Does blood flow more rapidly in the capillaries or in arteries?

Remember arteries come from the heart, and veins go from the organs back to the heart. Therefore, as the heart is the main pump, the arteries have the greatest pressure, so "the blood flow is more rapid in arteries."

∙ 13y agoHemoglobin is equal in arteries and veins!!
Hemoglobin is just a carrier molecule for transport of oxygen to tissues.
In the arteries, there is oxygenated hemoglobin, which reaches the tissues via capillaries, releases the oxygen molecule to the tissues and gets converted to reduced hemoglobin (deoxyhemoglobin).
We can surely say that, oxyhemoglobin is more in arteries while deoxyhemoglobin is more in veins, but the total quantity or concentration of hemoglobin, per say, remains the same in arteries and veins

Is it true that the pulse can be felt on arteries but not on veins?
Yes, it's true. The beating of the heart only drives blood in the arteries. As the blood passes from the arteries to the capillaries and then to the veins, it ceases to be pumped by the heart, so no pulse can be felt. Blood in the veins returns to the heart because of the valves in the veins, and because of general muscular contractions in the body, rather than because of the heart.
How do 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.
A measure of the flow of the blood in arteries is called?
blood pressure
Where does blood flow after the arteries?
From the arteries, the blood flows into the capillaries where food and oxygen diffuse through the one-cell-thick capillary walls and into the cells. Carbon dioxide and cellular wastes then diffuse into the blood. The capillaries then form veins. The veins then lead back to the heart so the blood can be sent to the lungs to be oxygenated. The blood is then pumped through the arteries to the rest of the body again.
True or False Arteries have valves to allow blood to flow away from the heart?
true. Arteries have halves that allow for blood flow away form the heard but not toward the heart.
Which blood vessels allow blood to flow between the arteries and veins?
Capillaries.
What vessel play a key role in regulating blood flow into capillaries?
arterioles
Blood flow in the body follows the pattern of?
Heart to arteries to capillaries to veins.
When is the speed of blood slowest in blood vessels?
Veins are where the blood flow is the slowest. Blood flow velocity decreases from the aorta to the arteries to capillaries.
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.
From Where does blood flow to the capillaries and where the blood flows further into?
the oxygenated blood flows from arteries to capillaries and after the exchange of material in capillaries and tissues it goes to vein and veins carries this deoxygenated blood to heart.
Does blood move more rapidly or less rapidly after it flows from the capillaries into a vein?
more rapidly, in the capillaries the blood cells flow in "single file". In the veins, multiple cells are allowed to pass at once
What does aterioles do?
Arterioles transport blood from Arteries to the Capillaries. They also act as the main regulators of blood flow and pressure.
What are the tubes that flow through the in the body?
Tubes that carry blood are collectively known as blood vessels. These include veins, arteries, and capillaries.
Blood flow through the capillaries is steady despite the rhythmic pumping action of the heart because of?
Elasticity of the large arteries.
How do you define closed circulatory system?
When the blood flow pumped by the heart is confined in the vessels( veins,arteries, capillaries.)
What do arteries flow into before flowing into venules?
capillaries
