Verified step by step guidance

Understand the role of calcitonin: Calcitonin is a hormone produced by the thyroid gland that helps regulate calcium levels in the blood.

Identify the primary function of calcitonin: Its main function is to lower blood calcium levels when they are too high.

Consider how calcitonin achieves this: Calcitonin reduces blood calcium levels by inhibiting osteoclast activity in the bones, which decreases the release of calcium from bones into the bloodstream.

Evaluate the options given: Since calcitonin's role is to decrease blood calcium levels, look for the option that aligns with this function.

Conclude with the correct event: The correct result of calcitonin secretion is a decrease in blood calcium levels, as it directly relates to the hormone's primary function.
