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.
It is secreted by the adrenal cortex  (adrenal glands). Antidiuretic hormone is a peptide hormone and is  made by the hypothalamus gland it regulates the body's retention of  water.A decrease is blood pressure triggers the release of the  hormone from the posterior pituitary gland.he 3 hormones that are produced to regulate urine are Aldosterone,  AHD (antidiuretic hormone), and ANH (atrial natriuretic hormone).
