A: Portal system consists of veins which start from capillaries and end into capillaries.
R: All vertebrates have hepatic portal systems.

The assertion A is true. The portal system is a network of veins that connect two sets of capillaries. It allows for the transport of blood from one set of capillaries to another without passing through the heart.

The reason R is false. While many vertebrates do have hepatic portal systems, not all vertebrates have them. The hepatic portal system is a specific type of portal system that carries blood from the digestive organs to the liver before returning it to the heart. It is found in mammals, including humans, but not in all vertebrates.
