Dietary Caffeine Increases the Loss of Calcium Through One's Urine

Dietary caffeine increases the loss of calcium through one's urine but is unlikely to cause a dangerous drop in blood calcium levels.The reason for this is that, in response to a drop in blood calcium,

A) calcitriol is synthesized, which activates osteoclasts to break down bone.
B) corticotropin-releasing hormone causes cortisol to be secreted, which triggers the kidneys to retrieve calcium from the urine.
C) the adrenal cortex secretes mineralocorticoids, which cause minerals such as calcium to be resorbed from bone.
D) aldosterone stimulates the kidneys to conserve calcium and excrete potassium.
E) parathyroid hormone is secreted, which causes resorption of calcium from bone and retention of calcium by the kidneys.
