What is the relationship between the surface area and the volume of a cell as one increases or decreases so does the other?
Remember that as the diameter of a spherical cell increases, the surface area increases as the square of the diameter, and the volume increases as the cube of the diameter, so volume increases much faster than surface area. The same principle applies for other shapes than spherical cells, but the math is more complicated.
As the diameter of the circle increases what happens to the circumference?
The circumference of a circle increases with an increase in the radius as it is directly proportional its radius.
Where does regulation of peripheral resistance occurs most often?
Arterioles
What happens to the area of a circle when the radius is doubled tripled?
The area increases as the square of the radius (or diameter). So if you double the radius you * 4 (quadruple) the area. Treble the radius, you *9 the area.
What happens to the area of a circle if the diameter is doubled?
If you double the diameter of a circle, the area will quadruple (be 4x greater).The area of the circle increases exponentially with the diameter, or more precisely with the radius, which is 1/2 the diameter. A = (pi)r2Doubling the diameter of a circle will quadruple the area (22 =4).This is easily seen in pizzas, where the dough needed for a 16-inch pizza can be used instead to make 4 pizzas with a diameter of 8 inches.---The equation to find the area of a circle is a=(pi)r2. If the diameter is doubled, then the radius is also doubled, because the radius is just half the diameter.The area of a circle once its radius (and therefore diameter) has been doubled can be expressed as follows: a'=(pi)(2r)2, which simplifies to a'=(pi)(4r2).To find the proportion of a' and a, we just divide the second by the first. This gets us[(pi)(4r2)]/[(pi)(r2)]=4
Is the diameter of the lumen larger in arteries or in capillaries?
Arteries have the largest diameter, then arterioles, and last, capillaries.
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.
What controls the diameter of the arterioles and what do changes in diameter affect?
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
Axon diameter increases noticeably at the nodes of ranvier What purpose does this serve?
the axonal diameter increases due to the myelin wraped tightly around the axon.
What decreases blood flow through arterioles?
Vasoconstriction of an arteriole increases resistance and results in decreased flow through that particular arteriole.
If the wire is increased what should happen to the diameter?
If the length of the wire increases its diameter decreases
What is it called when a bone increases in size?
When the bone increases in diameter, it is called appositional growth.
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 happens to the diameter when heating a circular disc?
It increases.

What happens to the radius of a circle when the diameter is increased by 4?
Radius is half of diameter so it increases by 2.
