Alexis is out mowing the lawn and starts to feel dehydrated. her will secrete vasopressin. a patient suffering from severe dehydration will have(( first blank )) - hypothalamus - pituitary gland - parathyroid hormone (( second blank )) - increased secretion of vasopressin to maintain more loss of salts - decreased secretion of vasopressin to maintain less loss of water - increased secretion of vasopressin to maintain less loss of water

1. The right answer is - Hypothalamus (manufactured by the hypothalamus, stored in the pituitary gland).

Vasopressin, or antidiuretic hormone, is a peptide hormone synthesized by the supraoptic and paraventricular nuclei of the hypothalamus, and released by the posterior pituitary gland (neurohypophysis).

It mainly has an anti-diuretic role in the kidney, where it causes a reabsorption of water via an action on the distal segment of the nephron during a dehydration body. Its gene is AVP located on human chromosome 20.

2. The right answer is - Increased Secretion of Vasopressin To Maintain Less Loss Of Water.

Vasopressin has an antidiuretic action: it decreases the volume of urine by increasing the water permeability of the collecting tube. It binds to the V2 receptor, which is coupled to a Gα protein, which activates a signaling cascade through the PKA. This causes the synthesis of aquaporin 2 (transmembrane pore) as well as its translocation to the apical / urinary membrane.
