When blood pressure receptors sense a loss of blood pressure, they decrease their firing rate to the medulla.
Baroreceptors or blood pressure receptors are the receptors present in the carotid sinus i.e. the bifurcation of the external and internal carotids and in the aortic arches.
They are important to maintain the blood pressure in the body. whenever there is a change in the blood pressure they send information to the brain so that the pressure can be maintained.
They are able to sense the pressure change for only short period pressure change. When the pressure change occurs over a long period of time they get adjusted to it.

Arteries
The arteries are the blood vessels
that carry repeated loads of oxygen-rich blood from the heart to all parts of
the body. Arteries are muscular and elastic tubes that operate under high
pressure exerted by the pumping action of the heart. The largest artery is the
aorta while the arteries' smaller branches are called arterioles and
capillaries.
