Multiple Choice
When atrial natriuretic peptide is released by the heart because of increased blood pressure, it causes __________.
A
vasoconstriction
B
decreased sodium and water reabsorption
C
increased antidiuretic-hormone secretion
D
increased renin secretion
Verified step by step guidance
1
Understand the role of atrial natriuretic peptide (ANP): ANP is a hormone produced by the heart that helps regulate blood pressure and fluid balance.
Recognize the trigger for ANP release: ANP is released in response to increased blood pressure, which is detected by the heart's atria.
Identify the primary action of ANP: ANP works to lower blood pressure by promoting vasodilation, which is the widening of blood vessels.
Explore the effects on kidney function: ANP decreases sodium and water reabsorption in the kidneys, leading to increased urine production and reduced blood volume.
Consider the impact on other hormones: ANP inhibits the secretion of antidiuretic hormone (ADH) and renin, both of which are involved in increasing blood pressure.
