Question

blood pressure sensors
what are the receptors located in blood vessels and the heart that detect changes in blood pressure?

• chemoreceptors
• osmoreceptors
• baroreceptors
• nociceptors

Explanation:

• Chemoreceptors detect chemical changes (e.g., in oxygen, carbon dioxide levels).
• Osmoreceptors detect changes in osmotic pressure (related to water - solute balance).
• Baroreceptors are specialized to sense changes in blood pressure. They are located in blood vessels (like the carotid sinus and aortic arch) and the heart.
• Nociceptors detect painful stimuli.

Answer:

C. Baroreceptors
