Correct Answer is D
Explanation
The correct answer is Choice D.
Choice A rationale:
Vasoconstriction refers to the narrowing of blood vessels. When blood vessels constrict, they reduce the volume of blood that can flow through them, which increases the pressure. However, the flow is decreased, not increased.
Choice B rationale:
As explained above, vasoconstriction increases pressure but decreases flow.
Choice C rationale:
While vasoconstriction does increase pressure, it does not increase flow. Instead, it decreases flow.
Choice D rationale:
Vasoconstriction results in increased pressure and decreased flow. This happens because the narrowing of the blood vessels increases the resistance to blood flow, thereby increasing the pressure. At the same time, the reduced diameter of the blood vessels decreases the amount of blood that can flow through them.
Correct Answer is B
Explanation
The correct answer is Choice B.
Choice A rationale:
Nitrogen is the most abundant gas in the atmosphere, but it is not the primary regulator of respiration.
Choice B rationale:
Carbon dioxide (CO2) is the main chemical regulator of respiration and the potent stimulus of the respiratory centers via the arterial chemoreceptors and directly on the central chemoreceptors.
Choice C rationale:
Oxygen is essential for cellular respiration, but it is not the primary regulator of respiration.
Choice D rationale:
Bicarbonate plays a role in maintaining the pH balance in the blood and is not the primary regulator of respiration.
