Question

Blood viscosity is highly variable in healthy individuals under resting conditions

Answer 1

Answer:

I would say that the answer to the question: Blood viscosity is highly variable in healthy individuals under resting conditions, would be, B: False.

Explanation:

Blood viscosity is the density present in the blood due to its charge of cells (red blood cells, white blood cells, and platelets) in relation to the amount of serum, or water, in the mix. This viscosity then, is highly dependent on hematocrit, or the count mostly of red blood cells. There are conditions that can make hematocrit counts rise severely, and make blood more viscous, like extreme temperature conditions, dehydration, or an illness, as well as blood loss. However, in general, under normal conditions, in a healthy person, under resting situations, the hematocrit tends to remain normally at 40%, and blood viscosity remains at a normal level. If hematocrit changes, rises, or falls, then viscosity will also change, but for this to happen, the person must not be meeting resting, and normal, conditions.
