Answer to Question 2

B
Feedback:
Antidiuretic hormone is released from the pituitary gland resulting from reduced plasma volume or increased plasma osmotic pressure, so it serves to help maintain blood pressure. Angiotensin II also releases aldosterone from the cortex of the suprarenal gland, which causes retention of sodium and water, leading to the release of ADH to retain water and increase blood volume. Calcitonin maintains a dense, hard bone matrix and lowers blood calcium levels. Growth hormone regulates cell division and protein synthesis necessary for normal growth. Melanocyte-stimulating hormone causes skin pigmentation in humans.
