Correct Answer is C
Explanation
Answer and explanation
The correct answer is Choice C.
Choice A rationale:
Baroreceptors are sensors located in the blood vessels that detect changes in blood pressure. However, they do not coordinate blood pressure control. They send signals to the brain about blood pressure changes, and the brain coordinates the response.
Choice B rationale:
The brainstem is a part of the brain that connects the cerebrum with the spinal cord. It contains structures that are involved in many vital body functions, including breathing and heart rate regulation. However, it is not the primary structure that coordinates blood pressure control.
Choice C rationale:
The medulla oblongata, a part of the brainstem, contains the cardiovascular centers that coordinate the regulation of heart rate and blood pressure.
Choice D rationale:
The thalamus is a part of the brain that is primarily involved in processing sensory information and regulating consciousness, sleep, and alertness. It does not coordinate blood pressure control.
Correct Answer is A
Explanation
Choice A rationale:
Inhaled food or foreign objects are most likely to lodge in the right bronchus because it is wider and more vertical than the left.
Choice B rationale:
While it is possible for objects to lodge in the left bronchus, it is less common due to its narrower and less vertical structure.
Choice C rationale:
Bronchioles are smaller structures within the respiratory system where foreign objects are less likely to lodge.
Choice D rationale:
The pharynx is not the most common location for inhaled food or foreign objects to lodge.
