Select the correct answer from each drop-down menu. alexis is out mowing the lawn and starts to feel dehydrated. her will secret
Anuta_ua [19.1K]

Her hypothalamus will secrete vasopressin. If her dehydration becomes severe, her secretion of vasopressin will increase.

<h3>What is vasopressin?</h3>
  • The posterior pituitary gland releases the peptide hormone vasopressin, also known as antidiuretic hormone.
  • Which is produced by the supraoptic and paraventricular nuclei of the hypothalamus (neurohypophysis).
  • It primarily functions as an anti-diuretic in the kidney, where it causes the body to reabsorb water by acting on the distal region of the nephron when it is dehydrated.
  • The AVP gene for it is found on human chromosome 20.
  • Vasopressin has an antidiuretic effect; it reduces the volume of urine by raising the collecting tube's water permeability.
  • It attaches to the G protein-coupled V2 receptor, which in turn starts a signaling cascade through the PKA.
  • Aquaporin 2 (a transmembrane pore) is produced as a result, and it is then transported to the apical/urinary membrane.
