Question

The initial physiological regulation of blood pressure involves the action of renin, which is released by the kidneys in response to factors such as decreased blood volume or low blood pressure. Renin acts on angiotensinogen, converting it to angiotensin I, which is then converted to angiotensin II. Angiotensin II causes vasoconstriction and the release of aldosterone, which increases sodium and water reabsorption, ultimately leading to increased blood volume and blood pressure. Antidiuretic hormone (ADH) can also contribute to blood pressure regulation by promoting water reabsorption in the kidneys, but it is not the initial regulator. Production of angiotensin I is a result of the action of renin on angiotensinogen and is not the initial regulator either.
