If plaque buildup reduces the radius of the artery by a factor of 2, the flow rate becomes 1/16th of the original.
Coronary heart disease results from a deposition of plaque in the blood vessels which transport blood to the heart. When the flow of blood to the heart is hampered or obstructed, the heart can be harmed due to a deficiency of oxygen.
Moreover, if a large section of plaque that is deposited gets displaced from an artery wall, it can get stick in other arteries in the body as well, including those present in the brain.
For convenience, an assumption can be made that the artery is cylindrical in shape with a radius of R. The flow rate of a viscous fluid (blood in this case) is determined by Poiseuille's Law, i.e. Q = (π/8) (ΔP/ηl)r4.

The recommended guideline for determining suction catheter depth when suctioning an endotracheal tube is;
<u><em>By using a suction catheter with centimeter increments on it.</em></u>
<u><em>Insert the suction catheter into the endotracheal tube until the centimeter markings on both the endotracheal tube and catheter align</em></u>
<u><em>Insert the suction catheter no further than an additional 1 cm.</em></u>
<u><em /></u>
From documented guidelines to determine suction catheter depth, they are;
1) Get a suction catheter with centimeter increments on it.
2) Then you will Insert the suction catheter into the endotracheal tube till the centimeter markings located on both the endotracheal tube and catheter align
3) Next is to insert the suction catheter not more than an extra 1 cm.
4) The length of the endotracheal tube should be combined with any other adapter you are using after which you add an additional 1 cm.
5) Get a spare <em>endotracheal tube</em> that has same size as that being used for the patient.
6) Insert the suction catheter to the end of this tube and take note of the length at which the catheter got to the end of the tube.
7) If you are dealing with a closed system, then all you need to do is to combine the endotracheal tube length and length of additional adapters you are using and add an extra 1 cm.

<span>A) the alleles that are on the most chromosomes</span>
Answer:
Lithosphere is made up of Earth's outermost layer, the crust, and the uppermost portion of the mantle. In comparison, the asthenosphere is the upper portion of Earth's mantle (which is also the middle layer of Earth). ... Both the lithosphere and asthenosphere are part of Earth and are made of similar material.
Answer: “me’s” genotype is Dd and he has dimples.
Claim me has dimples
Evidence of me has the allele D from father then me has to get the d allele from mother
Reasoning Dd means he has dimples
Phenotype is that he has dimples
Hope this helps
