The answer is: d. atherosclerosis, hypertension and high blood cholesterol
Atherosclerosis refers to a condition that caused by the build up of plaque within your artery wall and this would increase the speed of blood flow that lead to hypertension that caused heart attack and stroke. This condition could also be caused by high blood cholesterol that build up a blockage in your artery.
Answer:
Lumen corresponds to the central opening of a vessel (option d).
Explanation:
From the biological point of view, lumen is the internal space of any structure or tubular organ, whose purpose is the conduction of substances through it.
In the case of blood vessels, the lumen is a central space covered by a simple epithelium, called the endothelium, which ensures the passage of blood in a fluid form.
The other options do not correspond to the answer:
<em> a. </em><u><em>Vessel that empties into the right atrium</em></u><em> is the vena cava</em>
<em> b. </em><u><em>Fibrous sac around the heart </em></u><em>is the pericardium.
</em>
<em> c. </em><u><em>Structure that keeps fluid moving forward</em></u><em>, it is a blood vessel.
</em>
<em> e. </em><u><em>Lower, pointed region of the heart</em></u><em>, corresponds to the cardiac apex.</em>
Answer:
The number of needed subjects to estimate the mean HDL= 31
Explanation:
Given that:
. standard deviation, s= 11.6
. Margin of error, ME = 2
s= 11.6
ME = 2
. The 90% margin of error is defined as:
ME = Z₀,₉÷₂ X σ÷√η
coeficient = (0,90/2)
2= 1.645 x 11.6/√η
√η= (1.645 x 11.6)÷ 2
η= √9.541
η= 30.888
η≈31
