what is the function of calcitonin

regulates blood calcium and phosphorus i response to high calcium levels, stimulates osteoblasts

what is the function of TSH

secretes Aldosterone SALT BOI

what is the function of the endocrine system

secretes hormones directly into the bloodstream (it is ductless)

what is the function of the exocrine glands

secretes hormones/enzymes and wastes into ducts or onto body surfaces

what is the function of the adrenal medulla

secretes nor/epinephrine stimulates a fight or flight with longer lasting effects

what causes an increase in ADH secreation
