Prolactin is under negative feedback by I believe dopamine. If you remove the negative feedback (block the portal system) then it will increase the secretion of prolactin

4- Aldosterone. This is b/c aldosterone is responsible for reabsorption of Sodium (Na) and secretion of Potassium (K) out of the body. If you inject KCl, you are increasing the conc. of potassium and the body responds by secreting aldosterone so as to get rid of the extra K.
