I know that without the portal venous system the substances would travel to the heart and be dispersed around the body, but are there any disadvantages to this system?

Thanks :happy:
 
Well, if the Portal venous system is blocked you can get esophageal varices. Personally, I think that'd be a terrible way to die.

A disadvantage of the working system is it processes drugs taken by mouth. The liver can inactivate quite a lot of it depending on the molecule. Some new drugs are formulated to be activated by the first liver pass.
