Which of the following is attributable to atrial natriuretic peptide (ANP)? ANP is released when blood pressure is reduced. ANP stimulates sodium reabsorption in the distal parts of the nephron. ANP inhibits renin secretion by granular cells. ANP stimulates aldosterone secretion by the adrenal cortex. ANP stimulates sympathetic nervous system activity to the heart and blood vessels.

Under the influence of atrial natriuretic hormone (ANP), which of the following effects would you expect to observe? A decrease in urine volume. An increase in sodium reabsorption. An increase in urine volume. A decrease in plasma proteins. An increase in plasma volume.
Adi S.
Atrial natriuretic peptide (ANP) is a hormone released by the atria of the heart that Select one: a. acts as a neurotransmitter in the ANS. b. reduces loss of water in the urine. c. stimulates changes that lead to decreased blood pressure. d. reduces loss of sodium in the urine. e. increases blood volume.
Joanna Q.
The atrial natriuretic peptide (ANP) lowers blood pressure by acting as a vasodilator. It is released by cells in the atrium of the heart in response to high blood pressure and in patients with sleep apnea. ANP prevents sodium reabsorption by the renal tubules. Therefore, what excretory system symptom might someone with sleep apnea also experience and why? a. reduction in urination due to reduction of water reabsorption in the kidneys b. excessive sodium reabsorption by renal tubes due to increase in water reabsorption in the kidneys c. excessive sodium reabsorption by renal tubes due to reduction of water reabsorption in the kidneys d. excessive urination due to reduction of water reabsorption in the kidneys
