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:

Since the options have not been provided the question is incomplete, the complete question is as follows:

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.

B) stretch receptors.

Explanation:

The stretch receptors are the mechanoreceptors these are responsible for connecting the organs and muscles with the neurologically to the medulla of the brain stem. These receptors are present in the arms and leg muscles which helps in stretching of the body. These are also present in the colon wall and the lungs for expansion in digestion and respiration process.

The given situation indicates that the adjustments of the smooth muscles in the walls of vessels is because of the stretch receptors.

answer; the correct answer is (beta)
