GENERAL HISTOLOGY

Detailed explanation-1: -ADH is normally released by the pituitary in response to sensors that detect an increase in blood osmolality (number of dissolved particles in the blood) or decrease in blood volume. The kidneys respond to ADH by conserving water and producing urine that is more concentrated.

Detailed explanation-2: -Secretion of anti-diuretic hormone also occurs if the concentration of salts in the bloodstream increases, for example as a result of not drinking enough water on a hot day. This is detected by special nerve cells in the hypothalamus (osmoreceptors) which simulate anti-diuretic hormone release from the pituitary. .

Detailed explanation-3: -Baroreceptors in the left atrium, carotid artery and aortic arch detect changes in arterial blood volume. If blood pressure reduces, baroreceptors relay this to the vagus nerve, which sends afferent signals that directly stimulates the release of ADH from the posterior pituitary.

Detailed explanation-4: -ADH constantly regulates and balances the amount of water in your blood. Higher water concentration increases the volume and pressure of your blood. Osmotic sensors and baroreceptors work with ADH to maintain water metabolism. Osmotic sensors in the hypothalamus react to the concentration of particles in your blood.
