- A. the pituitary and the target organ.
- B. the thymus and the bloodstream.
- C. lymphatic system and the target organ.
- D. central nervous system and the bloodstream.
Correct Answer: A
Rationale: The amount of hormone released is controlled by negative feedback inhibition.

Information is constantly being exchanged via the bloodstream between target organs and endocrine glands.

The second is thyroid crisis. Manipulation of the thyroid during surgery may cause the release of large amounts of thyroid hormones into the bloodstream, creating a thyroid crisis (storm).
