Carotid sinus senses changes in?

Oxygen Levels
Blood Sugar
Blood Pressure
Temperature

The correct answer is: Blood Pressure

The carotid sinus is a small sensory organ located in the internal carotid artery near the bifurcation of the common carotid artery. It is responsible for sensing changes in blood pressure. The carotid sinus contains baroreceptors that detect changes in blood pressure and relay this information to the brain to help regulate and maintain blood pressure within normal limits. While oxygen levels, blood sugar, and temperature are all important physiological parameters that the body regulates, the carotid sinus specifically senses changes in blood pressure.
