Answer:

<h2>1.45 + 3.55 = 5.0 (total blood volume);  1.45/5.0 × 100 = 29% (low),</h2>

Explanation:

HCT is calculated as:

HCT = Volume of red blood cells / (Volume of red blood cells + volume of plasma) x 100  

1.45 + 3.55 = 5.0 (total blood volume);  1.45/5.0 × 100 = 29% (low), normal range for an adult female HCT  ranges from 38 to 46% (some sources claim 34.9-44.5%).

*for calculating this, one must know two of these three values: packed cell volume, total blood volume, plasma volume.

Total blood volume = Packed cell volume + plasma volume.

Aldosterone ________. A) is secreted by the posterior pituitary B) functions to increase sodium reabsorption C) presence increas
Vesnalui [34]

Answer:

Option B) functions to increase sodium reabsorption.

Explanation:

Aldosterone is an hormone secreted by the cortex of the adrenal gland. The adrenal gland is situated at the superior poles of the right and left kidneys.

Aldosterone regulates sodium homeostasis and as such helps to control blood volume and blood pressure.

Aldosterone is secreted in response to decreased blood pressure (hypotension) to increase sodium reabsorption from urine, sweat, and the gut. Also excessive aldosterone levels (too high sodium) can lead to high blood pressure (hypertension).

They are characterized by coronal mass ejections on the sun's surface. The ejected ionized particles if thrown in the direction of the earth will cause bright aurora as they colide with the earth’s ionosphere and magnetic field. These solar storms can also affect telecommunications satellites and also electricity grid systems.
