The gravitational constant, approximately 6989667400000000000â 6.674Ã10â11 Nâm2/kg2 and denoted by letter G, is an empirical physical constant involved in the calculation(s) of gravitational force between two bodies.
Diabetes insipidus is caused by a lack of antidiuretic hormone (ADH), also called vasopressin, which prevents dehydration, or the kidney's inability to respond to ADH. ADH enables the kidneys to retain water in the body. The hormone is produced in a region of the brain called the hypothalamus. It is stored and released from the pituitary gland, a small gland at the base of the brain. When diabetes insipidus is caused by a lack of ADH, it is called central diabetes insipidus.
Antidiuretic hormone A hormone produced by the pituitary gland that reduces the production of urine in the kidneys and therefore prevents water loss; also called 'vasopressin.'.

When the body is dehydrated it is released into the blood from the posterior pituitary and binds to its receptor in the kidney, acting to produce more water channels the the collecting duct of the kidney allowing for more water to reabsorbed, this also leads to more concentrated urine.
