THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -Antidiuretic hormone is made by a part of the brain called the hypothalamus and is secreted into the blood by the pituitary gland. Certain types of tumors may release high amounts of antidiuretic hormone, which can cause low levels of sodium in the blood and the body to retain water.

Detailed explanation-2: -When the body loses water (i.e., through sweating during exercise, vomiting, diarrhea), dehydration may occur and the plasma solute concentration increases. The hypothalamic osmoreceptors then initiate the release of ADH from the posterior pituitary gland.

Detailed explanation-3: -Your hypothalamus, an area at the base of your brain, produces ADH. Sensors in your body detect when your blood volume changes and needs more ADH. These sensors talk to your brain and the pituitary gland releases ADH into your bloodstream.
