Question

As blood moves away from the heart toward the tissues, the relative size of blood vessels ________, the blood pressure ________, and the velocity of blood flow ________. as blood moves away from the heart toward the tissues, the relative size of blood vessels ________, the blood pressure ________, and the velocity of blood flow ________. decreases; drops; slows decreases; drops; increases increases; drops; slows decreases; increases; increases

Answer 1

As blood moves away from the heart toward the tissues, the relative size of blood vessels decreases, the blood pressure drops, and the velocity of blood flow slows.

The size of the arteries progressively decreases as they branch out from the major arteries of the body. Once the arteries are the size of the arterioles, the resistance to blood flow increases and velocity of blood flow slows then blood pressure drops.
