If the antenna diameter in radar system is increased by a factor of 4 then the maximum range will be increased by a factor of?
16
What is diameter of?
The diameter is the length across the middle of a circle. Half of the diameter is called the radius.
Is EMT called by it inside diameter or outside diameter?
inside
What is radius of the diameter called?
The Radius of a circle is half the Diameter of the circle.
What is it called when a radius doubles?
Diameter
Is the diameter of the lumen larger in arteries or in capillaries?
Arteries have the largest diameter, then arterioles, and last, capillaries.
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.
What controls the diameter of the arterioles and what do changes in diameter affect?
The diameter of arterioles is primarily controlled by changes in smooth muscle tone in their walls. Constriction of arterioles leads to increased vascular resistance and higher blood pressure, while dilation results in decreased resistance and lower blood pressure. Changes in arteriolar diameter can affect local blood flow, regulate blood pressure, and influence organ perfusion.
When a muscle increases in diameter this increased growth and development is called?
Hypertrophy
Where are arterioles located?
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
What are arterioles in the skin and digits?
It is basically a blood vessel (vein) except it is much smaller in diameter.
The smallest arteries are called?
arterioles
What is the artery called?
the small arteries are called arterioles
What did you notice about the diameter of the parent droplets as you increased the height of the drop?
the diameter increases as the height is increased
What causes arterioles to dilate in response to increased sympathetic tone?
Increased sympathetic tone leads to the release of norepinephrine, which binds to alpha-1 adrenergic receptors on arteriolar smooth muscle. This binding initiates a signaling cascade that ultimately results in the relaxation of the smooth muscle, causing the arterioles to dilate.
The arteries that directly feed into the capillary beds are called?
arterioles
Which blood vessel offer most resistance to blood flow?
Arterioles generally have the highest resistance because they are so extremely small.
