Which brain structure coordinates blood pressure control?.
Baroreceptors.
Brainstem.
Medulla.
Thalamus.
The Correct Answer is C
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
Answer and explanation
The correct answer is Choice A.
Choice A rationale:
The conchae or turbinates are structures in the nasal cavity that increase the surface area of the mucosa exposed to the air. As air passes over the mucosa, it picks up moisture and heat, which helps to humidify and warm the air before it reaches the lungs.
Choice B rationale:
The sphenoid is a bone located at the base of the skull. It does not have a direct role in the heating or humidification of air.
Choice C rationale:
The nasopharynx is part of the pharynx that connects the nasal cavity to the throat. While it does play a role in the passage of air from the nose to the lungs, it is not the primary site where air picks up moisture and heat.
Choice D rationale:
The oropharynx is another part of the pharynx, located below the nasopharynx. It is involved in both respiratory and digestive processes, but it is not the main site where air picks up moisture and heat.
So, the correct answer is Choice A, after analyzing all choices.

Choice D rationale:
Cartilage is a flexible connective tissue found in various parts of the body, but it does not connect muscles to bones.
