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 D
Explanation
Choice A rationale:
Veins do not always carry deoxygenated blood. The pulmonary veins are an exception as they carry oxygenated blood from the lungs to the heart.
Choice B rationale:
Veins do not carry blood away from the heart. They carry blood back toward the heart.
Choice C rationale:
Veins do not have a thick tunica media. The tunica media is thinner in veins than in arteries.
Choice D rationale:
Veins have valves. This is a true statement. The valves in veins prevent blood from flowing backward.
Correct Answer is C
Explanation
Choice A rationale:
Sinusoids are a type of capillary found in some organs, not vessels that carry blood to the heart from the lungs.
Choice B rationale:
Arteries typically carry oxygenated blood away from the heart to the body’s tissues, not to the heart from the lungs.
Choice C rationale:
Veins, specifically the pulmonary veins, carry oxygenated blood from the lungs to the heart.
Choice D rationale:
Arterioles are small branches of arteries that lead to capillaries, not vessels that carry blood to the heart from the lungs.
