Question

what is portal organ and non-portal organ?​

Answer 1

Answer:

ANSWER

There are two types of portal systems they are Hepatic portal systems and renal portal system. In Hepatic (liver) portal system a vein collects blood from the intestine and passes it to the liver and in renal (kidney) portal system a vein collects blood from renal glomeruli and passes it to peritubular plexus (the blood capillaries that surrounds the proximal and distal convoluted tubules). Both hepatic and renal portal systems are found in fishes, amphibians, and reptiles. In mammals only hepatic portal system is present. Hence A portal system is one in which A vein starts from an organ and ends up in another organ.

So, the correct answer is 'A vein starts from an organ and ends up in another organ'.
