Adaptations to the morphology of the heart are governed by:
A) Frank-Starling mechanism
B) law of LaPlace
C) Fick principle
D) Bohr effect

Question

Quizplus · Accepted Answer

The law of LaPlace governs the adaptations to the morphology of the heart. This law states that wall stress in the heart is proportional to the pressure multiplied by the radius of the chamber, divided by the wall thickness. Therefore, as the heart grows larger to accommodate a greater workload, the walls must thicken in order to maintain wall stress within a safe range.
