What is a portal system and how does it function?
What will be an ideal response?
Blood vessels linking two capillary beds make up a portal system, which provides an efficient means of chemical communication by ensuring that all of the blood entering the portal vessels reaches the intended target cells prior to returning to the general circulation. The communication is strictly one way, but is facilitated by openings or fenestrations in the capillary walls that permit easier entry of the chemicals to be transported.
