Uterus muscles and breast tissue
antidiuretic hormone (ADH) location
made in hypothalamus and sent to posterior pituitary gland
antidiuretic hormone (ADH) target organ
kidneys
antidiuretic hormone action
triggers the kidneys to reabsorb water (instead of making it into urine)
helps hold urine through the night

anterior pituitary
Luteinizing hormone (LH) target organ
In females-ovaries
in males- testes
LH (luteinizing hormone) Action
In ovaries- Triggers ovulation each month, stimulates the ovaries to release estrogen and progesterone
In testes- Stimulates testosterone production
