Question

Take a look at the following equation describing Laplace’s law where F = force, D = blood vessel diameter, and P = blood pressure: F = D x P

From this relationship, one can determine that as blood pressure declines, the force acting upon the walls of the blood vessels  ____________ . From this, it is clear that if this force declines below a minimum, blood vessels are in danger of  ____________ .

It can also be seen that as blood vessel  ____________  increases, the force increases. The implication of this is that when an arterial wall becomes weakened and bulges, forming a/an  ____________ , the bulge increases the vessel diameter.

In turn, this  ____________  the force, further  ____________  the bulge.

Ruptures of blood vessels of the brain or aorta are  ____________  fatal.

Answer 1

From this relationship, one can determine that as blood pressure declines, the force acting upon the walls of the blood vessels ___decreases_________ . From this, it is clear that if this force declines below a minimum, blood vessels are in danger of ______collapsing______ .

It can also be seen that as blood vessel ______diameter______ increases, the force increases. The implication of this is that when an arterial wall becomes weakened and bulges, forming a/an ____aneurism________ , the bulge increases the vessel diameter.

In turn, this ___increases_________ the force, further ____increasing________ the bulge.

Ruptures of blood vessels of the brain or aorta are __mostly__________ fatal.
