What are two benefits of having a portal system connect the hypothalamus with the anterior pituitary gland? Are there any other endocrine axes connected by a portal system?

One benefit of a portal system is that it ensures that the controlling hormones will be delivered directly to the target cells. Secondly, since the hormones go directly to their target cells without first passing through the general circulation, they are not diluted. The hypothalamus can control the cells of the pituitary with much smaller amounts of releasing and inhibiting hormones than would be necessary if the hormones had to first go through the circulatory pathway before reaching the pituitary. This is the only endocrine portal system.
