In the brachial artery

A. False  Pulse waves travel at about ten times the blood velocity.

B. False  It rises; arterial elasticity normally damps the pulse pressure.

C. False  Blood flows off rapidly via collaterals so that little pressure change occurs.

D. True  By the hydrostatic equivalent of the column of blood between it and the heart.

E. False  Brachial arterial pulse pressures are greater due to the superimposition of waves reflected from the end of the arterial tree.
