oxytocin and vasopressin

Question 12

hormone responsible for milk let down

Answer 12

oxytocin

Question 13

hormone responsible for

Plasma osmolality is monitored by osmoreceptors in the hypothalamus

Increases in osmolality, small changes above normal osmotic pressure, large decreases in blood volume and

decrease in blood pressure stimulates secretion of ADH

Decreases water excretion by kidneys by V2 receptors

Constricts blood vessels via V1 receptors

Increases adrenocorticotropic hormone (V1B receptors)

Answer 13

vasopressin/ADH
