Question

Predict the effect of each of the following conditions on blood flow, (A) vasoconstriction of blood vessels in the skin in response to the cold exposure (A) vasodialation of the blood vessels in the skin in response to elevated body temperature (C) polycythemia vera which results in a greatly increased RBC count Predict the effect of each of the following conditions on blood flow, (A) vasoconstriction of blood vessels in the skin in response to the cold exposure (A) vasodialation of the blood vessels in the skin in response to elevated body temperature (C) polycythemia vera which results in a greatly increased RBC count (A) vasoconstriction of blood vessels in the skin in response to the cold exposure (A) vasodialation of the blood vessels in the skin in response to elevated body temperature (C) polycythemia vera which results in a greatly increased RBC count

Explanation / Answer

A) vasoconstriction of blood vessels in the skin in response to the cold exposure reduces the flow of blood. Reduction in the flow of blood leads to retension of body heat.

B) Vasodilation of the blood vessels in the skin in response to elevated body temperature will lead to increased blood flow. Increase in flow of blood will lead to loss of heat.

C) Polycythemia vera leads to reduced blood flow. Due to the increase in production of red blood cells, the viscosity of blood increases which decreases the flow of blood.
