Question

which of the following statements is false concerning blood vessels? multiple choice as vessel size decreases in cross section, friction increases. as vessel size decreases in cross section, volume increases. as vessel size decreases in cross section, pressure increases.

Explanation:

Blood vessel volume is related to cross - sectional area. As cross - sectional area decreases, volume decreases, not increases. Friction increases with smaller cross - sections as blood has less space to flow smoothly. Pressure also increases as cross - sectional area decreases due to resistance.

Answer:

As vessel size decreases in cross section, volume increases.
