What additional systemic response does ANG II activate to regulate blood pressure?
Understand the Problem
The question is asking about the systemic responses activated by Angiotensin II (ANG II) to regulate blood pressure. It is specifically looking for which additional system, among the options given, is influenced by ANG II in the context of blood pressure regulation.
Answer
Angiotensin II activates aldosterone and ADH release to regulate BP.
Angiotensin II not only causes vasoconstriction but also activates the release of aldosterone from the adrenal glands and the release of antidiuretic hormone (ADH) from the pituitary gland to regulate blood pressure.
Answer for screen readers
Angiotensin II not only causes vasoconstriction but also activates the release of aldosterone from the adrenal glands and the release of antidiuretic hormone (ADH) from the pituitary gland to regulate blood pressure.
More Information
The release of aldosterone leads to sodium and water retention, increasing blood volume and pressure. ADH contributes to water reabsorption in the kidneys, further increasing blood pressure.
Tips
Mistaking the role of angiotensin II as being limited to vasoconstriction. It also impacts hormonal activity.
