The receptors which note the changes in blood pressure are:
Correct answer: C. Baroreceptors
- A. Caloreceptors
- B. Frigdoreceptors
- C. Baroreceptors
- D. Nociceptors
Explanation
Baroreceptors(Thermoreceptors) detect changes in blood pressure by monitoring the stretch or distortion of arterial walls. Located in the walls of certain blood vessels, particularly in the carotid sinus and aortic arch, these specialized sensory receptors transmit signals to the brainstem in response to alterations in blood pressure. This feedback mechanism allows the body to regulate blood pressure by initiating appropriate cardiovascular adjustments, such as altering heart rate and vascular resistance, to maintain homeostasis.

About Coordination and Control
Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
