Vedclass · Answer

(B) portal system is defined as a circulatory pathway where blood,instead of going directly to the heart,passes through an intermediate organ via a portal vein. In this system,a vein starts from one organ (e.g.,the digestive tract) and enters another organ (e.g.,the liver) where it breaks into capillaries before continuing to the heart. Therefore,the correct definition is that a vein enters into an organ other than the heart and breaks into capillaries.
