Respuesta :
The increased osmolarity of the blood stimulates the hypothalamus to stimulate the posterior pituitary to release antidiuretic hormone (ADH).
Antidiuretic hormone (ADH) directs the kidneys to reabsorb water into the bloodstream. A negative feedback system works until the blood volume and osmolarity is restored to normal levels.
The pituitary gland is attached to the hypothalamus through a stalk of blood vessels and nerves. The hypothalamus corresponds with the anterior pituitary by releasing hormones and with the posterior pituitary using nerve impulses.
The hormones made by the posterior pituitary gland include vasopressin and oxytocin. Vasopressin is also known as antidiuretic hormone (ADH) which acts on the kidneys to conserve water. It is also significant for maintaining fluid and electrolyte balance in the body.
