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.
When steadily flowing water flows from a larger diameter pipe to a smaller diameter pipe what happens to its pressure?
When steadily flowing water transitions from a larger diameter pipe to a smaller diameter pipe, its velocity increases due to the principle of continuity, which states that the flow rate must remain constant. According to Bernoulli's principle, as the velocity of the fluid increases, its pressure decreases. Therefore, the pressure in the smaller diameter pipe is lower than in the larger one.
Where does regulation of peripheral resistance occurs most often?
Arterioles
How the current depend on diameter?
The current flowing through a conductor is influenced by its diameter due to its effect on resistance. A larger diameter reduces resistance, allowing more electrons to flow, resulting in a higher current for a given voltage. According to Ohm's Law (I = V/R), as resistance decreases with increasing diameter, the current (I) increases when voltage (V) is constant. Therefore, wider conductors can carry greater currents more efficiently.
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
What Site has the greatest resistance to blood flow?
The site with the greatest resistance to blood flow is the arterioles, which are small branches of arteries. Arterioles have a high resistance due to their small diameter and ability to regulate blood flow to tissues. This resistance plays a key role in maintaining blood pressure and distributing blood throughout the body.
What decreases blood flow through arterioles?
Vasoconstriction of an arteriole increases resistance and results in decreased flow through that particular arteriole.
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.
Arteries branch into smaller vessels called?
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.
What is it called when a bone increases in size?
When the bone increases in diameter, it is called appositional growth.
Know relationships and differences between Afferent vs efferent arterioles?
afferent glomerular arteriole a branch of an interlobular artery that goes to a renal glomerulus.efferent glomerular arteriole one arising from a renal glomerulus, breaking up into capillaries to supply renal tubules.Remember because they are arterioles NOT venules they they both carry blood away from the heart.
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.
