Certain blood vessels that contain specialized sensors that detect the level of internal pressure and transmit messages to the nervous system,which then triggers the smooth muscle in the vessel walls to make any needed size adjustments,are called:
A) pressure receptors.
B) stretch receptors.
C) chemoreceptors.
D) volume receptors.

Question

Quizplus · Accepted Answer

These blood vessels containing the specialized sensors are called stretch receptors because they detect changes in the vessel size/stretch and trigger the necessary adjustments in smooth muscle. The other answer choices (pressure receptors, chemoreceptors, and volume receptors) do exist, but they do not specifically describe the function of the sensors in these blood vessels.
