Answer: Calcitriol increases blood levels of calcium by increasing the absorption of calcium in the kidneys, increasing the absorption of calcium and phosphorus from the intestine, and increasing the release of calcium and phosphorus from the bones. Calcitriol helps the body to use calcium found in foods and supplements.

In regions of the cardiovascular system where there is steady laminar blood flow, the shear stress on cells lining the walls of

Lynna [10]

Answer:

$250$ N/m2

Explanation:

Shear stress on cells lining the walls of the blood vessels is equal to $20$ 20 dyne/cm2

In terms of Newton/square meter, shear stress is equal to

$20*\frac{dyne}{cm^2} (\frac{10^{-5}N}{1 dyne} )*(\frac{1 cm^2}{10^{-4}*m^2} )\\= 2.0$ N/m2

Shear modulus is equal to shear stress divided by shear strain

Thus, shear modulus is equal to

$= \frac{2.0}{0.008} \\= 250$ N/m2
