QuestionSBA
QuestionChoice
Angiotensin II increases K+ excretion in the distal tubule to stimulate aldosterone production. A rise in aldosterone increases Na+ reabsorption which raises plasma volume and maintains osmolarity, increasing blood pressure.

c
Increased tubular K+ excretion
QuestionChoice
Angiotensin II acts on arterioles by causing vasoconstriction which increases blood pressure.
10006672
b
Arterial vasoconstriction
QuestionChoice
Angiotensin II acts on the hypothalamus to increase vasopressin and activate thirst centres, which raises plasma volume and maintains osmolarity, increasing blood pressure.
10006674
d
Increased vasopressin secretion
QuestionChoice
Angiotensin II stimulates the sympathetic nervous system, which can lead to increased vasopressin secretion, cardiovascular response and thirst sensation.

e
Increased sympathetic activity
QuestionChoice
The renin-angiotensin system is stimulated by a decrease in blood pressure. Angiotensin II works to increase blood pressure by acting on multiple systems.
