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:
Thoracotomy is a surgical procedure to gain access to the thoracic organs, not specifically for removing air from the pleural space.
Choice B rationale:
A lung biopsy involves removing lung tissue for examination, not removing air from the pleural space.
Choice C rationale:
Lung re-expansion is the goal of the procedure, not the procedure itself.
Choice D rationale:
A chest tube is inserted to remove air from the pleural space and re-establish negative pressure so the lung can re-expand3.
