The diameter is the length across the middle of a circle. Half of the diameter is called the radius.

The Radius of a circle is half the Diameter of the circle.
Diameter
Yes, the blood does pulsate in arterioles, but the pulsation is less pronounced than in larger arteries. As blood moves from the arteries into the arterioles, the pressure and pulse wave diminish due to increased resistance and the smaller diameter of the vessels. Arterioles primarily regulate blood flow and pressure to capillaries rather than exhibit strong pulsatile flow.
Arteries have the largest diameter, then arterioles, and last, capillaries.
Arteries branch into smaller vessels called arterioles. Arterioles are small diameter blood vessels that connect arteries to capillaries. They play a crucial role in regulating blood flow and blood pressure within the circulatory system.
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.
Arterioles are the smallest vessels of the arterial system, with a diameter of about 1/3 millimeter or smaller. There is much smooth muscle in their tunica media, which causes vasocontrictionwhen it contracts, and vasodilation when it relaxes. Such vasoconstriction and vasodilation plays two important roles in the cardiovascular system.controls of distribution of blood flow to different parts of the bodydetermines the total peripheral resistance
Arterioles are small diameter vessels that branch off of your arteries. They inevitably connect arteries to capillaries. You can find them pretty much anywhere in your body

It is basically a blood vessel (vein) except it is much smaller in diameter.
the small arteries are called arterioles
the diameter increases as the height is increased
During exercise, the diameter of arterioles dilates primarily due to the release of vasodilators, such as nitric oxide, in response to increased metabolic activity in the muscles. This dilation enhances blood flow to the working muscles, allowing for greater oxygen and nutrient delivery while facilitating the removal of metabolic waste products. Additionally, the sympathetic nervous system's response during exercise helps modulate blood flow, ensuring that active tissues receive adequate perfusion.
