The Stress Relaxation Response Enables Hollow Organs, Like the Stomach

The stress relaxation response enables hollow organs, like the stomach, to accommodate increases in the volume of its contents. Typically, an upper limit is placed on the volume, however, by

A) reflex contraction initiated in response to stretch.
B) tension due to stretching of the intermediate filaments within the smooth muscle.
C) inelastic connective tissue associated with the smooth muscle of the organ.
D) the number of cross-bridge sites present on the myosin filaments.
