Answer 1

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

What is vasopressin?

• 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.
