The correct Answer is:
### Step-by-Step Text Solution: 1. **Understanding the Aortic Arch and Carotid Artery Receptors**: - The aortic arch and carotid arteries contain specialized receptors known as chemoreceptors. These receptors play a crucial role in monitoring the chemical composition of the blood. 2. **Identifying the Changes Recognized by the Receptors**: - The primary changes that these receptors can detect are levels of carbon dioxide (CO2) and hydrogen ions (H+). - An increase in CO2 levels or a decrease in blood pH (which corresponds to an increase in H+ ions) indicates that the body may be in a state of acidosis or respiratory distress. 3. **Signaling to the Rhythm Center**: - Once these receptors detect changes in CO2 and H+ levels, they send signals to the respiratory rhythm center located in the brainstem. - This signaling is essential for regulating breathing rates and depth to restore homeostasis. 4. **Remedial Actions**: - The rhythm center responds to the signals by adjusting the respiratory rate. For instance, if CO2 levels are high, the body will increase the breathing rate to expel more CO2 and bring oxygen levels back to normal. ### Summary: The aortic arch and carotid artery receptors recognize changes in carbon dioxide and hydrogen ion concentrations in the blood, which are crucial for maintaining respiratory homeostasis. ---
