== == Arterioles are very tiny arteries. In some areas of the body there are places where arteries and veins come together in tiny formations to swap oxygenated blood (in the arteries) for unoxygenated blood (in the veins). (As the veins get smaller they become capillaries, then caprioles.) The arteries are responsible for delivering blood with oxygen from the lungs to the rest of the body. Veins carry the "used blood" with no oxygen back to the heart where it passes into the lungs and picks up more oxygen and gets rid of the carbon dioxide that builds up as our bodies use the oxygen. The arterioles and caprioles come together to swap this blood. Well the above might be true but...... Arterioles are small arteries that deliver blood to the Capillaries. While Venules are small veins that are connected to the Capillaries.
What else can I help you with?
Do arterioles have valves?
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
What blood vessel connects arteries to capillaries?
Arterioles.
What are cardiovascular adadptions?
incorporations of father arterioles by daughter arterioles
Does sympathetic stimulation cause vasodilation of which arterioles?
Sympathetic stimulation causes vasoconstriction of most arterioles in the body, except for arterioles in skeletal muscle and the heart where it causes vasodilation.
Do arterioles have valves?
No; arteries (and arterioles) depend on smooth muscle contraction, whereas veins (and venules) have valves.
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.
Which blood vessel offer most resistance to blood flow?
Arterioles generally have the highest resistance because they are so extremely small.
What are the functions of arterioles?
Arterioles are small blood vessels that carry oxygenated blood to the body tissues.
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
Arterioles carry blood to the heart not away from the heart?
Arteries and Arterioles carry oxygenated blood AWAY from the heart TO the body.
