5. Trace the path of blood flow by considering movement of a hormone such as ACTH via the blood stream. ACTH is released from the anterior pituitary intro general circulation but ultimately finds its way to the hypothalamus and exerts short loop negative feedback to suppress CRH release. Trace the path of ACTH from the anterior pituitary, through the heart, and ultimately to the hypothalamus.
