Short-term adjustments in blood pressure are mediated by

Question

Quizplus · Accepted Answer

Short-term adjustments in blood pressure are mediated by both baroreceptor reflexes and changes in cardiac output. Baroreceptors are pressure sensors located in the walls of major blood vessels and the heart that detect changes in blood pressure and send signals to the brain, which then regulates heart rate, blood vessel constriction or dilation, and other factors to maintain blood pressure within a normal range. Changes in cardiac output, which refers to the amount of blood pumped by the heart per minute, can also affect blood pressure in the short term. For example, increased cardiac output due to exercise or stress can cause temporary increases in blood pressure. Renal activity, or the function of the kidneys, plays a crucial role in long-term blood pressure regulation, but is not necessarily involved in short-term adjustments.
