Non ACTH mediated hormones - Na+/ homeostasis - ANP

3 important questions on Non ACTH mediated hormones - Na+/ homeostasis - ANP

What is Atrial Natriuretic Peptide (ANP)?

It is a peptide hormone producd by the cardiomyocytes, used for decreasing blood volume and blood pressure

How does ANP decrease blood pressure and volume?

They inhibit ENaC and Na+/K+ ATPase pumps in the kidney tubules, inhibit the release of ADH and decrease the kidney's sensitivity to ADH

How is ANP secretion stimulated?

Increased venous return to the left atrium causes the cardiomyocytes to release ANP

The question on the page originate from the summary of the following study material:

  • A unique study and practice tool
  • Never study anything twice again
  • Get the grades you hope for
  • 100% sure, 100% understanding
