Each of the Following Changes Will Result in Increased Blood

Question

Each of the following changes will result in increased blood flow to a tissue except
A) increased hematocrit.
B) increased vessel diameter.
C) increased blood pressure.
D) decreased peripheral resistance.
E) relaxation of precapillary sphincters.

Accepted Answer

Increased hematocrit indicates an increase in the proportion of red blood cells in the blood and can actually lead to reduced blood flow as the blood becomes thicker and more viscous, making it harder to move through narrow blood vessels. The other choices (B, C, D, and E) are all factors that increase blood flow to tissues.
