
This involves the local control of smooth muscle in microcirculation. The metarterioles function as shunts to bypass capillaries and the rings of smooth muscle at strategic locations . They can contract to increase blood flow through capillaries and vice versa. The pre-capillary sphincters contract and relax in response to local factors only. Its contraction constricts the capillary and decreases blood flow and vice versa.
Why is it difficult for the blood in veins to return to the heart?
The capillarys are in the lungs and blood flows trough them.As far as I know, blood does not flow back through the capillarys so it most likely does not flow back through the capillary beds.

How does arterial blood differ form capillary blood?

How does blood flow from capillary to venule?
By the process of diffusion.
The structures composed of smooth muscle that direct the flow through capillary bed are called?
precapillary sphincters
For what can one use a capillary rheometer?
A capillary rheometer is used so that you can measure the rate of blood flow from your capillaries. Also, you can measure the rate of the blood flow inside of it, which can help you tell whether or not you have a broken one.
What is the difference between arteriole and venule blood flow?
An arteriole transports oxygenated blood from the arteries to the capillary beds and a venule transports de-oxygenated blood from the capillary beds to the veins.
