Apatient has entered hypovolemic shock after massive blood loss in a car accident. many of the patient's peripheral blood vessels have consequently collapsed. how does the laplace law account for this pathophysiologic phenomenon?
a. blood pressure is no longer able to overcome vessel wall tension.
b. decreasing vessel radii have caused a decrease in blood pressure.
c. wall thickness of small vessels has decreased due to hypotension.
d. decreases in wall tension and blood pressure have caused a sudden increase in vessel radii.
