    Dear Student,

    1) Direct control of water excretion in the kidneys is by vasopressin, or anti-diuretic hormone (ADH) secreted by hypothalamus. ADH causes the insertion of water channels into the membranes of cells lining the collecting ducts, allowing water reabsorption to occur. Without ADH, little water is reabsorbed in the collecting ducts and dilute urine is excreted. Its secretion is controlled by receptors in the hypothalamus that are sensitive to increasing plasma osmolarity, stretch receptors in the atria of the heart, which ...
