Answer:
The question above is written twice, and without options attached. For comprehension, I would re-write the question with the options attached
Each of the following changes will result in increased blood flow to a tissue except
a. increased vessel diameter.
b. increased blood pressure
c. relaxation of precapillary sphincters
d. increased hematocrit
e. decreased peripheral resistance.
The correct answer is Option D (increased hematocrit)
Step-by-step explanation:
An increase in vessel diameter would lower resistance, thereby increasing blood flow to the tissue.
An increase in blood pressure would increase blood flow to a tissue. This statement is true provided the blood pressure taking blood to tissue is not increased in the arteries.
The relaxation of precapillary sphincters which regulate the flow of blood through capillaries would cause increased blood flow to a tissue.
A decreased peripheral resistance, which means a decrease in resistance of the arteries to blood flow would increase blood flow to a tissue.
While increased hematocrit means increased red blood cells in the total volume of blood causing more thickened blood resulting in reduced blood flow to a tissue.
