Baroreceptors _______

Question

Baroreceptors _______.
A) are sensitive to changes in blood pressure
B) respond to changes in viscosity
C) are venous receptors that maintain pressure in veins
D) produce aldosterone

Accepted Answer

Baroreceptors are sensory receptors that are sensitive to changes in blood pressure. They are located in the walls of blood vessels and are responsible for helping to regulate blood pressure and heart rate. When blood pressure increases, baroreceptors send signals to the brain to decrease heart rate and dilate blood vessels, which helps to reduce blood pressure. When blood pressure drops, baroreceptors send signals to increase heart rate and constrict blood vessels to raise blood pressure.
