Our pituitary gland and artery simply means it brings oxygenated blood and blood filled with nutrients to the hypothalamus of our body. So basically this blood is carried into the medium eminence of the hypothalamus. It brings the oxygen and the nutrients to the hypothalamus. At the same time the hypothalamus basically produces and releases the hormones into this network of capillaries and then the hormone basically travels down into the portal veins through this region and into the capillaries found in the interior pituitary gland. And we have many of these endocrine glands that can either be stimulated or inhibited by the hormone released by the hypothalamus and that can basically release some type of hormone from the interior pituitary gland into the blood vessel of the bloodstream of our body. So there are six different types of hormones that we should know when it comes to our anterior pituitary gland.
