Arterioles flow into what blood vessel?
Capillaries
Do capillaries have valves to regulate blood flow?
Capillaries do not have valves to regulate blood flow. Veins are the vessel of the circulatory system that have veins to regulate blood flow.
What vessels control the flow of blood through the capillaries?
Arterioles.
What vessel play a key role in regulating blood flow into capillaries?
arterioles
Regulate blood flow to the capillaries?
albumin
In which part of the circulatory system does the greatest pressure drop occur?
The greatest pressure drop in the circulatory system occurs in the arterioles. Arterioles are small, muscular blood vessels that regulate blood flow and control blood pressure. As blood travels from the arteries to the capillaries, the arterioles cause a significant decrease in pressure to ensure proper exchange of nutrients and waste between the blood and tissues.
How the muscles in an artery regulate blood flow?
There are no muscles in arteries. Arterioles have muscles which can close them, but which has no normal flow control. (Used is stress/shock conditions only) Capillaries have a muscle which can stop all flow through it - it responds to oxygen pressure and is the ultimate control of blood flow.

What does aterioles do?
Arterioles transport blood from Arteries to the Capillaries. They also act as the main regulators of blood flow and pressure.
Direction of blood flow in the capillaries?
Blood flows from arteries to veins or from arterioles (small arteries) to venules (small veins) in a capillary bed.
How do organs regulate their own blood flow?
The organs do this by varying the relative resistance of their own arterioles.
How are arterioles capillaries and venules related?
Arterioles are the small arteries that lead into the capillaries, which connect to cells in the body. Venules are the small veins that the capillaries flow back into, leaving the cells.
