How are pituitary gland hormones distributed to organs throughout the body?

A) via axons
B) via the hypothalamus
C) through the bloodstream
D) through lymphatic vessels
E) via duct systems

Pituitary gland hormones are secreted into the bloodstream and then circulate throughout the body, binding to receptors on target organs and tissues. Axons are involved in the release of hormones from the hypothalamus to the posterior pituitary gland, but not in the distribution of pituitary hormones to organs throughout the body. The hypothalamus does regulate the release of pituitary hormones, but it is not involved in the distribution process. Lymphatic vessels and duct systems are not involved in the distribution of pituitary hormones.
