A. They distribute blood to various parts of the body.
B. They contain a large quantity of elastic tissue.
C. The contraction and relaxation of the smooth muscle in their walls can change their diameter.
D. Their prime function is the exchange of nutrients and wastes between the blood and tissue cells.
What else can I help you with?
What Site has the greatest resistance to blood flow?
The site with the greatest resistance to blood flow is the arterioles, which are small branches of arteries. Arterioles have a high resistance due to their small diameter and ability to regulate blood flow to tissues. This resistance plays a key role in maintaining blood pressure and distributing blood throughout the body.
How did you distinguish between arterioles and venules when you observed the vessels in the frog's foot?
Arterioles are smaller vessels that carry blood away from the heart, while venules are smaller vessels that carry blood back to the heart. By observing the direction of blood flow and the presence of valves (which venules have), one can distinguish between arterioles and venules in the frog's foot vasculature.
Contraction of the smooth muscle in arterioles would decrease blood pressure?
Contraction of smooth muscle in arterioles would lead to vasoconstriction, which would increase resistance to blood flow and subsequently increase blood pressure. Conversely, relaxation of smooth muscle in arterioles (vasodilation) would decrease resistance and lower blood pressure.
How do you distinguish between arterioles and venules?
Arterioles are small blood vessels that carry oxygenated blood away from the heart to the capillaries, while venules are small blood vessels that collect deoxygenated blood from the capillaries and carry it back to the heart. Arterioles typically have thicker walls and are more muscular than venules to help regulate blood flow and pressure, while venules have thinner walls and lower pressure.
Which Site is the major determinant of peripheral resistance?
Arterioles are the major determinant of peripheral resistance in the cardiovascular system. Their small diameter and ability to constrict or dilate play a key role in regulating blood flow and pressure in different parts of the body.
Which blood vessel offer most resistance to blood flow?
Arterioles generally have the highest resistance because they are so extremely small.
What is main site of peripheral resistance?
arterioles offer maximum peripheral resistance .Skin and skeletal muscle blood vessels represent most imp. site of peripheral resistance.
What are arterioles and what are capillaries?
Arteioles are blood vessels that connect arteries and capillaries. Capillaries are blood vessels that connect arterioles and venules
What connects blood vessels to arteries?
Arterioles.
Site where resistance to blood flow is the greatest?
The resistance to blood flow is greatest in arterioles, which are small blood vessels that regulate blood flow to tissues and organs. Arterioles have a high resistance due to their small diameter and ability to constrict or dilate to control blood flow distribution. This resistance plays a key role in regulating blood pressure and blood flow to different parts of the body.
When there is increased resistance then arteriolar constriction and pressure drops?
Resistance changes dramatically with changes in diameter of blood vessels (arterioles are one type of blood vessel). If you INCREASE the diameter of the arteriole, you DECREASE the resistance and thus DECREASE the blood pressure.
In blood vessels where does the greatest pressure drop occur?
the arterioles
What vessels control the flow of blood through the capillaries?
Arterioles.
What blood vessels carry blood toward the capillaries?
arterioles
What are the functions of arterioles?
Arterioles are small blood vessels that carry oxygenated blood to the body tissues.
What vessels have smooth muscle in their walls?
Those would be they Arteries and arterioles.
What Site has the greatest resistance to blood flow?
The site with the greatest resistance to blood flow is the arterioles, which are small branches of arteries. Arterioles have a high resistance due to their small diameter and ability to regulate blood flow to tissues. This resistance plays a key role in maintaining blood pressure and distributing blood throughout the body.
