Volume receptors

Volumoreceptors are specialized receptors located in the walls of hollow organs and blood vessels that respond to tissue stretching when cavities and vessels are filled. They allow the body to control the degree of filling of internal cavities and the circulatory system.

Volume receptors are localized in the walls of the heart, lungs, gastrointestinal tract, bladder, and blood vessels. When the walls of these organs and vessels are stretched, volume receptors are excited and generate nerve impulses that enter the central nervous system along afferent nerve fibers. There this signal is perceived as a feeling of filling of one or another organ.

Thus, volume receptors play an important role in maintaining homeostasis of the body, providing information about the degree of filling of internal cavities and vessels. Their signals are used to trigger reflexes that regulate the processes of filling and emptying of hollow organs.
