MCAT Physics Question -- Blood Flow
The flow of blood through the aorta can be approximated with the volumetric flow rate equation. When the smooth muscle of the
aorta contracts, the radius can decrease by as much as 10%. If the blood flow is to remain unchanged, what must happen to the velocity of blood flow in the aorta?
A) decrease by approximately 10%
B) increase by approximately 10%
C) increase by approximately 25%
D) remain unchanged
