No; arteries (and arterioles) depend on smooth muscle contraction, whereas veins (and venules) have valves.

What comes first the arterioles or the aorta?
aorta
Are arteries the main artery in your body?
There are five types of bloods vessels: arteries, arterioles, capillaries, venules, and. Arteries distribute blood to the body and arterioles, the arterioles mostly innervate tissues and organs. Systemic arteries and arterioles hold about 13% of the bodies blood at any given time. The aorta is the largest artery in the body, it starts at the heart and ends just above the pelvis.
How is the structure of arterioles different from that of arteries?
The wall of the arterioles contain less elastic fibers but more smooth muscle cells than that of the aorta and arteries.
How do arterioles in the dermis respond to a cold environment?
Constrict
The arteries that directly feed into the capillary beds are called?
arterioles
Which sphincters function as regulatory valves that reduce the flow of blood through a network of capillaries when they contract and constrict the arterioles?
Precapillary sphincters
Do arterioles contain non return valves?
you find non return valves inside the heart, lymph and veines, avoiding fluids from flowing backwards > [veinous blood in veines and heart, oxygenated blood in the heart]. Lymph vessels have valves also. The portal vein though contains no valves. All arteries including arteriols and capillaries have no valves.
What are cardiovascular adadptions?
incorporations of father arterioles by daughter arterioles
What blood vessel connects arteries to capillaries?
Arterioles.
What happens to arterioles when the body temperature falls?
I have same question It happens a dilation of the arterioles.
Structure and function of arterioles?
The function of arterioles is to draw blood away from the brain and into harry bush's penis.
What vessel play a key role in regulating blood flow into capillaries?
arterioles
Where does a capillary arise from?
Arterioles
Do muscular arteries branch into arterioles?
Yes blood passes through Elastic Arteries, Muscular Arteries, and then Arterioles.
Contraction of the smooth muscle in arterioles would decrease blood pressure?
No it would increase BP, as contraction of the smooth muscle in the arterioles will make the lumen (holes) of the arterioles smaller, restricting blood flow.
What are examples of arterioles?
There isnt exactly specific arterioles because every conduction system of Arteries flow from Elastic arteries -> muscular arteries -> arterioles. Arterioles are the smallest of the arteries and produce the greatest vascular resistance of blood. The blood then passes onto capillaries for gas/waste/nutrient exchange.
Which blood vessel offer most resistance to blood flow?
Arterioles generally have the highest resistance because they are so extremely small.
