Chemoreceptors and heart rate
• Carotid bodies and aortic bodies detect changes primarily in pCO2 and H ion concentration. They also sense decrease in partial pressure of O2, but to a lesser degree than for pCO2 and H ion concentration. • The chemoreceptor trigger zone is an area of the medulla in the brain that receives inputs from blood-borne drugs or hormones, and communicates with the vomiting center (area postrema) to induce vomiting. WebChemoreceptors: They detect an increase in carbon dioxide or a decrease in blood oxygen. Baroreceptors: They detect an increase or decrease in blood pressure. Proprioceptors: They monitor the movement of muscles during exercise. All these receptors signal the cardiac control centre to take necessary actions. Cardiac Control Center
